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.

Arnie just got back from CES with Charles. The Absolare room was the best sound at the show. I am very picky and must say that the Rockport speakers are the best I have heard. I cannot tell you how musical the system was and transparent and so easy on the ears. The best Jeff

Hi Pradeep,

That's great news about the Avior's arriving! I am sure you want to get home to get them set up and start listening to them. You will definitely enjoy them as they are wonderful sounding speakers.

Thanks very much about the Absolare preamp. It is a very purist design and doesn't have a remote control. At first, I thought that would be a problem for me but now I am OK without one. Especially given how good it sounds!!

Congrats on the Absolare preamp. A non audiophile question : does it have a remote ?
The Aviors have arrived back home. I am in NYC for another ten days :(

Thanks very much Charles,

I have heard the Absolare Passion preamplifier and the Absolare Passion 845 amplifiers matched with Rockport Aquila speakers when I visited Absolare in Istanbul, Turkey this past summer. It was really, really good. I believe they will have a very similiar setup at CES this year with both digital and analog front ends. Have a great time.

Hi John,

Thanks very much.

I did decide to go ahead and purchase the Absolare preamp. I did 3 comparisons between the VTL 7.5 Series 3 preamp and the Absolare Passion Signature preamp and every time I did this, the differences were consistent and obvious.

When I am at your place, we'll have to pick a day for you to come by here as well and do a lengthier listening session given all of the changes that I have made since the last time you did that (not counting the Christmas party).

Arnie

Hi Arnie, sounds like you went ahead and bought the Absolare...I was very impressed with that pre amp in your system! Congratulations !!

System edited: I've been evaluating some new components for the past 6 weeks which have resulted in a few significant changes to my system. 1. First and most importantly is a new preamp, the Absolare Passion Signature Balanced preamplifier. This is a truly remarkable preamp that has a very open, transparent, effortless and natural sound that takes the performance of the system with the Rockport Arrakis even further than I thought possible, 2. Echole Signature power cord with an inline Purifier module to power the Rockport Arrakis external active crossover. This power cord with inline power filtering has helped to create an even blacker background and a more organic, coherent and refined sound. 3. The use of Stillpoint Ultra SS footers under the Allnic H3000 phono stage, the outboard power supply for the MSB CD transport, the outboard power supply for the MSB DAC and under the new Absolare Preamplifier.

Hi Pradeep,

Thanks very much!

I find a glass of good red wine goes very well when I listen!

Let me know what you think about your listening with the VTL and when the Aviors arrive. They are wonderful speakers.

Hi Lloyd,

The preamp that I am auditioning is called the Absolare Passion preamp. It is made by the sister company of the cables that I use - Echole. I first got a chance to hear it when I visited Istanbul, Turkey this past summer where the company is headquartered.

Robert Harley was part of that same trip and he recently did a short blog about his visit and in the blog you can also see some pictures of the preamp as well as the amps. Here is a link:

Hi John,

Thanks very much and thanks for coming last night. Everyone seemed to have a great time. But we did order a little too much food!

Let me know when I can come by your place to listen to your system. Looking forward to hearing it with all of the new acoustic treatments. Most any time will work for me so whatever is good for you, just let me know.

babybear

The Rockport's in general have better transparency and more natural presentation. I've head the Avior's extensively, Arnie's set up a few times now and Altairs once at the Rockport facility...I do have a friend in Austin with Alexandria's, I'll go listen to them again soon...

The Wilson's, but NO MEANS are wrong. I do think they do dynamics and bass power like no other. It's really what sound and signature you prefer...these are all degree's of perfection...it's like a Porsche can corner better than a Corvette..but the Corvette has better torque and power from the starting line and the straight roads...

jfrech

Wow! Great to know you heard Babybear's system...wish i could do same someday.

What makes you think of Altairs over Maxx3s?

And what preamp is Arnie now auditioning?

lloydelee21

Hi Arnie, thanks so much for having us over. Excellent food, wine, fun and friends!

Your system has made some nice improvements, I know I only got to hear it with the others...but I could definitely hear the midrange and top end beauty. That was the best I've ever heard Rockport's sound...including the Altair's in Andy's room in Maine. These Rockport Altairs are really tugging on my checkbook now ;-) ...fabulous speakers !!

I have to assume the cabling changes and especially the preamp you're demoing has a lot to do with this beauty...

Best of everything this Holiday Season !!

Arnie,

For sure. Will do. Thanks again.

Hi Lloyd,

You're most welcome. Let me know what you hear when you put the Ultra 5's under your speakers.

Arnie

babybear

Wow! Thanks for the quick reply, Babybear! Great stuff! I realized i use HRS nimbus couplers and dampers, Artesania dampers and Auralex subwoofer isolation platform on: Transport, DAC, DAC PSU, CJ GAT and the Velodyne. Basically the Wilsons and the Gryphon Colosseum have no 3rd party isolation. The Colosseum has enormous 3" thick feet with a 2" thick methacrylate base of some sort.

And Wilson appears to use the same spikes since 1994...good ones...just wondering if Stillpoints will make the same material difference you seem to have found with your components. (I was very impressed by what Ultra SS did with Esoteric Transport...in fact, i would use the very same description you gave about what i heard with the Ultra SS and the Esoteric transport.)

And the Ultra SS/5s were primarily designed for heavy speakers...fingers crossed and thanks again!

lloydelee21

Hi Lloyd,

Yes, you are certainly correct in that I won't even try to put an Ultra 5 footer (or any other footer for that matter) under the Arrakis - not at 900 pounds for each speaker and given the substantial base and footers that the Arrakis come with.

As for the Stillpoints Ultra 5 and also the smaller Ultra SS footers - in my system they both perform exceptionally well. I have only used the Ultra 5's under my turntable and right now I am also experimenting with the Ultra SS footers under my phono stage, the outboard power supply of my CD transport, the outboard power supply of my DAC and the analog output stage of my preamp. I added one set of these footers at a time so that I can understand the impact of what each set does. With each set of these footers that I add, they have the same effect and it appears to be cumulative - increased resolution, increased focus and coherence and at the same time a greater sense of ease with the music. They also seem to increase the sense of the acoustic space that the music is played in. Overall, the performance just seems more natural sounding to me. I have been comparing them to what I was previously using - Pyon Sound Spira Ultra tuning feet. So far, based on what I am hearing, the Stillpoints Ultra 5 and Ultra SS footers are superior and by quite a bit.

babybear

Just the man to talk to!!! Babybear - i have just asked to audition Ultra 5s for my Wilson X1s...any thoughts on this? I cannot imagine you would wish to try under the Arrakis, given the base that Rockport has built under the speaker. However in my case, with the Velodyne DD18 being so dramatically changed by the Auralex subwoofer isolation platform (recalibrating after installing it meant going from volume 9 to 32!!!)...means the floorboards are singing. so i am going to try them under the trusty old Wilsons.

Any thoughts on Ultra 5s...what they do...did you compare to anything else? thanks!

System edited: I've added a fourth Stillpoints Ultra 5 footer under The Beat turntable. I've also added a Minus K BM8 vibration isolation platform under the turntable. I've added 18 pounds of ballast weight onto the Minus K platform to bring the total weight up to 129 pounds (the BM8 that I ordered has a weight rane of 90-130 pounds). This allows the Minus K to operate at its maximum. In my system, adding the Minus K under the turntable has further reduced the noise floor when listening to vinyl. In addition, performers sound more palpable, the upper frequencies have more finesse and the overall presentation just feels more effortless.

System edited: Changed the Interconnect between the Rockport active external crossover to the VTL Siegfried mono block amps powering the bass drivers of the Arrakis 2 from an Echole Obsession IC to an Echole Signature IC. The Signature IC provides deeper and more resolved bass than the Obsession IC.

Hi Aaron,

I have done the listening comparison in my room between the Platinum Signature DAC IV with the Diamond Power supply and the Diamond DAC IV (with the optional clock) also with the Diamond power supply both fed by the Data CD IV powered by the same Diamond power supply. I found the Diamond DAC IV to be (With the clock) in audio terms, a significant improvement and the Platinum Signature DAC IV is already really good. The other really significant improvement was when I auditioned the Data CD IV powered by the new dedicated Signature Transport power supply (which is a linear power supply) instead of using the transport power supply inside of the Diamond power base which is a switching power supply. Both of these are well worth hearing in your system if you get the opportunity to do so.
