What would you upgrade next if you had my hifi ?

Hello Palasr . The paneling that a few members have mentioned is actually hard wood flooring 3/4 inch thick , laminated not nailed to two layers of 1/2 inch drywall , gives us about one and three quarter inch thick wall . The wood has a very positive effect on the sound over drywall ( sheet rock ) . The audio part of the system runs off two dedicated 20 amp circuits with isolated grounds , terminated with PS Audio Soloist outlets . Audio shelves are two inch thick , plus each component has it's own isolation platform .

Wow, that's a lot of wood. If your system isn't adversely affected by it (bright?), then leave it.
Someone above mentioned buying a table, I totally agree.

Not sure what you are doing about power, but in my experience getting a PS audio regenerator (first powerplant premier than upgraded to P5) was a huge boost.

Second, I used to have Studios as well. Then I did an in room shootout with Verity Audio Parsifals and decided to keep the Parsifals. I then did the same between Parsifals and Eidolon visions and prefered the Eidolon's. I now feel I am a few steps up with the Eidolons from where I was with my Studios. Lot more $$$ though. For current used price the Studios are hard to beat.

Elevick , there is allot of wood but it had a very positive affect on the sound , I don't think I could go back to drywall , no brightness at all , but I have many room treatments as well .
Edorr , I did compare the Studio's to my Salons but the Salons had a fuller more detailed sound . I had them upgraded a few years ago , it brought there sound into the 21st century .

And it brought the looks into the 22nd century. I always loved the aestetics of the original Revels.
