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!

Yes, with the upgraded tungsten balls. Great under pre, CD players and transports. I'd actually forgotten about them. Used them many years ago, then sold my transport and preamp so I sold them also. 
I have had good results with the Symposium roller block jr's HDSE under my Modwright Marantz CD player.  Better soundstage and a general focus on the instruments.
I have found that every part of a system should be isolated from the floor, including transformers, speakers---everything--moving parts or not.  Maybe not the heaviest of speakers, but Maggies for sure--too delicate to not be affected by vibrations feeding back from the floor.  
The Vibraplane, although expensive, does an amazing job. It's been around for some 25 years now and if I'm not mistaken was what got this whole audio isolation thing started. The Vibraplane from what I've been told is used to isolate electron microscopes and I've heard they have been used in navy sub to isolate sensitive eauipment.
Another vibration isolation tweak for the financially strapped audiophile - a set of three or four Super Ball and Snaple bottle cap assemblies. The Super Balls are the 1" high bouncing colored balls found in bubble gum machines. But not the larger balls.
