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

    • TotalDAC D1-Streamer MK2
    I just had my TD D1-Streamer upgraded to the latest version TD D1-Streamer MK2 (November 2022).

    In my setup, I use the TotalDAC D1-Player with its silent NAS using solid state drives to store all of my digital music files. Both the D1-Player and the D1-streamer are connected to a Belkin router and I control music selection using an IPAD mini running Roon remote (The D1-Player runs Roon Core and the TotalDAC D1-Streamer is a certified Roon end point).
    • TotalDAC D1-Digital Reclocker MK 2
    I have just had my TotalDAC D1-Digital Reclocker upgraded to the new MK 2 version (November 2021). The Digital Reclocker MK 2 sits between my D1-Streamer MK 2 and the D1-Twelve mono DAC's in my digital front end.
    • TotalDAC D1-Twelve MK3
    I just had my TD D1-Twelve upgraded to the new MK3 version (November 2022).

    The TotalDAC D1-Twelve DAC mk3 is composed of two mono bloc DAC's and a specialized re-clocker, so it is a 3 box system. The D1-Twelve DAC mk3 in combination with the D1-Streamer can play 16 or 24 bit format and 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz, and DSD sampling rates.
    • TotalDAC USB Gigafilter
    I have upgraded the TotalDAC USB Cable that connects the TotalDAC server to its internal re clocker to the new TotalDAC USB Gigafilter cable.
    • TotalDac D1-Player
    I have just had my D1-Player upgraded (November 2021) with a custom Live Power supply by TotalDac. The linear power supply also does filtering and cleansing of the Ethernet signal. The connection path for this is an ethernet cable between the NAS and power supply and then another ethernet cable from the outboard power supply to the router. In addition, the NAS is running Roon Core and since the TotalDAC D1-Server is a certified Roon endpoint, I am now using Roon Remote on an IPAD mini and using Roon as my music player (replacing MPAD). The D1-player can also be used as a upnp/dlna server. i am using a Nordost Odin 2 power cord on the D1-Player.
    • TotalDAC D1-Switch
    I just added the new TotalDAC D1-Switch to my digital front end. The switch connects to my Belkin router and now the TD D1-Streamer mk2 and the TD D1-Player connect to the the D1-switch instead of the router. This provides a very significant sonic improvement. I use a Nordost Valhalla 2 power cord for the D1-Switch.
    • Totaldac Live Power supply
    I just added the TotalDAC Live Power supply. This version can be used to provide power to my complete TotalDAC D1-Twelve digital front end - the D1-Streamer, the outboard reclocker and the 2 DAC's. I use a single Nordost Odin Gold power cord for the Live Power supply which is plugged into my Shuyata Everest power conditioner.
    • Nordost Odin Gold power cord
    I am now using a Nordost Odin Gold power cord for my TotalDAC Live power supply. This replaced the already wonderful Nordost Odin 2 power cord.
    • Nordost Valhalla 2 Ethernet Cables (2)
    I am using 2 of the new Nordost Valhalla 2 ethernet cables. The first one connects between the TotalDAC D1-Player and my Belkin router and the second one connects between my TotalDAC D1-Streamer and my Belkin router.
    • Audio Quest Diamond Ethernet Cable
    The AQ Diamond ethernet cable is used to connect the TotalDAC D1-Player to my TotalDAC NAS. This is used for the "dirty" ethernet connection.
    • Paul Hynes SR7 Linear Power Supply
    I have am using 2 of the Hynes Sr7 Linear power supplies. One is used to power the Belkin Router and the second one is used to power my network switch. Both of these replaced the stock switching power supplies that came with the Belkin router and the network switch.

    Both of these power supplies have had the grounding update done to them and are connected to one of my Telos GNR ground noise reducers.
    • Nordost Valhalla 2 Power Cord
    I use 4 Nordost Valhalla 2 power cords in my system.
    I use one of them to power the Beat SE outboard power supply.
    I use 2 of them to power the CH Precision P1 boxes (not the CH X1's).
    I use one of them to power the Nordost QB4 power strip from the Shunyata Everest 8000 power conditioner.
    • Nordost Odin 2 XLR IC
    Nordost Odin 2 Balanced IC's from the TotalDAC D1-Twelve mono DAC's to the CH Precision L1 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.
    • Nordost Odin Gold Power Cord
    I use a Nordost Odin Gold power cord with a 20 amp IEC connector from a wall outlet to power the Shunyata Everest 8000 power conditioner.
    • Nordost QBase QB4
    I am now using a Nordost Qbase QB4 power distribution box powered by a Nordost Valhalla 2 power cord from the Shunyata Everest 8000 power conditioner.
    • Shunyata Research Hydra DPC 6 V3 power conditioner
    I have now added the Shunyata DPC 6 V3 power conditioner for my computer based audio gear. I have my TD D1-Player, my network router, my network switch plugged into the DPC 6. I was very surprised by the improvement the DPC6 V3 made in my system sonics.

    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.
    • Minus K BM-8 Vibration Isolation Platform
    A BM-8 Minus K vibration isolation platform placed underneath
    • Nordost Valhalla 2 Power Cord
    This Valhalla 2 power cord is used on the outboard power supply for The Beat SE turntable. This is plugged into the Nordost QB4 power strip. The QB4 is powered by a Nordost Valhalla 2 power cord which 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.
    • Lyra Olympos SL
    The Lyra Olympos SL MC cartridge is now mounted on my second Schroeder LT tone arm with Magnesium arm tube. A truly great sounding combination.
    • 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 P1 phono stage
    I have now upgraded my CH P1/X1 phono stage to the CH Precision True Dual Monaural phono stage. This consists of a P1 for the left channel, a separate P1 for the right channel and 2 of the optional CH X1 power supplies - one for each channel. As good as the stereo P1/X1 was, the true dual monaural P1 phono stage is something very special to hear.

    June 29, 2021 Update: I just replaced the umbilical power cords from the X1 power supplies to the CH P1 phono stage with a new umbilical that Steve worked on with Nordost. A very significant sonic improvement.
    • Nordost Odin Gold Power Cords
    I am now using two of the Nordost Odin Gold Power Cords to power the two CH Precision X1 external power supplies for my CH Precision P1 true dual monaural phono stage.
    • Nordost Odin 2 XLR IC
    I am now using Nordost Odin 2 balanced IC's between the CH Precision P1 true dual monaural phono stage and the CH Precision L1 true dual monaural preamp.
    • Adona Zero GXT Turntable Rack
    Finished in black with a top shelf of 27" in width.
    • Telos Ground Noise Reducer
    I have added two of the Telos GNR (Ground Noise Reducer) units to my system. One of the GNR's is connected to all of my analog front end electronics and the second GNR is used for my digital front end components.
    • Computer Audio Design (CAD) GC3 Ground Controls
    I am now using 2 of the CAD GC3 Ground Controls. One GC3 is used for signal ground with each of my CH Precision M1.1 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 have added the CAD Ground Control Reference (GCR) to my system. This is used for signal grounds for my front end components (CH Precision P1 phono stage, CH Precision L1 line stage and my TotalDAC D1-Twelve digital front end) and also 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 L1 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 now using 2 pairs of Nordost Odin Gold speaker cables  to bi-amplify the Rockport Arrakis 2 speakers.These replaced 2 pairs of Odin 2 speaker cables.
    • 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 added 4 of the Furutech GTX/NCF outlets with the GTX outlet Frames and the 105D NCF Carbon Fiber outlet covers. These are used for each of my CH M10 mono block amps and the Rockport Arrakis 2 outboard crossover.
    • Furutech NCF Booster
    I have added three of the Furutech NCF Cable Boosters after some extensive auditioning. I have one of them under the Odin Gold power cord for the Rockport external crossover (IEC end), one under the Odin Gold PC for the TotalDAC Live power supply (IEC end) and the third one under the Odin 2 power cord for the TotalDAC D1-Player (IEC end).
    • REL Acoustics G1 sub bass system Six Pack
    I am now using the REL G1 sub bass system in the REL Six Pack Configuration. The Six Pack Configuration is 6 of the REL G1 subs configured as 2 sub towers of 3 G1's each. One stack of three G1's for the left channel and one stack of three G1's for the right channel. The bottom G1 of each stack is connected to an M10 amplifier that powers the bass drivers of the Rockport Arrakis and the two G1's that sit on top of that stack are daisy chained together. I am using the REL designed Bassline Blue sub cables to connect all of the subs as required. Each of the stacks is located to the outside of the Rockport Arrakis 2 speakers and just about flush with the front baffle of the Arrakis using the same approximate toe in angle as the main speakers.

    To power all of the G1's, I am using 6 Nordost Tyr 2 power cords and 2 custom versions of the Furutech e-TP60 power distributor that uses Furutech GTX-D NCF (R) outlets replacing the stock outlets. I am using 2 Nordost Odin 2 power cords from the wall outlets to each of the Furutech e-TP60 power distributors.

    The REL G1 six pack replaced my previous 2 REL Studio III sub bass systems. 
    • Blinn Double wide component rack
    Blinn double wide component rack with 3" thick walnut stained maple shelving.
    • Silent Running Audio (SRA) Virginia Class amp stands
    I am now using the superb SRA Virginia Class amplifier stands under my CH Precision M10 mono block amplifiers. I also am using the HRS Nimbus footers (1.5" height version) under the M10 amplifiers.
    • HRS SRX with M3X2 isolation base
    I have added 2 of the HRS SRX amp stands with the M3X2 isolation bases with G7 footers, These are for the power supplies of 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.
    • Loricraft PRC 4 Deluxe RCM
    Loricraft record cleaning machine that replaced my Audio Desk RCM. I liked how easy the Audio Desk RCM was to use, but after having to replace it 3 times due to defects I decided it was time to replace it. The Loricraft PRC 4 Deluxe seems to do at least as good a job at cleaning and perhaps a little better using the AIVS fluids.
    • 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.

Thanks zephyr,
If you are ever in Texas let me know and perhaps we can do some listening.

Arnie,...sorry for the delay in responding and thanks for the background on your decision to move forward with the REL 6-pack.. Your room and setup like Mike L's and a couple of others is that perfect combination of beautiful room, purpose-built for audio and an insanely great system!  You are very fortunate and have one kick-ass and musical setup!

Hi Zephyr,

I have had 2 REL Studio III sub bass systems for the past few years and I really liked what they did sonically. Earlier this year I had an opportunity to visit with someone who had the REL G1 "sixpack" setup in his system that uses Rockport Avior speakers. His room was about the same size as mine. I am very familiar with how Aviors sound so I was quite surprised by how realistic his system sounded and how it was able to pressurize such a large room when the REL G1 "sixpack" was engaged (as I iistened to his system with and without it). I had some discussions with REL after hearing this and I ended up moving forward. I am very happy that I did.

Arnie,

I meant to ask you last year....what led you to go with 2 x 3 G1 MkIIs as opposed to one per side (G25 or G1)?

This week Steve Dobbins visited me and installed a second Schroeder LT tonearm with Magnesium arm tube on my "Beat" turntable. This particular LT arm was my previous LT tonearm with wooden arm tube that Steve upgraded for me to the Magnesium arm tube version. I have the Lyra Olympos SL cartridge mounted on this particular arm. I have never heard the Olympus SL sound this good before - it just has so much more life and energy and with that magical midrange it is a joy to listen to with the LT Magnesium warm.

Hi Altoman,
Thanks very much.
In my listening in my system, I don't find that the Totaldac D1-Twelve setup that I have lacks any "liveliness or jump factor" at all. I continue to be impressed with how much I enjoy listening to music via the totaldac.

babybear

Hi Arnie. Your system is to die for. Congratulations. I am interested in the totaldac products, and I am curious as how it handles wide dynamic swings in the music.  Do you find it lacks "livliness" or "jump factor". Thanks

altoman

Hello Arnie,

Thank you!

Your description is very clear,  and better than any scoring.
Cheers,

Vicente

HI Vincente,

I guess the best way to state for me is that if you have both an L1 and a P1 and a single X1, the choice would be between dedicating the X1 to the L1 or to have 2 regulator boards and share it between the 2 components. Which one sounds best in your system would be up to you to decide. 

As for scoring, I don't like to do that. Instead, here is the description from my listening notes of what the X1 does for whatever component it is connected to and hopefully that helps you to better understand the value of the X1 in your system:

-       An even better bottom end foundation to the music

-       More body to the performers

-       An increase in soundstage depth and front to back layering of the performers within the soundstage

-       A greater sense of ease and flow to the music


babybear

Hello Arnie,

Thank you for taking the time and sharing!  This is quite useful.

So I learn that in your experience, in terms of upgrades, if you someone has only one X1, use it dedicated only to the L1, don't use it with the P1, and don't share with the P1. 

If you don't mind me asking one more question, If you were to give a 100 score to a L1 with dedicated X1, which score would you give to a L1 without X1?

Cheers,

Hi VPN,
Thanks very much. Yes, the CH Precision components really surprised me in how good they are. 

The question that you ask is a very good one so I will do my best to answer it. 
When I did my in home auditioning of the CH gear, I had a single L1, a single P1 (phono stage) and a single X1 with dual regulator boards. So I was able to listen to the L1 (your option A), the L1 with a dedicated X1 (your option B) and both the L1 and P1 powered by the same X1 using both regulator boards. 
Even without any X1's involved, the L1 and P1 are superb sounding components. As I went through the various configurations that I tried, the best sound from my system was with the L1 powered by the dedicated X1 (your option B) and the P1 using its internal power supply. The next best sound was using the dual regulator boards of the X1 to power both the L1 and the P1. If I had to speculate as to the sonics between your Option B and Option C, I would guess that Option B overall would be better sounding because of the sonic improvements that the dedicated X1 brings to the table. However, the advantage of Option C is that it would also sound spectacular, and you can just add either one X1 or two X1's down the road. 

Hope that helps.
Arnie

babybear

Arnie,

Congratulations!  From your comments, the CH components seem like a wonderful upgrade!

Regarding the CH L1, I understand there are several configurations:
A - L1 Dual Monaural
B - L1 Dual Monaural + X1
C - 2x L1 (True Dual Monaural)
D - 2x L1 (True Dual Monaural) + X1 (two regulator boards)
E - 2x L1 (True Dual Monaural) + 2x X1 

You ultimately decided for option E.  I wonder if you compared options B and C, and which one was better.

Thanks,

Hi Mike,

The Schroeder LT arm with the Magnesium arm tube is exactly the same arm as the standard LT arm with the wooden arm tube except for the difference in the arm tube material. Everything else is identical. We were able to do a direct comparison of the 2 versions of the arm in my system since the LT magnesium version was a brand new arm. We did the comparison with a Lyra Etna SL cartridge. Here is what I wrote from my listening notes: "The LT arm with magnesium arm tube is magnificent. As good as the stock LT arm is (and it’s superb), this arm is a definite step up. We listened to the LT Magnesium version and then went back to the LT Wooden version and the difference was quite remarkable. The LT Magnesium version has a more lively, dynamic, and resolving sound with more air around performers than the wood arm tube version. There was better overall clarity and the bottom end was punchier and more textured with the Magnesium version. When we put the wooden arm tube version back and listened with everything else being the same, in comparison, the sound became somewhat thicker, slower and “warmish” in comparison. This was all very easy to hear and not subtle at all."
There wasn't anything that I heard that was negative with the LT magnesium version. - it was just better. I am having my LT with the wooden arm tube upgraded to one with the Magnesium arm tube as well. Hope that helps.

babybear

Curious if you could describe sonic differences of the original Schroeder LT to the new design with magnesium arm tube?

mikeba316

Simply amazing....I cannot believe you added sub towers (2 x 3) to that already amazing system.  That must hit the foundations of the house (!) with great sounds.  When will you post new pics?   You've been very busy :-) !!!

I have done a few upgrades over the past 5 months.
1. The TotalDAC D1-Server has had 2 hardware upgrades done to it. The first one modified both the D1-Server and the outboard re clocker unit as to how electric power is handled within those units.
2. A second outboard power supply (26V) was added to the D1-Server to power the cubox micro computer inside of the server leaving the original outboard power supply to now just power the audio circuits inside of the D1-server.
3. I added a REL G1 sub bass system called the "G1 Six Pack". This consists of 6 of the REL G1 sub bass systems stacked in two columns each of which has 3 REL G1's. The G1's were designed to be able to perform in this type of configuration and are daisy chained together. Each of the G1's is adjusted individually as to its frequency roll off point and its gain. They are located to the outside of each of the Rockport Arrakis 2 speakers and just about flush with the front baffle of the Arrakis speakers.
4. I added a new version of the Schroeder Linear Tracking tonearm. This one has an arm tube made from magnesium instead of wood.
5. I added a Lyra ETNA SL cartridge.

All of these changes have made a very nice sonic improvement to my system.
