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.

    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.

    • Soulution Soulution 760 LEEDH

@bdp24 the minusK is a passive technology, see here

I have no particular point of view on the relative merits of this approach versus the vibraplane or active systems but I’m convinced any serious turntable setup requires some form of seismic isolation 

folkfreak

Actually the rationale for the Herzan was a little different. My house suffers from a lot of seismic activity (mostly construction and traffic) and no amount of mass will deal with that hence the need for some form of active solution. I also use Townshend stands under my speakers, have you tried similar on your speakers? It changes the presentation (no transmission of bass via the floor) but seems truer to real acoustic bass in a concert hall

folkfreak

My turntable sits on a Herzan platform, itself on a Grandprix wall shelf which in turn is isolated on dedicated wall studs with stud dampers ... vibration is in all places a problem to be avoided. But definitely worth experimenting with the  they will do is address low frequency vibration (as the ball type footers such as the Apex do) but will do relatively little with higher frequencies which is what the footer solutions deal with ... I suspect you need both

folkfreak

I’m with you completely. Crazy how much all these things matter. My current setup is the quite insane
1. Grand Prix apex footers with SiNi balls
2. Grand Prix Monaco stands with stock Perspex shelves
3. Marigo composite N41 spacers
4. Marigo sub shelf
5. Marigo large spacers
6. Marigo F8 footers
7. The amps themselves...

So six independent layers of isolation between the amp and the floor, the effect of each stage being very apparent. Upgrade to Ron’s latest footers imminent as soon as he has them in production.

folkfreak

Albert -- your experience with amp stands mirrors mine, tube monobloc power amps are very sensitive to what's under them. If you did want to keep the Billy Bags you could try a couple of Ron Heydrich's Marigo shelves between the amps and the underlying stand. These composite shelves do an excellent job of taking out the impact of whatever the amp is sitting on (be it perspex, metal or whatever). In my system the impact of adding them between my amps and my Grand Prix amp stands was audible and very beneficial
