Best Footers for DAC?

In January, I plan to acquire my first standalone DAC and am wondering what to try for footers. I currently have original Stillpoints cones under the CDP which will act as transport and a Symposium shelf under my integrated. 
These work well.

In the past, I've tried and been disappointed by Stillpoints Ultra SS and Ultra Minis, brass footers, Cardas myrtle blocks and Vibropods. Are there any products that work particularly well under DACs ? ? ? ? 

I have yet to decide whether DAC will sit atop transport or on its own shelf, so I'd appreciate suggestions for both scenarios, please.

I don't understand!
Aren't DACs fully solid state components with no moving parts? Why bother with isolation?  Are there any scientific reason behind the need for this?
curious...

"scientific (mechanistic) reasons behind use of these for a DAC could include tribo-electric effects, or piezo-electric effects on any internal crystals in the DAC"

Aren't the crystals in DACs operate in MHZ/GHZ range? Isolation from mechanical vibrations would mean nothing to them.  I think the humidity/temperature/athmospheric pressure in your listening room would make more difference in the perceived sound than mechanical isolation of DAC.
Just IMHO.
