WHAT HAS WORKED FOR YOU? ISOLATION PLATFORMS, FOOTERS, ETC. for a DAC?

What is reasonable to expect in SQ gain with respect to a DAC, since there are no actively moving parts?

Footers only? Platforms only? Or is a combination of both best?

Keeping this open ended (as well as budget wise) to see what Audiogon Members recommend and advise.

However, thoughts on Gains v.s. Spend with the specific products you are recommending are welcome and will be very helpful.

The only footers I have used in the past are those from Herbie's Audio Lab.  I have used two different 'audio' racks (which have been dismantled) and I am using their shelves as isolation platforms for my speakers and other components (but not the DACs).

The DACs in use are a Schiit Yggdrasil and an Exogal Comet Plus. The stock rubber footers with the Yggdrasil are as basic as they come; The Comet has an acrylic plate with rounded metal screws.

THANK YOU!

And is why roller bearings are best positioned as an equilateral triangle.

Excellent David! I have a mix of the original Level 1 (same as the new Level 2, but with the cups made of Alcoa 6061 instead of the harder, superior 7075 of the Level 2, and the cup's bowl surface polished to a smoother texture with finer grit) and Level 3. The level 3 is made as per Barry Diament's design idea---a cup underneath the ball bearing, but no cup above it, the ball bearing instead riding across a flat, hard, smooth surface of the users choice. I found some stainless steel discs on ebay---very cheap!

For a little better version of a roller bearing design than the Symposium (fine as it is), check out those of Ingress Engineering in Canada. Machined to Barry Diament’s specs. Cheaper too.

Hey Geoff, as a ceiling is no more free from seismic vibration than is a wooden floor, what about this?: Build a structure that sits on the floor (like the frame of a children's swing set, except with two parallel top rods or beams), from which a shelf is suspended on bungee cords, the turntable sitting on the shelf. I realize the cords should be as "soft" as possible, for the lowest resonant frequency and therefore greatest isolation. I don't think I want to drill holes in my ceiling for eyebolts, hoping to hit a 2 X 6 behind the sheetrock!
