Description

Speakers are Focal Grande Utopia EM in black finish

Analog music sources, Technics SP10 MK3  with two Kuzma 4 Point 14" arms.  Koetsu Blue Lace on one and Air Tight Opus One in the other.   Studer A820 half track tape machine with three sets of cards, each rebuilt by Studer electronics experts so I can compare upgrade performance.

Digital music source is Aurender W20 Special Edition into Soulution 760 LEEDH.  THe best input for music so far is Purist new USB cable and AES/EBU close second place.

Soulution 725 preamp, Soulution 755 phono stage Soulution 760 LEEDH and Soulution 701 mono block amps for electronics.  See image posted Nov 18, 2022 to see how it looks.

Cable is 100% top tier Purist Audio design.  All latest 35th Anniversary,  all ten AC cords are the new Purist 35th Anniversary AC.

My space is 18 X 31 and acoustically treated with RPG panels, tube traps and fiberglass acoustic treatment over triple reinforced walls and ceiling. The floor is lamination beams over steel plates to concrete pier and beam.  Two sheets of 5/8 epoxy lamination sheets make up the floor with two inches of concrete topped with India multi color slate.

Whisper Wall rail system and fine textured acoustic cloth covers the work, making  everything appear as a normal room of painted sheet rock or decorative cloth covering.

The room acoustics were conceived by RBDG and the entire space was torn out to bare dirt under the foundation and bare studs in the walls.  The combo of all new electrical and acoustical treatment resulting in best sound I’ve ever had.

    • Focal Grande Utopia EM
    The best offering from Focal, shown with Stillpoints Ultra 5. Ultra 5 was an amazing upgrade for the speakers !
    • RPG Acoustics QRD 734 (variation)
    On front wall, now obscured by acoustically transparent cloth, is floor to ceiling RPG (similar to QRD® 734) in foam, so it's partially absorptive.
    • Studer Studer A820
    Found a near mint A820 at a production studio in Illinois.  I was so excited about it's condition I had it driven here in the back of an SUV, covered with moving blankets.

    Head block sent to John French and all cards at Soren Wittrup who worked for Studer.  This is the machine I spent more than a decade searching for.
    • Technics SP10 MK3 Rosewood with Stillpoints Ultra 5
    Technics SP10 MK3 Panzerholz + Rosewood shown with Stillpoints Ultra 5
    • Technics SP10 MK3 Panzerholz + Ebony
    Technics SP10 MK3 Panzerholz with African Ebony lumber (no Veneer). This is the original design by John Semrad and myself, copied to death now.
    • TTM Stainless Mat and Oil Damp Weight
    Japan, TTM Stainless mat (6.61 pounds) plus TTM oil filled record weight.
    • TTM record stabilizer TTM three piece set
    Very hard to find, grateful I was able to purchase this last week.  Three piece TTM record stabilizer replaces my previous single piece unit.

    • Soulution Soulution 760 LEEDH
    Soulution top tier DAC, really pleased with performance of this DAC.  

    I still prefer analog but many recordings that were digital to begin with (and vinyl cut from CD master) are better on Soulution than on turntable.
    • Soulution 701 Mono Block Amplifiers
    Soulution top tier 2KW solid state amps from Switzerland

    View of two important pieces to maintain LP collection
    • Milbank Transocket three phase 750 amp

These exchanges give me strength
I understand, and if there is an LP I have an extra of, maybe I could bring you good luck by mailing it to you
the lp collection was the easiest thing to sell, so they had to go. I have no regrets, I would do it daily if need be. I appreciate your offer on sending me duplicates, but I will be fine
Because I my case corresponds nearly to the letter:
I have a (young son and daughter) and should be thinking about retirement and instead work 12 hour days.
And I learn from you guys to be (a little more) positive
The good news? I have my health, my wife and (kids) and my music. We are blessed in different ways and need to remain thankful for all the positive things life brings.
.
THAT is what I must keep my mind tuned to.

Thank you, gentlemen!

I never heard this demo (Bob Carver), but all reports were that it was successful
An interesting side issue raised by an engineer: how Carver's experiment successfully impressed attendant ears -- even (esp) using a lossy reproduction (a very well balanced one, of course).
The ability of our ear to compensate for what is not quite there in the frequency domain, while RECOGNISING sonic differences (i.e. the same amp sounding "like tubes" for example), was uncanny.
It seems obvious that the circuit B Carver used to emulate each type of "sound" was a) unsurprisingly, very good b)difficult to fault due to the system.

Which makes me wonder: a (lossless) 24/96 may be good to have. As Eldartford notes, how lossy is the system -- basically: 1) the data extraction/conversion "kit" AND 2) the transducers (SPEAKERS) through which we listen to the reproduction. {12/36 for example?}

Albert notes
I (...) was not prepared for the improvement in performance. Odd, since I am running the VTL 750

Good for you!
OTOH, no surprise, really, considering the speakers' +9db (spl) in output. The difference in the speakers' headroom (dynamic range) is huge. After all, 750W/channel translate into nearly +29db spl -- BUT, how many transducers can withstand a 750W energy push... Now you can achieve those 29 sound pressure db's with 100W (i.e. 20db+ the extra 9). Many transducers can withstand 100W peaks, and so can many amps -- certainly yours can!
Cheers.

gregm

Choices indeed, Albert! With an extra 9db spl efficiency (if I remember correctly) and all other electrical things being equal (which they rarely are, alas!) you will be getting the same spl with a ~40W triode (1/8th). Not bad!

gregm

Detlof, my system would no longer qualify for advanced comparisons! (But I wouldn't mind being on the "comparisons committee"!)
However, it does play some music and thereby keeps me company -- which is a blessing in & of itself..:). Cheers

gregm

Detlof, at Albert's rate it should only take you ~6 years!
I was once contemplating copying my LPs on digital for conservation purposes... gave up on that VERY fast (about 1hr/LP, forget it).

gregm

Albert, have you ever pondered how long it would take you (and many others here) to listen to each LP in your collection just ONCE again??? Scary isn't it!! Cheers

gregm

Dear Albert, this surpasses anything I had ever dreamed of, or imagined, in aesthetic simplicity, refinement and quality...
You are setting a benchmark!
