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.

Hi VPN,

I did compare the Echole Obsession in my system to the Echole Signature IC's and power cords and to me the Signature were a very nice step up in performance. The cables have a very similiar tonal balance given they both use the same alloy wire (silver, gold and palladium) but the mix of the alloy is different with the Signature and the overall gauge of the wire is thicker. I found that the biggest improvements were in the frequency extremes - more resolved and powerful bass and more harmonically rich in the upper frequencies. I have a friend here locally who did the same comparison very recently and heard the same results and he ended up getting the Signature IC's and Speaker cables.

Obviously the Signature cables are not 80% better than the Obsession but they are a definite sonic improvement that I think you would easily hear in your system. But, they are quite a bit more expensive as well.

Hope that helps,

Arnie

Hello Babybear,

I have a pair of Echole Obsession interconnects and I am considering buying more. The Echole Signature is about 80% more expensive than the Obsession, so I will probably stick to the Obsession, but I wanted to have a word from you on how much better is the Signature. If could give me a sense of the magnitude of the difference it would be highly appreciated.
Cheers,

Hi Peter,

Thanks very much!

If you are ever coming to Texas, let me know as you are very welcome to come by for some listening.

Babybear, All I can say is WOW. I just looked up your system for the first time. It must sound fantastic. Yours is one of the systems on Audiogon that I would really love to hear. I heard "The Beat" at RMAF 2010. That is an excellent table. Congratulations.

System edited: I made some changes last week. My dedicated room is also used for Home Theater and I have been using a fixed mount Stewart Studiotek 130 G3 screen. For 2 channel listening I would mount 3 fairly heavy acoustic panels over the screen which made significant improvements in the sound. I've been wanting to get a motorized screen for some time now so that it would be easier to go between home theater and 2 channel. I've been waiting for the Screen Innovations Black Diamond motorized screen to come to market and it finally has and I have one installed now. For those of you who have projection screen setups, the SI Black Diamond screens (fixed or motorized) are simply amazing. In addition, I reworked the acoustic panel setup on the front wall behind the speakers. The 2 channel sound is even better now. The old screen/acoustic panels can be seen in the first photograph and the new setup is shown in the third picture.

To be assumed...;) Nevertheless, i have promised myself never to go down that dark road...;) Thanks for the feedback.

Hi Lloyd,

I do have Saxophone Colossus and Waltz for Debby on CD but not on vinyl. We didn't do the comparison while I had the Revox R2R here, but I am very confident that there wouldn't be much comparison between the digital format and the R2R format. The realism that was presented by the R2R in my system was pretty amazing. Waltz for Debby definitely created the illusion of being at the Vanguard will Bill Evans. The vocals on Mose Allison - Creek Bank were so realistic sounding and the drum kit on Colossus had a very realistic presence in my room.

Arnie.

OK! Nice one! Now...on a scale of 1-100, if you scored the 16/44 redbook version of the above albums on your MSB digital, vs the TT, vs the Tape Project versions...how would you score each medium? Presumably you have at least Saxaphone Colossus and Waltz for Debby?

I had a wonderful opportunity to hear 3 of the Tape Project reel to reel tapes in my system yesterday played back on a Revox professional level tape deck. I heard Sonny Rollins - Saxophone Colossus, Mose Allison - Creek Bank and finally Bill Evans - Waltz for Debby. It was the first time I had heard reel to reel in my system and it was pretty special. A big thanks to my friends Luther and Travis for bringing the deck and tapes for all of us to enjoy! A truly great Sunday afternoon.

Armie,

I guess it shows that tube matching is system dependent. I love your equipment moves.

Hi Darren,

Good to hear from you and thanks very much.

The Echole cables are very good - I am using the Signature version of Kerem's IC's, power cords and speaker cables and couldn't be happier.

Thanks for the tip about the Cryo Gold Lion 12au7 re-issues. I will have to give one a try. My Absolare preamp does indeed use 2 of the 12au7/ECC82 tubes - one tube for input and the second tube is in the output side. The 2 tubes do not need to be the same but they both need to be 12Au7/ECC82 or one of the compatible variants (like 5814, 6189, etc). I actually did try two Telefunken 802s tubes in the Absolare, but i did not like the sound at all. They were very extended with lots of air in the upper frequencies, but a little too thin and analytical sounding.

Arnie,

Just checked in and noticed big changes. Congratulations. I have been keeping put for a while as I feel once I get back on I might lose the magic. In the end it is finding synergy.

I heard the Echole cables years ago on Kaiser speakers at RMAF. One of my favorite setups of all time. The designer of the speakers and cables were in house. One thing I can say, I loved their sonic bias. My kind of sound.

I noticed your new preamp uses 12AU7s if I am not mistaken. My biggest upgrade these days - and it was fairly huge - was changing away from NOS tubes to a pair of Cryo Gold Lion reissues. I know you are using Telefunkens. But for the money, and maybe I am lucky, these are the best tubes I have tried in my VTL pre. It is like I am hearing it for the first time. You might want to give it a shot even on your new pre. First time I tried cryo tubes though. That might be why.

Good luck VPN!

Arnie - you're probably right...but having just bought second hand HRS M3 and nimbus/couplers for Zanden...i am sticking with them. the Ultra 5s are for the Wilson X1s and Velodyne DD18...though i admit i did get Ultra 5 for the CJ and LP Isolator for Transport...that's enough for now!

They are excellent and addictively good!

Hi Lloyd,

You should definitely give the Ultra 5's (or perhaps the Ultra SS's) a try under your Zanden transport and DAC - I would bet on a very nice improvement.

Arnie

Babybear, Lloydelee21, and Himiguel,

Thank you for your feedback!

The ultra 5's under my turntable, phono stage and Tripoint Troy. Revelation! I use 5 5's under my turntable, 4 5's BMC phono stage, 4 5's under the Troy. Positioning and direction are critical. In my experience under components, threaded insert must face shelf. Impossible to judge or maximize performance of any component without the 5's.

himiguel

Hi VPN,

FWIW, I just did that with my Wilson X1s...stunning changes. I posted on whatsbestforum. Ultra V and X1s thread. Stillpoints makes adaptor threads for nearly every screw type...mine are screwed in and they are not coming out. Good luck.

lloydelee21

Owner
Hi VPN,

Thanks very much.

I would definitely give the Stillpoints Ultra 5's a try under your speakers. If they can be threaded onto your Dunlavy speakers that would be best and Stillpoints makes various threaded adapters that you can get that hopefully would fit your speakers. The weight of your speakers won't bother the Ultra 5's.

I have tried the Ultra 5's under several components (but not my speakers) and the results have been very consistent sonic improvements regardless of which component I have tried.

Hope that helps,

Arnie

babybear

Hello Babybear,

In my view (not having heard it), I believe you have one of the top three systems here at Audiogon. Congrats!

I am considering using 2 sets of 4 Stillpoints Ultra 5 with their bases under my (very heavy) Dunlavy SC-VI speakers. I currently have BDR Pucks and cones.

Do you think this would be recommented?

Thanks,

VPN

Thanks again,
Arnie

babybear

Hope you are well Arnie, the room and system are looking great! I'm going to drop you a note and try to invite myself for a listen my next trip to Austin. I'll bring a nice bottle of wine for the intrusion. :-)

Take care,

Hi Luther,

Thanks so much.

I had a great time as well and it was nice to meet John. I am looking forward to coming down to your place as well and learning more about reel to reel playback!

babybear

Hi Arnie, great listening to your system again. It is amazing when I think it can't get any better, you manage to raise the bar. Looking forward to having you down at my place.
