Description

Decades of experimentation, since the late '60s, have taught me you're never done trying new things if you want better sound. I'm now having a serious love affair with tubes, have finally reconciled with CDs/SACDs, and am embracing all the new tools available for room measurement that never existed when I started this hobby.

In the past few years I added a ARC Ref 40 pre-amp that has tremendous spacial and textural resolution, something that was missing from my solid state front-end. I've been suffering from serious sleep deprivation since I got it. It's that good.

After many years of vinyl only (I was a diehard) I added a Marantz SA 7 S1 CD player. This was the first CD player I really enjoy listening to and I've kept it. SACD can rival vinyl & well-recorded CDs sound really good. The addition of a Lyra Etna cartridge, the ARC REF 10 phono and the TW Acustic TT however, all have added a presence and naturalness for analog playback that's simply breathtaking. +1 for Vinyl!

I can't leave anything alone. Most of the components are very heavily modified, especially the Sansui TU-717, and both the Counterpoint SA-220s which actually use a completely different circuit than the original amplifier. The first SA-20 became an NP-220 courtesy of Michael Elliott. It has Mullard brown base CV-569 ECC35s (6SL7s), CuTF V-Caps, and a 160,000 uF all-Black Gate power supply with boatloads of TX2575 resistors in all critical places. I loved the sound of this hybrid amp so much I added a second one that is almost identical. These amps are classics and the proverbial "open window" when it comes to transparency and tonal color. Too bad few will get the chance to hear these since the "retirement" of Aria Audio.

The system speakers are tri-amped Magnepan 3.6s and include Kinergetics subwoofer towers(5 10" woofers per side). One Counterpoint NP220 drives the tweets/mids, the other the 3.6r bass panels, and a recently added Krell Evolution S2250e drives the subs providing a deep and solid foundation. This system's flat to about 16 Hz.

The Pass Labs XVR-1-3 3way XO is incredibly flexible. It would have been impossible to get this tri-amped system set up as well with an ordinary XO as the Magnepan 3.6s have some funky passive XO slopes you need to emulate. I'm using it in bandpass mode. Much more transparent this way.

I ran out of wall outlets and gave up on active quad amping. I upgraded the only remaining passive tweeter-mid speaker XO in the 3.6s to something exotic - Duelund Cast caps and inductors instead of another XVR-1. It was well worth it but big passive XO parts are best broken in with a cable cooker if you want to live long enough to hear what they sound like (nothing) when broken in. Nelson, you will have to fund your own retirement plan!

All the system cabling is supported by Cable Elevators - I tried using the empty champagne bottles but the system didn't quite sound as good -- burrrpppp.

The room had a makeover with acoustic treatment. It's 13.5 x 27' and is in the basement. An RPG pro diffusor sits behind the speakers with Real Traps & GIK Acoustics along the side walls & in corners. The back wall also has an RPG pro. The speakers have been moved away from the front wall so that second relection arrival time is almost 10 milliseconds delayed from direct radiation at the listener location. This treatment work substantially improved the imaging, depth, and bass control. You just can't get good sound without paying serious attention to room acoustics.

I've finished the final room EQ on the subs using REW and the DSPeaker Anti-mode 2.0 Dual Core processor. What a great gadget! The EQ settings still need a little work below 100Hz to minimize group delay. None of this impacts the main speakers so that transparency is maintained.

Various AZ cables were added and all have been "cooked". The transformation is remarkable. I've tried other stuff and I wonder why people spend $1,000s. The power cords are LessLoss.

The system power outlets are all Hubbell hospital grade 20 amp jobs on their own lines.

Let's talk about the music. It's thrilling to listen to it. There's not enough time in the day. There's lots of immediacy a trait which I value the most, wonderful tonal color, and the sytem has a terrific sound stage with solid center imaging. Most notably, there's a sweetness and liquidity somewhat like you'll only hear from SET audio systems. Overall balance is perfect, neither warm or bright, but with power and authority.

I listen to all kinds of music, classical, pop, jazz, world, etc. and this system is very musical. I'll miss the Aleph 2s heatsinks that all ran at 125 F but the sound still warms my heart!

Components Toggle details

    • Lyra Etna
    Who knew vinyl could sound this way? Absolutely stunning. Still love it as much as the day I bought it so I got another as a back-up. On most any material, this takes my breath away. You are there.

    The 2nd replacement cartridge sounds even better.  Set up with Adjust + and loaded at 350 ohms - a bit more dynamic as you'd expect.  Oh, no, here comes the Lambda!
    • Triplanar Tonearm & Mint Protractor IV w/ VII Upgrade
    Tri Mai upgraded this baby with new wiring & bearings. It was a worthwhile upgrade at a reasonable cost. I also used a Mint Best Tractor Protractor custom measured for the arm. (I kept the brass parts on - more colorful).
    • TW Acustic Raven Anniversary
    Upgraded with Black Night copper platter, 3 motor unit, feet and the mat. This is a beautiful piece in looks as well as sound. I later changed the TW mat to a SPEC Audio AP-UDI for a little more open and dynamic presentation without losing any of the wonderful tonal color the turntable is known for.
    • Phoenix Engineering Roadrunner
    I liked the Walker Audio MC, then the Eagle motor controller with the VPI which was even better.  It didn't work with the TW's DC motor controller but wasn't needed. Not so, the Roadrunner. The Roadrunner tachometer showing speed display on the left is not for the OCD crowd as that last digit is not always a "3". Speed stability of the TW Acustic TT varies < +/- .003 over 3 minutes or so.
    • Audio Research Corp Reference 10 Phono
    Decided to upgrade the phono section and picked ARC since I liked the REF 40 Anniversary so much. After installing all new tubes, tube rolling the power supply ensued.  I liked the 6550C SED Winged Cs in the REF40, but here they were a little too soft sounding. The Sovtek 6550 WEs had a more definition, but still sounded a trifle hazy. The Shuguang KT-88 Z Treasures solved that and I finally ended up with them after about 300 hours of listening. A few signal path resistors have been upgraded with TX2575s. Very nice.
    • Luxman D-10X
    Really enjoying this CDP.  Checks all the boxes and is just a wonderful listening experience on all kinds of music.
    • Marantz SA 7 S1
    The first CD player I heard that makes beautiful music! A good SACD is simply stunning and rivals vinyl although they don't sound the same. Has a little more clarity if you ground it, short the digital clock input & put a copper sleeve on the power cord against the unit.
    • Sansui TU-717
    Mint condition with highly modified with Black Gate caps throughout, Schottky rectifiers and more. This sounds nothing like stock thanks to Stereo Surgeons and an APS-9 antenna & invites serious FM listening. Too bad there's not much worth listening to.
    • Antenna Performance Specialties APS -9B
    Has a Channel Master 9537 rotator, a Ken Wetzel low-loss high performance balun & 57 feet of RG-11 (the fat stuff). Routing it was a PITA! Using FMFool.com to find the exact channel directions. This was originally installed by a firm who also did work for the US government military.  I had no doubt when I got the bill.
    • Audio Research Reference 40 Anniversary
    Sounds as good as it looks! Favorite tubes are the 6550C Winged "C"  and the stock Sovteks 6H30s.  Forget the expensive DP version.  All tubes are matched within 2% with the Amplitrex AT-1000. A very few signal path resistor mods here too.
    • Magnepan MG-3.6R
    These sound nothing like stock because much of the original has been replaced. They have been completely re-wired with cryo Neotech 6'9s copper, have Vampire BPHEX solid copper binding posts, no fuses and no "socks" underneath the grill cloth. Very transparent and dynamic. Internal and external stock crossovers are gone....
    • Custom 3.6R Crossover Duelund Cast, etc.
    Replaced stock internal mid/tweeter XO with outboard box containing Duelund Cast & V-Cap caps and inductors. Hello reality!
    • Mye stands 3.6s
    More heavy metal! If you have Magnepans these stands make an audible difference and are well worth the money. These have been modified by firmly anchoring the rear mid-speaker frame braces to the speakers instead of their wood grill frames.  This allows better transmission of unwanted vibration from the speaker to the stands and into the CMS LS .8 speaker feet that are mounted under the steel frame bases.
    • Kinergetics SW-800
    Five 10" drivers. Woof , woof, woof. Too bad they don't make these anymore. REW software confirms they have measurable flat response to 15 Hz. Good match with the Magnepans.
    • Pass Labs XVR -1, 3 Way
    3 way XO w/ millions of settings used in band pass mode. You can change slopes, XO points, and Q settings & compare results almost on the fly.  Over 200 parts changes were painstakingly made and auditioned in 30 iterations over an 18 month period!   Left and right channel amp outputs balanced via the dials with a DVM to within .1mV to precisely balance the soundstage. Yes, it matters.
    • Counterpoint NP220 Platinum Plus #1
    One-of-a-kind amp from Mr. Elliott with an entirely different circuit than its namesake, along with several parts upgrades from me. For the 3.6 panel tweeter/mids: It's a platinum premium NP220 amp w/ ECC35 CV569 Mullards (fantastic and rare tubes),CuTF V-Caps,a Plitron choke & a main supply w/ all Black Gates totalling 160K uF coupled w/ solid high-grade copper buss bar. Critical resistors are all TX2575 naked Vishays & Cardas internal wiring. It even has damped circuit boards! Very sad you've retired Jack you will be missed!
    • Counterpoint NP-220 Platinum Plus #2
    Liked the first one so much, needed another one of a kind to assure the Magnepan's sonic coherence. This one drives the 3.6 Bass panels. Black Gates for the Power Supply no longer available so used the biggest Siemens Epcos Sikorels that would fit. These caps are just as famous at the BGs and maybe even better sounding, but very hard to find. Terrific build work done on a complex circuit topology by Music Technology. B.T. described the sound as "lovely".
    • Krell Evo S2250e
    Perfect amp for the subwoofers with 500watts/ch - way more than needed. The bass on this system is subterranean - flat and powerful, but not boomy to below 15Hz. This amp is well-built, doesn't run hot, isn't that heavy and really has the bass control Krell is famous for. Sorry, no class D for me.
    • Acoustic Zen Absolute Copper
    Trying to describe the sound of these is almost impossible. May be a touch forward sounding.
    • Acoustic Zen Hologram IIs
    All speakers now wired with AZ. With a tri-amped system there is lots and lots of cabling. Don't like it? Just turn the lights off!

    I also tried Duelund DCA DCA16GA X 2.  It's very nice an inexpensive to boot.
    • Power Cords LessLoss, Neotech & Oyaide
    One LL feeds all the front end components via a Furutech etp-60; the others feed the two custom Counterpoint  amps. Neotech NEP-3003 feed the CD/SACD player and phono amp. The Oyaide Tunami V2 feeds the XVR-1-3 way
    • Other room treatments Real Traps & GIK Acoustics
    Besides the RPG Pro diffusors, Real traps panels for first reflections & GIK corner traps. Tightened up the bass & really helped center the sound stage as the room is not symmetrical. Pic shows the completed room with panels mounted.  Each one of these was placed and then REW was run to check frequency response, group delay  and decay.
    • Critical Mass Systems Center Stage V2 .8 & 1.0 Component Feet LS Series Loudspeaker Feet
    I am in the process of upgrading the CMS 2s footers to CMS 2Ms.  I really didn't want to do this, but the 2MS are significantly better in all sonic aspects.

    Now have 11 sets of these under almost everything. .8s are under the ARC power supplies and the Sansui tuner. 1.0s under everything else except the 2 Pass Labs XO power supplies where I'm using Sound Damped Steel. Noticeably larger and more continuous soundstage, much better 3 D images, better attack and decay, and improved tone / harmonics. I was quite amazed by this...and the money spent. Subsequently, added LS .08 loudspeaker feet with even more of the same "goodness".
    • Equi=Tech 2RQ
    Balance Power unit (front end - not amps).  Have tried various power conditioners before and didn't care for them.  Read the technical info. This is something else and well worth it. The result is dead silence and a noticeable sense of increased interior spaciousness and depth.
    • DSpeaker Dual-Core 2.0 Antimode

    Used with REW and ONLY in-line on the subs where it'll do no harm.  I upgraded the power supply to an standard LPS type and got rid of the wall wart.  As the system's improved I've tended to bypass this unit as it's not all that transparent.

    .


    • REW Room EQ Wizard
    Used in conjunction with the DSPeaker Antimode to achieve great room response in optimized frequency & time domain. This program is really quite amazing but takes some time to learn how to use.
    • Leica Disto - Laser Measure E7400X
    Want great soundstaging? Measure speaker distances to the listening position within 1/10".
    • Audiodharma Standard Plus 3.5 Cable Cooker - Smokin'!
    I love this thing and use it a lot.  You too can be a cook! Myles Astor is right. You need one. Noise floor drops, more detail and a little more space. A very worthwhile upgrade and one that'll make you stop chasing cables. Recooking every 4-6 months brings back transparency. I also use this to burn in all my mod parts before installing them.
    • VPI HW 16.5 Rec Clean - Foaming Action
    Yes, it's the VPI but... with secret, proprietary, organic rose cleaning solution developed in the French countryside. Wonder why this stuff keeps evaporating? Good for a pre-clean on older albums.
    • KL Audio KD-CLN-LP200 Ultrasonic Record Cleaner
    Use the VPI for the heavy scrub first and then this baby as follow-up. Total cleaning and drying time about 15 minutes per record.
    • KL Audio Filter System
    Added tubing, a pump, and a FlowMax .35 micron pleated filter canister to my KL Audio record cleaning machine.  Run the pump and filter to clean the KL tank water for ~ 10 minutes after cleaning a dozen records or so. Can measure water "dirt" with a total dissolved solids meter (TDS). They're cheap too. Only I would ask for one for my birthday. No wonder my family doesn't talk to me.

    Ack!!! Just saw a .2 micron filter with 40% more filtration for $5 more.  No COVID-19 in my RCM waste water now.
    • Hi-Fi Tuning The Supremes
    These are in every piece of equipment. Nice step up from the originals.
    • Feickert Adjust + Cartridge software
    For cartridge azimuth adjustment, the end results are a more coherent sound stage. The software overloaded my computer soundcard so I had to pad down the output of the phono preamp output. A little fiddly to run all the cartridge position set ups. The standard bubble level's worthless. It's well worth the time and expense!
    • Herbie's Audio Lab HAL-O III Stabilizers
    Probably better than those rubber/sorbothane things. Cleaned up the sound of the REF40 and Phono 10 a bit when used on the PS 6550C tubes and 6H30s.
    • Amplitrex AT-1000
    Best new tester for tube matching. You can do curve tracing matching mu and Gm across a range of voltages with this hooked up to a laptop in computer mode. I have enough matched tubes to last at least 20 years.  Hope tubes don't turn out to be old technology.....
    • Get away Vehicle Richard Sachs custom
    Forget audio. Not as fast anymore and getting slower, but has Sachs appeal!

    I take obsessiveness seriously.  When I was younger (a couple of years ago??!), the tires on this bike were woven silk and glued on the rims.  Now, that's old technology, so I've upgraded to clinchers.

Barry,

Great system! I am sure it sounds very realistic!

I think we are like minded: (i) I am currently in the process of having new external crossovers built with Duelund CAST components, (ii) have just bought a Pass XRV-1 and a second pair of Krell fpb 750mcx to biamp my Dunlavy SC-VI, which I will use to drive the four 15" woofers, and (iii) I am playing with Dirac Live measurement and correction.
Cheers,

I also owned a beautiful 1956 2door Chevy BelAir when I was 18. Dropped a Vette 350/350 horse small block in it. Had a 4.11 rear. Used to break speedometer cables. Got about 11/mi/gallon when I got on it - a real monster. That's how I got into Audio. Someone stole it and I took the insurance money and bought my first stereo. Probably why I can't stop modifying things now.

barrysandy

Boy that brings back the memories. My brother and I used to do all of the maintenance on our Mustang, including tune-up, brakes and even front ball joints. Today, the cars are built much better and really last. Unfortunately, you have to have a EE degree in order to repair anything under the hood. I'm not even sure how to fill the wiper fluid canister.

I'm old enough but don't remember that one. Do still dream of the 426 Chrysler Hemi's and always wanted a Charger.

If you can find a used REF 150, I'd go for it. Pricing appears to be around $8.5K. I considered buying a pair of 150's but didn't want to spend that much. I'm sure you'd be very happy.

I was lucky to find my second Counterpoint NP220 that I upgraded last November. There were only about 50 of these built between 1999 and early last year when Michael Elliott call it quits again and retired.

Glad i was able to help with the 5SE!

barrysandy

Hey Barry, are you old enough to remember the Vette's' Z-88 semi-hemispherical engine from back in the late 60s and 70s?? That machine was one babe magnet. I think gas was less than 40 cents/gallon. I tooled around in a convertible white 68' Mustang. Believe or not, I had to put some of the babes in its little trunk. Best looking hunk of junk on the market.

BTW, I've got my eyes peeled for a pre owned ARC Ref 150 amp to come up on the market. It should mate very well with my Ref 5 SE pre. It's hard to describe or explain the natural synergy using all ARC gear. It just works seamlessly together.

From what I've been reading, ARC is using a lot of Ref 40 technology in their current Ref equipment line, like my upgraded Ref 5, now SE. So, thank you for funding the R&D that went into my Ref 5 SE. ;>')

The ARC Ref 40 was love at first sight & listen. My wife thought I was crazy spending so much but I didn't care. I had no idea what a treat I was in store for. Never heard anything like it. I HAD TO HAVE IT. More like a 1965 Corvette Stingray convertible 365/327 Nassau Blue - a friend of mine had one of these.

http://www.youtube.com/watch?v=DDTKU9ximas

Each Counterpoint has 420 watts/ channel into 4 ohms with lots of headroom to spare. Every resistor, every capacitor, the wire in the amps, is all hand selected. The power supply for #1 with Black Gates FK caps is 60% bigger than stock and cost $4K alone just for the caps. #2's power supply with the Sikorels is 30% bigger than stock. These amps would cost upwards of $25K based on the parts quality and expense but who cares. What matters is they sound incredibly real. Actually 0 to 60mph,... fast enough. Their virtue is naturalness and immediacy more than speed. Vocals are to die for. Thanks for your kind words Bifwynne. Now, lets go buy that Vette!

barrysandy

Great system!! Wow what a rig. I LUV the ARC Ref 40. I looked at all of the pics, but the amps were really cool. They look like dual supercharged Z-88 "Vette" engines. How many horsepower do these monster deliver? How many seconds to get from the 0 to 60 mph? ;>')

System edited: Place for bass! Finally got around to adding a great subwoofer amp - a Krell Evo S2250e of course with 500watts/ch. Also got a Rythmik Audio 15" powered sub I placed at the back of the room to smooth out the bottom end. So many spots to try and so many amp settings will take some time. Back to fiddling with the Pass Labs XVR-1-3. Using one of the 3-way units in bandpass mode eliminates some filters/buffers and makes the whole set-up much more transparent but the frequency response has changed a bit so needs some sorting out.

Owner
System edited: I've been very busy! Since the start of 2013 have added another Platinum + Counterpoint NP-220, this time for the 3.6 bass panels replacing modded Aleph 2s. Countless hours of measurements using the DSpeaker 2.0 Dual Core Antimode have almost optimized the room response (see pic). Low-end looks lumpy in the pic but doesn't sound that way and I can't hear a big difference between DSP equalized in or out (Maybe I should buy some audiophile Monster Q-tips??!!!). Now, my friends at Pass Labs have shown me a new way to hook up the XVR-1-3 that bypasses some internal circuitry for better sound. I'm finally getting close to pulling the trigger on a new subwoofer amp. I still have some room modes below 200Hz (with DSP-equalization out) so I'm adding a Rythmik Audio F15HP at the back of the room to see if I can further smooth things. Probably more than a little crazy as I already have the front pair of 5X10" sub towers but that's the whole point of "All Out Assault"!

Barry, No preferred setup to suggest. I'm using an entry level Squeeezebox. I've found that I listen to my Squeezebox 85% of the time that I listen to music. It's the convenience thing. For critical listening, I play cd's...for special occasions, I play vinyl. I've been procrastinating for a few years now on getting a serious DAC and moving to high-end computer audio & streaming, since that's where I spend the overwhelming majority of my listening time. I found that I listen to a lot more music since I got my Squeezebox a few years ago. The convenience is impossible to ignore. Oh, and it sounds good too.

Not yet although some music I've found (weird Traditional Chinese instruments) is only available via download. Do you have a preferred set up Mitch?

I am looking for another Counterpoint amp to match the one I have. I had a bad dream last night that I wanted to put TX2575 resistors in the Ref 40! let's hope that doesn't happen.

Barry, have you considered computer audio or a streaming device with a DAC?

Mitch - Rent out the loft. Use the proceeds to buy the Ref 40 that's now listed on Agon for $11.9K. Seriously, thanks so much for the compliment. If you're ever in the Philly area drop me a note and stop buy for a listen. I can't believe I never knew what I was missing for the past 3 decades listening to different ss preamps. As likely, it just took this long for a major tube technology breakthrough. The Ref 40 is it. The Maggies too are so modded, they sound nothing like stock, more like electrostatics with body, not that insubstantial hollowness some are prone to.

barrysandy

Owner
Hi Bob. Looks like you've been through quite a bit of equipment yourself based on your Agon review. I especially like your fish tank thread as I've always wanted one! Wow that's a big one and I don't mean the fish. The Pass are the best sounding and most flexible SS analogue crossovers available. Some have questioned my use of ss with tubes, but I really can't hear the sound of them and I have owned 2 others which had an audible electronic signature even though I modded the heck out of them.

barrysandy

.
Barry, I keep coming back to this page and looking at your Ref 40th Anniv preamp paired with Maggies and it's killing me.

I think I hate you ;)

Please remove the photos so that I don't have to look at this stuff. I salivate at the thought of hearing your system.

When I grow up, I want a Ref 40 and Maggies.

The end.

Just saw your system and I really like what you have put together. I bet the maggies with your custom crossovers sound incredible. Very nice.

Hi Mitch! The Aleph 2s are class A. This is an older pic. The Threshold was my subwoofer amp for the Kinergetics. I'm trying to figure out what to do for the subs. I'd like the amp to match the NP220 but I can't find a modded Counterpoint in decent condition.

barrysandy

Great system.

I see you have the Alephs for the bass and the Counterpoint for the mid-tweets. What do you use the Threshold for?. Are the Alephs class A ?

System edited: Work now includes extensive room measurement to see if I can fine tune the crossover and speaker placement. It actually looks pretty good as adjusted by ear and will only need modest tweeking not "digital re-engineering" and another component in the signal path. This thing is really fun to play with. See the pic under Dspeaker Tweak.

System edited: Did the last bit of tuning of the passive tweeter/mid XO in the 3.6s using the cable cooker to burn in the big Duelund caps and inductors. Huge difference in sound as everything opened up. Did all the cables too. Changes were not subtle - bigger soundstage, more clarity, more texture and body with better instrumental decay. Heavenly!

barrysandy

What an extraordinary long-term labor of love the development of your system has been! I'm sure the results are spectacular. Enjoy!

Best regards,

almarg

Hello Barrysandy.
I love your system. I also biamped a pair of 3.5s plus stereo subs with excellent results.
I am currently using a similar approach with biamped 20.1s. I have also spent a lot of time tweaking my components. Its certainly more fun and satisfying DIY and also significantly cheaper than buying the next component of the month.

Owner
Yes the XOs are custom built. Boxes custom madefrom Carolina Wood Designs. Wiring is Neotech cryo 6 9s copper directly to the speaker tabs using Furutech gold plated push on connectors. Tried a strand of silver wire too -- hated & removed it. Binding posts are solid copper Vampire BPHEX. The 2 series mid-range inductors are Duelund Cast as is the tweeter series cap. That cap weighs more than 2 lbs! The parallel cap and inductor are V-Cap and Erse. The new XO parts removed a fine layer of haze and provide almost bowling alley depth of field compared to stock. Stock parts actually don't sound too bad but with this XO you hear absolutely everything that was recorded too. Big sonic improvement @ big cost and you need good recorded material. With the combination of this ARC Ref40 preamp and the new XO I've noticed that some multi-track recordings have strange muddled spatial presentations I never heard this with either the Pass Labs XP-20 or the X0.2 line stages that are solid state.

barrysandy

Awesome system Barry. I love the fact you don't have the flavor of the month and keep your gear. Also, I am very big in modifying my gear when I can. Did you build the speaker X-overs? Did they make a big sonic improvement?

Owner
Hi Steve thanks for your kind comments. You've got quite a nice system yourself. Sometimes changing parts does not always yield better sound. It's generally a heck of a lot cheaper if you start with the right piece of equipment. I'm just about done with all this.
