Description

The primary goal of this room and equipment is to create a dedicated listening room purposed to optimize music playback. Software consists of SACD discs, a music server containing DSD and high resolution Flac files, and ripped RBCD's.

A house addition that included a dedicated media room was completed February 2015.

Acoustic Frontiers (Nyal Mellor) established the optimum room size consistent with the house addition, designed the room acoustics and provided optimum inside wall dimensions.

The media room acoustic "foundation" consists of an isolated wall system comprised of 130 Kinetics IsoMax clips attached to 1-1/2" furring strips nailed to CBS blocks on all four walls. 440 linear feet of 25mm hat channel is supported by the isolation clips. R-11 open faced fiberglass (3-1/2" thickness) fills the empty areas between the CBS walls and drywall. Soundboard XP damped drywall is attached to the hat channel. Acoustic sealant seals the areas between the top, bottom, corner areas of the damped drywall.

The ceiling utilizes Soundboard XP attached to the ceiling joists. The media room attic has R-38 fiberglass insulation. A knee-wall with attached R30 fiberglass insulation separates the media room attic and the original structure interior attic area.

The A/V electronics are served by a dedicated 100A electrical sub-panel with (4) 20A circuits and 20A Furutech GTX-D duplex receptacles. Twisted pair wiring (#12) is used for each circuit with the neutral and hot wires wrapped on 2" centers and the ground wire placed parallel in PVC conduit. A paper presented at the 2010 AES 129th Convention shows this method has the lowest ground voltage induction tested.

The media room has a dedicated 1-1/2 ton A/C system. Large exhaust ducts in each room corner, and a large return duct on the rear ceiling leading to the air handler/evaporator minimizes room noise.

Acoustic Frontiers incorporated my existing Rives Audio ceiling "clouds" and using room dimensions and frequency measurements specified the interior room acoustic products and locations. The acoustic design creates a flatter frequency response; lowers the room reverberation time; and provides bass trapping. Clarity, sound staging, and imaging are all improved while keeping the room as live as possible.

The interior acoustic panel positioning:
- Ceiling: (4) 6'x6' wood frame acoustic "clouds" hung with all thread from the ceiling joists room centered. Each wood frame consists of (4) 2'x4' RPG BAD panels supported by the frame support structure. UltraTouch R19 sound absorption batts are placed on top of the structure.
- Front wall: (2) 39"x59" RPG Modex type 1 plates (outward positions), (2) 39"x59" RPG Modex broadband panels (inward positions). Panels with 6" spacing except at side walls, hung 23" from floor.
- Side walls: (3) 2'x2' RPG BAD ARC panels @ the L/R wall first reflection points; (3) 2'x2' Listen Audio natural birch diffusers @ the L/R 2nd reflection points; (3) 2'x2' Listen Audio natural birch diffusers flanking the listening positions on the R sidewall and behind the listening positions on the L sidewall. All panels hung 18" from floor.
- Rear wall: (1) 6'x6'x12"d absorber box (R38 fiberglass filled) centered. The existing floor standing RPG BAD panel templates wrapped with acoustic cloth attached to the front of the absorber box. The absorber box is hung 26" from the floor.

Room dimensions, equipment positions, D3 Measurements: see Media Room Floor Plan drawing in photos.

A JL Audio F212v2 subwoofer has been volume matched and phase degrees aligned with a 90Hz crossover, DARO applied. DH Labs SubSonic II RCA cables are connected to the F212v2 from the JL Audio CR-1. The CR-1 is set with a 24 dB octave slope. The (3) D3 bass ports have are plugged with closed cell poly foam to prevent front wall reflections. The system has a palpable low end that blends completely with the stereo speakers. The stereo amp no longer has to support low bass, and the mids and highs from my D3s are appreciable improved.

A JVC RS2000 front projector is suspended from the rear ceiling; Definitive Technology SR-8080BP surrounds are hung on rear left/right walls 6' above the listening position, and a DaLite JKP Affinity 16:9 (67.5 X 120" viewing area) motorized screen hung from ceiling at the front wall.

A solid "system foundation" ensures optimum performance of audio equipment:
- precise stereo speaker positioning relative to front, back, parallel walls; the listening position; and away from obstacles;
- Room acoustics designed to minimize sound reflections and room modes that can "smear" audio and create spikes and nulls;
- a 100A sub-panel with (4) Dedicated 20A A/V circuits;
- Synergistic cabling (PC's, IC's, SC's) ensures design continuity throughout the electrical path;
- Resonance control to isolate audio equipment EMI and vibration.

Thick wool area rugs with jute are used to partially cover wood floor surfaces at the rear wall, and between the listening position and speakers.

White LED strip lights at the outside perimeter of the ceiling "clouds" provide general purpose room lighting. Blue LED strip lights around inside perimeter of the ceiling "clouds" provide mood lighting.

    Acoustic Frontiers "floating wall" design: The walls and ceiling of the room should be used as a component of the overall acoustic design. If properly designed they can provide invisible absorption. Sound energy excites the shell into motion. The mass of the shell and depth of the air cavity form a resonant system. The motion is damped by frictional losses in the wall material. The absorption frequency can be tuned by changing the mass of the wall, the method of attachment to the structural framing members and the depth of the air cavity. Damped drywall is useful because its resonances are subdued relative to those seen in normal drywall, which tends to vibrate at around 60Hz. As in if you energize the room with a 60Hz note the drywall will keep on ringing (making sound) after the note has stopped. A single 5/8″ layer of pre-fabricated damped drywall works great as one component of a "floating" wall system. All wall and ceiling corners are sealed with acoustic caulking.

I am finally convinced a properly integrated subwoofer is essential for all but a few very high end speakers having separate subwoofer towers.

In 2019 I bought a JL Audio F212v2 and the CR-1 crossover. JL Audio T/S helped me with positioning and setting the phase degree for my room. The subwoofer bass sounds like it's an integral part of my stereo system.

I'm now listening to music with a palpable low end. And because my stereo amp has been relieved of supporting bass, the mids and highs from my stereo speakers has appreciable improved.

I'm now a subwoofer advocate.

After I decided to install a subwoofer and active crossover, I needed additional cabling. I considered more Nordost Valhalla because I've read from informed sources it's best to stay with a single manufacturer. But I've been a fan of Michael Borresen since 2011 when I first heard the Raidho line of speakers at RMAF. Borresen has a degree in physics, was a designer at Nordost and other Scandinavian audio companies, and was the designer of Raidho. Borresen and Lars Kristensen started Ansuz Acoustics a few years ago. Borresen designed Ansuz PC's and power conditioners/distributors using both physics principles and critical listening. Based on Borresen's experience with Nordost I believed the Ansuz cables would have a similar sound, and I was right.

I purchased two Ansuz PC's: one to run from the Furutech duplex wall receptacle to an Ansuz Mains8 D-TC, and the other from the Mains8 to the EMM Labs XDS1v2 together with a Ansuz C2 XLR IC to connect the XDS1 to the JRDG Corus. I also used Ansuz Darkz DTC resonance controls under the XDS1 and Mains8. That allowed me to free up a set of Nordost Ti Pulsar Points under the JL Audio CR-1 (once again reinforcing the benefit of resonance control).

I've also spent quite a lot of time precisely integrating the subwoofer phase around the 80 hz frequency so that the sub and Raidho D3s sound as one. The power and sub changes improved the dynamics and resolution of the music playback where I can now hear very subtle parts of the music reproduction such as the reverberation of strings and drum kits, sound wave from cymbals, and the air from brass instruments. The improved dynamics have also added a more lifelike character to both instruments and vocalists.

I resisted inserting a subwoofer and crossover into my system for years believing the main speakers could perform that function well - they simply can't except for perhaps a few at the very top end. And while I knew good power was very important (it's what we hear), it turns out I should have prioritized improvements to A/C over other cabling much more. It's taken me a very long time to get to this point, but with well recorded material I can really hear deeply into the music now with a commensurate emotional improvement. Music is so important!

I've owned a number of very good speakers in my life, but only one actually produced bass that got my attention. That was back in the 1980's with the Infinity Beta system that had separate bass and  separate mid-high frequency towers. That is until I recently installed a JL Audio F212v2 and CR1 Active Crossover in my system.

The bass is now not only prodigious, but after adjusting for phase alignment has a timbre complimenting the main speakers. The Raidho D3 imaging has been spectacular from the beginning, but now the mids and highs have an airiness and definition that makes the instruments and voices sound like they're suspended in air.

JL Audio customer service has been phenomenally patient and knowledgeable helping me integrate the subwoofer with the main speakers. It's been too long ago to remember any real detail of the Infinity Beta, just a general impression of awesomeness. But I think the setup I have now has a full range impressiveness not unlike what I remember with the Beta's.

When the room was being designed I was told there are few speakers at any price point that wouldn't benefit from a well integrated subwoofer with a crossover. I'm now a believer.

I've ordered a JL Audio CR-1 Analog crossover. It will reroute frequencies <90hz from my Raidho C3 to my JL Audio F212v2 sub. I expect it will take some time to get it right, but this change will improve the quality of the sound emensly. Read my update of the system description describing the equipment. I'll repost when the integration is complete. Exciting🙃

Last week I added a JL Audio Fathom F212v2 subwoofer to replace my Definitive Technology SC8000. The F212v2 is positioned near the left rear corner based on my Acoustic Frontiers (Nyal Mellor) room design. I used the D.A.R.O technology that uses a powerful on-board DSP to automatically optimize the subwoofer's in-room frequency response. During the next several days I tweaked the LP @ 60Hz with a 24 dB/octave slope and -3dB ELF trim. With these adjustments the sub integrates well with the stereo speakers. The F212v2 has strikinly improved the timbre and authority of bass over the SC8000. Standing bass, drum kits, and even a Fender Rhodes actually have definition in the lower registers. I'm going to listen to this configuration for a few months, but I'm still planning on adding a JL Audio CR1 crossover "dialed in" by Nyal. I'm convinced the bass in all but a very few main speakers is inconsequential compared to the mid and high frequencies. Let the main speakers handle those frequencies coupled with a great subwoofer for the low frequencies. In all but a very few cases this configuration will create better sound and considerably more enjoyment than spending a fortune trying to get good bass out of stereo speakers. I could have used D2's or possibly D1's rather than D3's to get the incredible resolution, articulation, and 3-dimensional imaging.

My understanding has been an external crossover is required to control both the sub and main speakers to properly integrate low/mid level frequencies. Thus I had been considering buying a JL Audio CR1 crossover and possibly a matching e-sub.

Instead I decided to try using one channel from my JRDG Corus to the line level input of my Definitive Technology SC8000 sub setting the crossover point 40 Hz. I had previously only used the sub which is located in the rear of my room for movies surround sound.

Since I'm using only the subs internal crossover, full bass is still being sent to the front speakers. I expected to hear bass overhang, but to my surprise there's very little to my ear. The low/mid frequency integration may be better with an external crossover, but this change has made a significant difference with my stereo listening. Not only am I now hearing tight low level bass with punch, but the soundstage sounds even bigger.

I'm now planning on buying a pair of reasonably priced DH Labs subwoofer cables to feed both line level sub channels from the Corus. Although both Stereo channels are mono and contain the same frequency output, I understand using both channels provides more gain.

Owner
I agree the power cords make a significant difference. I'm using a V2 2M pc to my amp and a V1 to my Qbase 4. I'll have to look into the Nordost trade-up program since I would like to change all my pc's to V2. Thanks Ron.

I can attest building a dedicated room with good acoustics made a world of difference. When my audio system was in the FR any type of upgrade was more subtle and less satisfying.

It's been 2+ weeks since I upgraded to the Valhalla V2 speaker cables. This change produced obviously better articulation, and instrument specificity in terms of timbre and soundstage placement. I can't actually say this was a cost effective improvement given the cost of the Valhalla V2, but there's no question it has raised my listening enjoyment.

I had JRDG upgrade my 625 amplifier to the S2 level. I received the unit yesterday and listened for about 5 hours last night. The 625 was really good before, but the S2 version is even more analog sounding and organic - more presence and impact.

The RPG modex type 1 (outside positions) and modex broadband (inside positions) have arrived. They've been temporarily placed on the front wall floor roughly at the horizontal positions they will occupy when hung on the wall 23" above the floor.

The RPG BAD ARC panels have arrived. They've been temporarily placed on the side wall floors at the first reflection points. They will be hung in the same vertical alignment as the Listen Audio birch diffusor panels.

The installer will hang all panels on the wall this coming week.

Acoustic Frontiers (Nyal) told me I'm only hearing about 70% of the improvement with the panels on the floor. I can clearly hear the room's reverberation time has been significantly lowered, voice and instrument articulation and soundstage definition has improved, the low end is tighter and more pronounced.

Unfortunately I can't post pictures on my virtual system page. The Audiogon staff is telling me they're working on a problem with that portion of the website.

I have posted the pictures here:

System edited: The Listen Audio diffusers were installed today on the left and right side walls. The exact positions were specified by Acoustic Frontiers. The RPG modex plates and BAD ARC panels should arrive and be installed sometime during the first half of August. The local company that installed the diffusers today is building the rear wall absorber box. One of the three RPG BAD templates currently used in the floor standing frames was disassembled today. The installer took that one RPG BAD template with them for sizing since all three templates will form the front of the absorber box.

The big change between the C3.0 and C3.1 is the improved tweeter because it covers such a large frequency band. The C3.1 tweeter membrane is driven over a much larger area and the non-driven areas have been reduced by more than 90%.

I purchased and installed the C3.1 tweeters in my C3.0's and it was a significant improvement.

There's better articulation, more precise instrument positioning and air, the bass is stronger although perhaps could be slightly better defined.

I'm sure there's going to be some additional acoustic treatments coming, but the room more than meets my initial expectations.

System edited: The past two days the acoustic "clouds" with white led room lighting, projection screen, and front projector mount was moved from the FR ceiling to the new media room ceiling. The acoustic "clouds" dramatically reduced the intensity and duration of the slap echo in the room. I'm now optimistic when the wood floor, furnishings, wool area rugs, equipment, and remaining front wall acoustic floor panels are moved into the room; the audio will sound pretty good for starters. By the end of this week the addition wood floors, the door trim & baseboard, solid-core doors including the sealed media room door with threshold will be completed. I'm expecting to be able to move my equipment to the new media room in a couple of weeks. Can't wait!

System edited: With help from my dealer I was able to install the EMM Labs MDAT2 firmware update this past Saturday on my XDS1 v2. I was immediately struck by the increased articulation, openness, inner detail and separation, the increased attack and authority. The bass is most obviously better defined and solid. This upgrade is indeed not subtle! It's truly amazing what mathematics can do for music!

System edited: Soundboard XP ceiling (knockdown) and walls (orange peel) were completed this week. The trim carpentry will be next for the room including the sealed solid core door at the entrance. The finished wall dimensions (15'-3 3/8"W x 19'-6 1/2"L x 11'H) are very close to the acoustic design plan. Probably not surprisingly the room has a major slap echo at this point. But you can hear a deepening of voices when entering the room resulting from the "floating" wall system. Hopefully the echo will be considerably reduced or eliminated when the acoustic "clouds" are moved from the FR ceiling to the new media room ceiling, the "floating" wood floors are installed, furnishings are added along with the wool area rug from the FR, and the floor standing RPG BAD panels at the speaker first reflection points are in place. Hopefully I'll be listening to music in this room by early March. I'm sure over the next 6 - 12 months listening will reveal if and where additional acoustic treatments may be needed.

I am excited about having a dedicated listening room built with acoustics designed into the plan vis-a-vie the room size, "floating" wall system, and dedicated power. But I'm not sure if I'm going to implement the full acoustic design envisioned. I'll start with the RPG BAD ceiling "clouds" moved from the FR, and the (3) RPG BAD panels positioned at the first reflection points on the front wall and right front side wall. That's the same acoustics I'm using now in the FR that sound very good. The only thing I may do extra initially in the new media room is have the contractor build a 6'h x 6'w x 12"d frame on the rear wall screwed into the hat channel and filled with fiberglass for absorption. The designer recommended the frame faced with the (3) RPG BAD panels, but I would replace the RPG BAD panels with (3) absorber panels I have in the FR upper decorator area.

The current media room state consists of the "floating" wall system comprised of 130 Kinetics Isomax clips screwed to 1-1/2" furring strips nailed to CBS blocks on all four walls, and 440 linear feet of hat channel. R-11 open faced fiberglass (3-1/2" thickness) will be added behind the hat channel, and damped drywall will be screwed to the front of the hat channel. The whole "floating" wall system will add 3-1/2" to each CBS wall, but the finished room dimensions will be very close to the optimum room size (19-1/2'L x 15-1/2'W x 11'H) recommended by Acoustic Frontiers.

The media room A/V electronics will be served by a dedicated 100A electrical sub-panel with (4) 20A circuits on the same phase. The #12 wiring for each circuit will have the neutral and hot wires wrapped together (2" centers) with the ground wire placed parallel all in pvc conduit. According to an AES paper, documented testing confirmed this method had the lowest ground voltage induction of anything tested.

The media room will also have a dedicated Carrier 1-1/2 ton A/C system. There are (4) large exhaust ducts (1) in each room corner, a large return duct on the rear ceiling, and large A/C ducts to the air handler/evaporator over the garage ceiling. The A/C sub-contractor assured me the system would be quiet.

Thanks Mike. I'll be posting the progress and changing my system pictures as the room nears completion. I didn't think I'd ever have a dedicated listening room, but a combination of circumstances including my wife wanting the family room back made this dream come true.

You have a clean looking listening room similar to my existing room. Despite its asymmetrical shape, open floor plan, and glass, I was able to get that room sounding very good using RPG BAD panels on the ceiling, the front wall areas, and absorbers in the upper decorator areas of the room. I tried not to make too many compromises to the room aesthetics in the process.

I've heard the Elrod PC's are excellent, and have read very positive comments and reviews about Legacy. I like the apparent synergy of your system as I believe it does pay off in better overall sound reproduction. Your audio system must give you great musical pleasure as mine does me.

The new media room wall system is an acoustical starting point. I'm planning on using the RPG BAD panels in the front wall areas similar to the existing room with lots of absorption on the rear wall initially. I'll probably add another RPG BAD panel on the left front side wall, and possibly corner bass traps on the front wall.

The Raidho's and ancillary equipment will likely be setup close to the existing room since the new media room is close to the same size. I'll do a lot of listening and perhaps have the room acoustically measured. I'm sure there will be much more work to do over the next months and/or years to get the room as close to acoustically perfect as possible.

The new house addition is finally weather sealed. The media room portion is beginning to take shape. This past week 1-1/2" furring strips were nailed to the (4) cbs block interior walls. Kinetics Isomax clips were screwed into the furring strips vertically on 24" centers.

Next week the hat channels will be slotted horizontally into the Isomax clip channels. After the electrical and A/C work also scheduled to begin next week is completed, damped drywall will be screwed to the hat channels taking precaution not to touch any portion of the furring strips or block walls. Acoustic caulk will be applied to 1/8" gaps where the drywall meets the floor and ceiling.

The isolated wall system will effectively provide an acoustic foundation for the room, as well providing a sound barrier.

The Qbase is still part of my my system configuration. My equipment is likely to change very little during the next few years. I will apply a EMM XDS1v2 firmware update when it has been fully tested.

Construction of a house addition that will include a dedicated media (listening) room is scheduled to commence shortly and be completed by the end of next February. The media room acoustic design is by Acoustic Frontiers, Fairfax, CA.

The existing listening room will revert to the original family room configuration. All audio-video equipment and the theater seating in that room will be relocated to the addition dedicated media room.

The listening room overall dimensions are 19.5'L X 15.5'W X 11'H. All walls are cbs (no windows) with furring strips, insulation, isolation clips, hat channel, and damped drywall. Damped drywall on ceiling screwed to joists.

The floor is engineered wood (glued or floated) on concrete pad. A wool area rug with jute padding between listening position and speakers.

The ceiling will utilize the (4) 6' X 6' framed RPG BAD panel "clouds" now located in the existing listening room. They'll be suspended about 1' from the ceiling with integrated led room and mood lighting.

The rear wall will use the existing (3) RPG BAD panels in front of a 6'W X 6'H X 2'D frame filled with fiberglass.

If the cost is not prohibitive front and side walls will utilize tuned bass modules, diffusors, and diffusor/absorbers housed in support columns.

Front wall - (4) equally spaced 2'W X 8"D X 10.5'H vertical support columns starting in the corners. The columns in addition to diffusers, consists of (14) 2'W X 2'W tuned membrane bass modules in specific column locations ranging from 29Hz to 109Hz.

Side walls - (3 each) vertical support columns (same size as front wall) from the listening position forward. The columns in addition to diffusers and diffuser/absorbers, consists of (8) tuned membrane bass modules in specific column locations ranging from 58Hz to 116Hz.

If the cost of the columns/tuned modules is excessive, I'll likely listen to the system for sometime before deciding individual acoustic treatments for the front and side walls.

I'll be posting pictures of the addition media room interior construction starting with the "floating wall" system.

System edited: I recently had Acoustic Frontiers perform an acoustic analysis of my current listening room. About 3 1/2 years ago I had used Rives Audio to design the acoustics for my listening room, but I had never had the results analyzed. The analysis showed the room met 16 of 21 acoustic design standards, and considering the asymmetrical room, no glaring issues. But the analysis did point out some potential improvements. The changes I've made so far is to reposition (3) floor standing RPG BAD panels to the front and right side wall speaker mirror points. And thick jude padding under the area rug between the listening position and speakers. Addressing the speaker mirror points eliminated a slight high frequency bump from the right side. But the biggest change was the left soundstage becomming considerably wider than before.

The Raidho C3's resolution and dynamic range is significantly better than the Eben X3. Although the Raidho X3 is also an excellent speaker that possesses probably 75% of the C3.0 without the 3.1 tweeter upgrade.

lwhitefl

Owner
Sorry for the delay responding - I had to work with Audiogon to resolve a userid/pswd mismatch issue. I purchased the 3.1 tweeters directly from Raidho and installed them myself. I only upgraded the 3.1 tweeters as that is the most significant difference with the new speakers. The internal cables are still Nordost Valhalla which I use for all cabling.

The C3 tweeters are responsible for a considerable portion of the high midrange to treble. The change to the 3.1 tweeters is significantly improved resolution and impact in that part of the frequency range.

System edited: Choosing a new digital source was a difficult task given the number of really great players I've heard. After listening to all the top CD/SACD/DAC contenders at RMAF 2011 (EMM, Esoteric, dCS, Playback Designs) I narrowed my decision to the Esoteric K-01 or EMM Labs XDS1. I certainly heard the XDS1 more than the K-01 because of the shear number of manufacturers using that player to display their products at RMAF (although there were a lot of dCS Puccini players being used as well). I also was able to spend several hours listening to the Esoteric K-03 in a very good audio system in Golden Colorado, and the XDS1 in perhaps the best audio system I've ever heard at The Audio Federation in Boulder Colorado after the show. Both EMM and Esoteric are great digital players with different sound and features. The K-01 is built like a tank and features a drive mechanism indisputably tops in the industry. But it has far too many "filter" options, complicating setup and operation. The EMM is built with the philosophy that simpler is better - with top notch quality (a single gain stage from DAC to output with fully discrete Class-A circuitry, proprietary power supply), and while the K-01 sounds more dynamic, the XDS1 sounds more analog and musical.

I had previously been using ASC and Echobuster absorber panels for side wall reflection points, Echobuster P4 Towers used as bass traps at the front wall corners; wood verticals to cover right side wall exterior insulated French doors, wood shutters over the front wall arched windows, and a 6' X 8' wool area rug for absorption on the wood floor between the speakers and listening chairs. I had also been placing Echobuster absorber panels in front of the HDTV during listening sessions - these panels have now been relocated to the left back kitchen wall.

The first phase of acoustic design construction involved the installation of the absorber panels in all the plant decorator areas 8’-12’ above the floors in the listening room and kitchen; this significantly quieted the entire area and greatly improved sound system articulation. Next diffuser panels were built for the breakfast nook area French door and etched window during listening sessions, and again I heard improvements in overall room quietness and audio articulation. The final construction was just completed with installation of the four diffuser clouds in the listening room and the absorber cloud over the rear hallway. This further improved the audio system articulation, but fundamentally and dramatically improved the presence and dynamics of the audio system. Frankly, I’ve only heard a few other audio systems with a similar sound in well designed dedicated listening rooms in south Florida.

I still have to install the led strip lighting around the inside top perimeter crown molding of the small center open box of each “cloud”, but the switched electrical outlets are already functional in the ceiling. I think I’m going to try blue led flex strips http://www.ecolightsolutions.com/led-products/flex-tape.html on one cloud to see what it looks like before making a final decision on the color or whether to put led’s around the outside perimeter of each cloud.

System edited: The acoustic absorber panels consisting of 703 Owens Corning fiberglass (2") wrapped with acoustic cloth have been built and placed on the back walls of all planter decorator areas in the listening room and kitchen. This has significantly quieted the entire area. The result I'm hearing more of the music content with increased articulation. The diffuser panels for the breakfast nook are being built as is the ceiling absorber cloud for the hallway between the kitchen and listening room. The final step will be to build the diffuser clouds for the listening room ceiling after Christmas. I'll continue to post pictures as the Rives Audio room acoustics plan is implemented.

System edited: Working with Rives Audio using level 2 acoustic design service, currently working to finalize concept plan. The drawing shows absorptive panels lining the walls of the plant setback areas in the kitchen and listening room, (4) 6X6 "cloud" panels hanging 9" from listening room ceiling, a 2'-6"X15'X18" drop-down ceiling from StarSilent over the hallway at the rear of the listening room, RPG VariScreen diffusers in front of the breakfast nook French door and arched glass window and Graber cellular shades pulled over breakfast nook butt-glass windows during listening sessions, a 6X8 wool area rug on the breakfast nook tile floor, and a 3X11 wool area rug in the hallway. I'm also using an Echobuster absorptive panel at the first reflection point on the right side wall, the same type panel at the listening chair position on the left side wall, an ASC picture panel at the first reflection point on the left side wall, Echobuster P4 towers (bass traps) in the front wall corners, Echobuster absorber panels in front of the HDTV during listening sessions, and a 6'X8' wool area rug between the speakers and listening position. Audio measurements will be taken before the ceiling "clouds" are installed for fine tuning the final acoustic treatment. This project is going to take me into next year full full implementation.

System edited: Since the listening room is at least as equally important as the audio equipment, I'm currently working with Rives Audio to improve listening room acoustics via their level 2 acoustic design service. To date the listening room area has been defined to the Rives CAD system, and Rives has recommended the best speaker/seating position based on my prioritization of room asthetics. Rives is now working on the conceptual plan that will define the extent of acoutic treatments to the listening room, breakfast nook, and kitchen areas. This phase will be followed by implementing the fundamental acoustic treatments. Though no walls will be moved, acoustic treatments to ceiling areas, glass windows/doors, and decorator setback areas are likely candidates. When this work has been completed, professional acoustical measurements of the listening room will be used to do the final tuning.

Thanks for the post Sam. We are indeed fortunate to be able to enjoy music reproduced at a very high level in our homes. I first heard the Raidho Ayra C3.0 speakers at the 2008 RMAF and thought they were in a small group of speakers representing best of show. I never thought I'd be able to own them, but an Audiogon seller presented me the opportunity and I grabbed them!

I've made a significant number of audio system changes since that 2008 RMAF and the C3.0's are certainly the most significant. But perhaps the most valuable changes I've made are attributable a 2008 RMAF siminar I attended that aptly demonstrated power conditioning, synergistic cabling, and resonance control are crucial to hearing the true capabilities of any audio components.

System edited: I began this transformation with my audio system shortly after returning home from the 2008 RMAF. I went to that show with the objective of upgrading my B&W N802 speakers, and I heard some wonderful speakers (Acoustic Zen, Coltrane, Hanson, Kharma, Marten, Raidho, Tidal) that I had never heard before. Although I had previously tried a few modest power conditioning, cabling, and vibration control products, I had always been a little skeptical they could have any significant effect on sonic quality. But I returned home with a set of Nordost Ti Pulsar Points and a new purpose because of what I learned (and heard) in various demonstration rooms and a seminar espousing the virtues of using good power conditioning, synergistic cabling, and resonance control. I visited the Nordost room early the first morning where Lars Kristensen demonstrated the effect of Nordost Odin cabling, Quantum QX4, and Ti Pulsar Points with Raidho Ayra C3.0 speakers. I heard a remarkable improvement when Ti Pulsar Points were inserted under the preamp and CD player. It was hard to believe such a small piece of titanium could improve resolution, articulation and dynamics so significantly. Then we heard a Quantum QX4 that widened and deepened the sound stage also improving dynamics, when the QX4 was switched off the sound stage collapsed towards the center. During the “System Setup & Tuning” seminar on the second day, Roy Gregory told us “you’ll never truly hear your audio system unless you address the system foundation”. RG demonstrated how power conditioning, system cabling, and resonance control could significantly improve the sound of the same modest speakers, preamp, amp, and CD player. The demonstration played the same music selections beginning without power conditioning, inconsistent cabling, and no resonance control to a full out assault which included a Stillpoints rack, Vertex cabling, and a Quantum QX4. The resulting improvement in coherence, resolution, and dynamics was anything but subtle! Returning home I placed the set of Ti pulsar points under the CD player with no other audio component changes and immediately heard improvements with articulation, resolution, presence, instrumental air, and dynamics. I purchased two additional sets of Ti pulsar points for my preamp and amp and heard more sonic improvements of the same nature. My next purchase was the Quantum QX4 power enhancer which did indeed widen and deepen the soundstage. I was very pleased with the improvement in my B&W N802 based system and that was the extent of the changes I made to my audio system in 2008. At the beginning of 2009 I had an opportunity to purchase a pair of Raidho Eben X3.0 speakers. Even though I had not heard them, the Eben’s had a similar size and the same drivers as the Raidho Ayra C3.0’s that so impressed me at RMAF. I replaced my B&W N802’s with the Eben’s towards the end of January 2009 and had a new reference speaker system in place. The Eben’s produced a degree of articulation, resolution, timbre, and dynamics (particularly at the low end) I had never experienced with the N802’s in my listening room. I listened for about two weeks before deciding to make additional system foundation changes. I had been using a mixture of modest system cabling (DH Labs, Straightwire, Krell CAST) and decided to use cabling from the same manufacturer. I first changed the all the power cables on my preamp, amp, CD player, and QX4 to Nordost Brahma and again heard system dynamics and articulation improve. Next I changed the speaker cables to Nordost Frey and sonic improvements became still more pronounced. Next I changed the IC’s on my CD player to Nordost Valhalla and heard a significant improvement in resolution and articulation – I should have changed that first! Finally I changed the regular Krell CAST to MMF CAST and heard another incremental improvement. This year I incredulously had an opportunity to purchase a pair of Raidho Ayra C3.0 speakers, the very speakers I had heard and admired so much at the 2008 RMAF. I also decided to use a Lindemann preamp and amp with the Ayra’s because they work really well with Raidho speakers. The transformation is now complete – at least for the foreseeable future. My audio system has now moved to a new plateau of music reproduction. The solid system foundation allows me to easily hear even subtle differences in equipment and recordings. My audio system now reproduces music with a higher level of presence, timbre, coherence, resolution, articulation, authority, and great imaging I’ve previously not heard. The speakers literally disappear allowing me to focus on listening to the various instruments collaborating to create great music. I’m sure there are other audio systems setups in great listening rooms with even greater sonic realism, and I’m certain improvements can still be made to my audio system, particularly the cabling and digital front end. But I’m amazed by this experience and immensely enjoying reproduced music more than ever. I’ve been intently listening to music from my audio systems since I was a teenager, and since retiring on average five days a week, 3 - 4 hours a day. I receive immense pleasure from well reproduced music! So much so that I’ve found many “live” (amplified) musical events lacking the quality of the music I’m able to hear at home. I'm certainly enjoying my audio system!

Thanks Samhar - the arched windows aren't as much of a detriment to the sound as one might think, probably because the bottom of the window is 42" off the floor. But I agree, it's a difficult room because of the open floor plan with glass windows and doors everywhere. The room acoustic pieces I have in the room help considerably. Perhaps one day I'll get that dedicated listening room.

The X3.0's are internally wired with Nordost and the Raidho speakers I heard at RMAF sounded awesome with all Nordost cabling. Nordost cable is pricey, but the company has consistently been a R&D leader in cabling. And like you I've been able to buy from fellow Audiogon members which has made my system possible.

If you can find a dealer in your area that carries the Nordost product line, I urge you to consider giving Quantum QX4 a listen. It significantly increases the width and depth of the soundstage. HiFi+ gave it their 2008 Discovery award.

I've also been amazed at how much the Ti Pulsar Points increased articulation and tightened the sound in my audio system. The X3.0's use Cold Ray resonance control devices to effectively decouple the speakers from the floor as well.

I heard the Sophia's in an audio friends dedicated listening room last year and they sounded really good. It looks like you've put together a really good system in a short space of time and that you too are really enjoying music. I encourage you to pay close attention to your "system foundation" (including a dedicated electric line). I agree with HiFi+ - it will pay big dividends.

System edited: Major changes to my audio system since I attended RMAF last October 2008. At RMAF I attended a HiFi+ setup and tuning seminar emphasizing the importance of the "system foundation" to optimize audio performance in any system. This includes power supply conditioning, resonance control, and consistency in cables (all from same manufacturer). I heard Raidho speakers in the Nordost room at RMAF and thought they were one of the best speakers at the show. I now have a pair of Eben X3.0's I purchased on Audiogon. The system is still not broken in because I have just now completed all the system updates. But the coherence, articulation, timbre, imaging, and dynamic range of my newly updated system is a significant improvement. I'm enjoying music more than ever (SACD, RBCD) - now if I could only swing a dedicated listening room!
