Isolation feet/cones for PS Audio NuWave DSD DAC

FWIW - the DIY bearing blocks are installed.  I have them under the pre-amp.  The set up looks a little "odd" due to height (Herbies Tenderfeet>> 1.5" plinth>>1.5" diam. SS ball>>Freya).  The movement the Freya displays when tapped from the side is striking.  It looks exactly as though it is suspended between springs allowing 360 degree movement in a horizontal plane.  

Gear had been powered down the last day or so, so playing some warm up tracks before listening "critically".  Might have to experiment next with suitable spring(s) to replace the Tenderfeet.   

My dac is the PS Audio DirectStream Junior and I'm getting fantastic results with footers from anvilturntables.com.

Looks like a hockey puck with small magnetic balls underneath. You can fine tune the tension by adding or removing balls

I have had tremendous success with Feet of Silence by Solid Tech. I think the greatest advantage to the FOS is that you can use them on virtually any surface and get consistent results. I found this review on Audiogon. I have used FOS in my system for years- I would be hard pressed to ever change.

Changing the subject a bit, but would Large DH Cones work under a turntable?
The TT sits on a bamboo platform with Herbies footers underneath. Looking for footers that would drain vibration from the TT to the platform. Need a budget solution.

I don't see why not.
