Description

My system has continued to evolve over the past 5 years with the one constant being the Rockport Arrakis 2 bi-amplified speakers. They have continued to amaze me that as my electronics have changed and continued to improve, the Arrakis have continued to grow with the electronics as well. Every time I thought I had reached their sonic limit, I have been proven wrong and I am very happy about that.

I have now completely eliminated all tube based components in my system. I have always felt that if I could get the sound that I wanted without tubes, that would be wonderful but I never thought that would be possible. The combination of the TotalDAC digital front end and the Steve Dobbins Beat SE turntable and LT tonearm paired with the CH Precision P1 phono stage, the CH Precision L10 line stage and the CH Precision M10 amplifiers (run in active bi-amplification mode) have achieved this for me.

Components Toggle details

    • CH Precision C10 DAC
    I have upgraded to the CH C10 replacing the CH C1.2 DAC with X1 power supply.
    • Roon Nucleus Plus

    • Nordost QNET
    Nordost QNET Switch powered by the Nordost QSOURCE LPS.
    • Nordost Odin Gold power cord
    I am using a Nordost Odin Gold power cord for Nordost QSOURCE LPS that powers the Nordost QNET Switch and several Nordost QPOINT resonators.
    • Nordost Valhalla 2 Ethernet Cables (2)
    I am using 2 of the Nordost Valhalla 2 ethernet cables. The first one connects between the QNET Switch and the Roon Nucleus Plus. The second is from the QNET switch to the CH Precision C10 DAC.
    • Nordost Odin 2 XLR IC
    Nordost Odin 2 Balanced IC's from the CH Precision C10 DAC to the CH Precision L10 true monaural preamp.
    • Shunyata Research Everest 8000 Power Distributor
    I am now using the Shunyata Everest 8000 power distributor which has replaced the Shunyata Triton V3 in my system for my front end electronics. I use a Nordost Odin Gold power cord for the Everest.
    • Shunyata Research Hydra DPC 6 V3 power conditioner
    I have the Shunyata DPC 6 V3 power conditioner for my computer based audio gear. I have my Nordost Qsource LPS plugged into the DPC 6 V3. 
    The DPC 6 V3 is powered by an Echole Omnia power cord from a wall outlet.
    • Steve Dobbins The Beat SE
    I have recently replaced my wonderful Steve Dobbins The Beat turntable with Steve's latest turntable, The Beat SE. The Beat SE is a complete and thorough re-design of the original Beat turntable with about 99% of the table different from the original Beat. I have had the original Beat in my system for 8 years and it has undergone several upgrades during this timeframe that always further improved the sonics, but nothing prepared me for the improvement that the Beat SE has made in my analog playback.

    June 29 2021 Update: I just replaced the umbilical power cord connection between the Beat SE power supply and the Beat SE turntable with a new umbilical power cord that Steve worked on with Nordost. The results are simply amazing.

    October 1 2021 Update: Steve has now done further modifications to the Beat SE external power supply with internal wire upgrades with wiring from Nordost as well as adding an external grounding connection that enables me to ground the Beat SE power supply to my CAD GCR reference ground box.
    • Nordost Odin 2 Power Cord
    This Odin 2 power cord is used on the outboard power supply for The Beat SE turntable. This is plugged into the Shunyata Everest 8000 power conditioner.
    • Schroeder LT Tonearm with Magnesium arm tube
    I had my previous Schroeder LT tonearm with wood arm tube modified to the even better LT tonearm with Magnesium arm tube. It has the Lyra Olympus SL cartridge mounted on it and it is truly amazing to hear this combination. This arm has replaced the Reed 2A tonearm on my "Beat" turntable. The Olympus SL has never sounded anything like this.

    June 29 2021 Update: I have upgraded the LT arm cartridge mounting plate for my Lyra Atlas SL Lambda to a new one that consists of a carbon fiber top and bottom plate with a copper plate in the middle between the 2 carbon fiber layers.
    • Schroeder LT tone arm with Magenisum arm tube
    This is a new LT tonearm but now with an arm tube made from Magnesium instead of wood. It is a very significant upgrade in sonics. I plan to have my existing LT arm modified to have the Magnesium arm tube as well.
    • Lyra Atlas SL Lambda cartridge
    I have now replaced my wonderful Lyra Etna SL cartridge with the new Lyra Atlas SL Lambda cartridge. My previous experience was that the original Etna SL cartridge was the best sounding of all of the Lyra cartridges. But not any longer. I was fortunate enough to be able to compare the new Lambda versions of the Etna SL and the Atlas SL in my system and the Atlas SL Lambda is simply stunning to hear in my system. The new Lambda Etna SL is also wonderful and better than the original Etna SL, but the Lambda Atlas SL is superior in every way.
    • CH Precision True Dual Monaural P10 phono stage
    I have now upgraded my 4 box true mono CH P1/X1 phono stage to the CH Precision P10 4 box True Dual Monaural phono stage. 
    • Nordost Odin Gold Power Cords
    I am now using two of the Nordost Odin Gold Power Cords to power the two power supplies for the CH Precision P10 true dual monaural phono stage.
    • Nordost Odin 2 XLR IC
    I am now using Nordost Odin 2 balanced IC's between the CH Precision P10 true dual monaural phono stage and the CH Precision L10 true dual monaural preamp.
    • Computer Audio Design (CAD) GC3 Ground Controls
    I am using 2 of the CAD GC3 Ground Controls. One GC3 is used for signal ground with each of my CH Precision M10 amplifiers and the second GC3 is used for Earth Ground with my Rockport Arrakis external active crossover.
    • Computer Audio Design (CAD) Ground Control GCR
    I am using the CAD Ground Control Reference (GCR) in my system. This is used for signal grounds for my front end components and the earth ground for my Shunyata Everest 8000 power distributor.
    • CH Precision L10 True Dual Monaural LInestage
    The new CH Precision L10 True Dual Monaural linestage has replaced my long time reference, the CH Precision L1 true dual monaural linestage. As good as the 4 box version of the CH L1 linestage is, The CH Precision L10 True Dual Monaural (4 box) linestage surpasses it in every audio parameter.
    • Nordost Odin Gold Power Cords
    I am using two of the Nordost Odin Gold Power Cords to power the two CH Precision L10 external power supplies for my CH Precision L10 true dual monaural preamp.
    • CH Precision M10 amplifiers
    I now am using the CH Precision M10 mono block amplifiers. I have 2 of these and I run them in their active bi-amplification mode. These have just replaced (11/30/2021) my wonderful CH Precision M1.1 mono block amplifiers.
    • Nordost Odin Gold Power Cords (4)
    I am using 4 of the Nordost Odin Gold power cords on my CH Precision M10 amps. Each CH M10 amp outboard power supply requires 2 power cords each with 20 amp IEC connectors.
    • Nordost Odin 2 XLR IC
    I use a 9 meter run of Nordost Odin 2 XLR IC's from the CH Precision L10 true dual monaural preamp to the Rockport Arrakis 2 external crossover.
    • Rockport Technologies Arrakis 2 External crossover
    This is the active external crossover for the Rockport Arrakis 2 speaker. It takes the feed from the preamplifier and then splits the signal for the bass drivers and all of the upper frequency drivers.
    • Nordost Odin Gold Power Cord
    I am now using a Nordost Odin Gold power cord on my Rockport Arrakis external crossover. This replaced the already great Nordost Odin 2 power cord.
    • Nordost Odin 2 XLR IC
    I am now using 2 pairs of Nordost Odin 2 XLR IC's to connect the Rockport external crossover to the CH Precision M10 amplifiers.
    • Nordost Odin Gold Speaker Cables
    I am using 2 pairs of Nordost Odin Gold speaker cables  to bi-amplify the Rockport Arrakis 2 speakers.
    • Rockport Arrakis 2
    My speakers are the bi ampified version of the Rockport Arrakis 2 with the active external crossover.  I am driving the speakers with a pair of CH Precision M10 amplifiers run in active bi amplification mode.
    • Furutech GTX/NCF outlets
    I have 13 of the Furutech GTX/NCF outlets with the GTX outlet Frames and the 105D NCF Carbon Fiber outlet covers.
    • HRS SXR
    I have 3 of the HRS SXR audio racks. Each rack is a 4 shelf version and I am using M3X2 isolation bases with G7 footers. These racks and bases hold the majority of my front end components. For the SXR base that holds my Beat SE turntable, I have added the SXR solid brace insert.
    • HRS SRX with M3X2 isolation base
    I have 4 of the HRS SRX amp stands with the M3X2 isolation bases with G7 footers, These are for the power supplies and my CH Precision M10 amps.
    • Nordost Sort Kones
    I am now using Nordost Sort Kones under many of my components. I am using a combination of both the BC and TC sort kones. I am using them under all of my TotalDAC digital components - both DACs, the Outboard Reclocker, the Streamer, the Live Power supply, the D1 player and the NAS. I also use them under my Beat SE turntable outboard power supply (not the turntable itself) and my Rockport Arrakis external crossover.
    • Isonic Ultrasonic RCM
    I have added the Isonic ultrasonic RCM. This is a wonderful RCM. I can do up to 10 LP's at once. It doesn't dry the records - but that is simple to do on my Loricraft.
    • Custom LP Record Cabinets
    There are now 3 of these beautiful LP record cabinets that I commissioned a friend to build for me. Its so much easier to find the LP that I am looking for and to put it back than it was with more traditional shelves that I was using before.

System edited: I have sent all 4 of my VTL Siegfried mono block amps back to VTL to be upgraded to the new Siegfried Series 2 amps. I still have another 2 weeks or so to wait for their return. It's alot harder to go without music than I thought it would be but I am looking forward to getting the new amps back.

Hi Jeff,

Thanks very much.

The MSB digital products are certainly some of the best digital available and the best that I have heard in my comparison evaluations.

With MSB's Universal Media Transport (UMT) and their new and improved UMT Plus model you can play SACD's direct to any of their current generation DAC's. You can also send DSD from a music server to any of their DAC's via any of their digital inputs - I2s, USB, SPDIF and AES/EBU (so not limited to USB for DSD).

You must be getting close to receiving your Absolare preamps and amps. Looking forward to hearing your impressions of them.

Hi Lawrence,

I live in Austin and you are welcome to come by and do some listening. There are many fine audio systems in the area as well as other parts of Texas. It would be a fun road trip for you.

Arnie

babybear

Arnie my mouth salivates looking at your MSB stack. I think this may be the best sounding digital out there at this time. Can you play SACD's with your transport direct to the dac. I have quite a few including the Japanese SHSACD and for some reason I prefer redbook to most of these SACD's. The SACD's sound more mechanical and not as organic to me.

jwm

Bear...wondering what part of TX you reside?...If I can get my projects done..... I want to go on a road trip and hope I can stop on by a few hi pertent setups to compare etc...

Hi Albert,

And a very Happy 4th of July to you as well!

Whenever you visit John, just let me know as it would be great to have you over for some listening. I plan to visit John next weekend to hear how his system is sounding. You don't have to wait till fall - as my listening room has a dedicated 3-ton AC unit that keeps it very cool even with all of those tubes.

Anytime starting August should be good for a visit - my system is off line at the moment as I shipped all 4 of my Siegfried mono blocks back to VTL to get them upgraded to the newer Series 2 version. I should have them back in 3 weeks and I am really looking forward to hearing how they sound. The upgrade is supposed to be a very significant sonic improvement. But I must admit, going without music for the past 3.5 weeks has been much harder than I thought it would be!

babybear

Arnie,

(the Rockport Arrakis are just short of 7 feet tall) and it does sound pretty good.

The epitome of humble :-). Safe to say way better than "pretty good" and I intend to take you up on that offer to listen when I visit John Frech.

Maybe we can agree on a good time sometime soon or at least by Fall when Texas weather gives us a break.

Happy 4th of July !

Hi Lawrence,

I was just lucky that I was able to raise the ceiling to 12 feet when I remodeled our home a few years back. But I have to say, I am very happy that I was able to do that as it allows me to use just about any size speaker (the Rockport Arrakis are just short of 7 feet tall) and it does sound pretty good.

Arnie

babybear

Let me just say..that and I hope I do not hurt anyone's feelings..

from my years of this hobby... listening to peoples systems and or there rooms including mine.....these rooms that are between 8-12 feet are not that great... 7feet and 12 feet and up are much better regardless of room size length or width ... 8foot rooms have many problems... flutter, ringing etc...once you get ceiling short or 12 feet and up that's when it gets good...each will have some drawbacks but both of these sizes are better then most..

the engineer types will disagree but they do not listen to music they listen to there lap top measuring software equipment!

I would say you made a very good choice sir...I could only go shorter and i prefer this...

Hi Lawrence.

Thanks very much.

I agree with you 100% about the importance of electric power when it comes to an audio system. To me, its one of the fundamental foundations of any audio system that one must get as good as they can to maximize the sonics regardless of the speakers and electronics.

That's interesting that you are lowering your ceiling - my ceiling height is 12 feet and previously it was 9 feet high - I greatly prefer the 12 foot height. What sonic improvements are you getting with lowering your ceiling?

Arnie

babybear

yea I do what i can...this transformer is an interesting upgrade to say the least...IMO the quality of power can make or break any system regardless how expensive ...if this fails forgetaboutit

this Nasa spec wire I purchased on ebay is a very special wire extremely tight bundled tin plated wire(no resonances)

I am also lowering the ceiling down from 8.5 feet to 7 feet ..text book would say leave it 8.5 but the text book does not listen to music!..

I enjoy seeing/reading about your system

Hi Lawrence,

I sounds like you have done a good job with your electrical power distribution for your audio system. Congratulations.

Hello again....thanks for answering some questions...I sure would like to see some pictures..and what brand load center wire etc did you use?...I just installed a 15kva transformer just for the audio room...with some 2 awg nasa spec teflon wire for powering up the transformer this wire feeds the load center too.... the transformer came out of an old movie theater..was install in 1946 :) they were 12 feet up and weigh about 275lbs each i have too...I should have taken a movie on how i removed them...

Hi Lawrence,

Thanks very much.

The electric power design includes the use of a 10Kva isolation transformer, feeding a dedicated sub panel with bolt-in breakers with 12 dedicated 20 amp outlets. The wiring is manually twisted 10 gauge solid copper strands for positive, neutral and ground, run through flexible steel conduit and uses Hubbell isolated ground outlets. The transformer itself has its own dedicated ground rod - the ground rod has a copper exterior, 2" in diameter with a ceramic center fill. The 11 foot long rod ground hole is back filled with a mixture of betonite and water to achieve very low resistance.

The iso transformer is from a company called Controlled Power Company.

Hope that helps.

Cool system...I am interested in your electrical components(transformer load center etc) care to elaborate?

Thanks

Hi Lloyd,

The bullets are about 6 inches long and not bendable. The spade end of your speaker cable attaches to one end and the other goes to the speaker binding post.

Send me a PM and I can get you the contact info of my friend who is using them with his Wilson speakers.

babybear

They are quite big and presumably solid (not bendable)...can you provide some guidance as to what happens with/without them in place? Thanks!! Also good to know about your friend & Wilsons.

Any chance I might also ping him a message/PM?

Hi Lloyd,

Thanks very much. I've actually been using the Absolare bullets for about 8 months now. I don't remember the retail price exactly but somewhere in the $4k - 5k range for a complete set of 4 bullets.

They work with any speaker cable and any speaker. A friend of mine uses them with his Wilson Alexandria X-2's.

babybear

Hey Arnie,

Congrats...how much are the ABsolare bullets? CAn they be used with any speaker cable?

lloydelee21

Owner
Hi Jeff,

In my system, the Absolare bullets made the following improvements in the sonics of my system:

1. Lowered the noise floor

2. Increased the elegance and finesse of the upper frequencies

3. Increased the top to bottom coherence of the sound

When I first installed the bullets, I couldn't hear any real difference but I kept them in place for about 3 weeks. I then removed them and did some critical listening and the above 3 items improvements were immediately obvious.

Hope that helps.

Arnie

babybear

Arnie could you describe the sound of your system with and without the Absolare speaker bullets? I will have 200 hours on my speakers in three days. I think I still have a long way to go. Jeff

Hi Vincente,

Ah, Dueland CAST capacitors are superb. My version of the Absolare Signature preamp uses Dueland Silver Cast capacitors which I am sure contributes to its superb performance. It has such an effortless and open quality to the sound.

That should be a very nice upgrade for you.

Arnie.

babybear

Hi Arnie,

Not yet. Stillpoints are officially in my list, but I haven`t bought yet.

I am now waiting for a major purchase of Duelund CAST components I ordered so I will have two new Duenlund CAST - only external crossovers made for my speakers (no changes in the circuit, just component upgrade), so this will take some time and a lot of listening for the changes. I am really looking forward to this upgrade.

Cheers,

Hi Vincente,

Hopefully you will be able to compare the Obsession to the Signature in your own system.

Did you ever get a chance to try any of the Stillpoints footers in your system?

Arnie

babybear

Hi Arnie,

Thank you for your response. I will see if I am able to hear both of them in my system (may not be possible).
Cheers,

Vicente
