Isolation feet/cones for PS Audio NuWave DSD DAC

Thanks for the additional input.
My system is on a custom rack made of Baltic birch plywood. Each shelf is about 30 mm thick and the feet have 4 stainless steel spikes on the bottom.
Seems like a similar situation

As far as cones go, their effectiveness is directly proportional to their hardness on the Mohs hardness scale. Thus you’ll find super hard DH Cones are at the top of the food chain and softer materials like carbon fiber, brass, steel and aluminum are farther down the food chain. DH Cone ceramics being 9.5 on the Mohs scale (where diamond is 10.0). Brass and most other typical cone metals are down around 3-4. For non-cone type footers it's a whole different ballgame as their method of operation varies.

@itsikhefex; I had Herbie's Tenderfeet under my Dac and Transport, I switch to the Large DH Cones and heard a great improvement. If you should decide to go with the Herbie's Tenderfeet, I might know where you can find a few pair at a reasonable price.

Not trying to be contentious but isn’t the question of DH Cones vs Herbie’s Tenderfeet also a question about the relative merits of vibration draining vs vibration damping/isolation?

I’ve read at least one "expert" recommendation to use both: a hard cone (brass in this particular article) under a component (point facing down) to drain vibration into a wood plinth and a softer elastomeric footer between the wood plinth and the equipment rack shelf to provide vibration damping/isolation.

I’m not arguing for or against anything here, just wanted to provide a slightly different context for considering the OP’s question.

>>>>A valid point. However, it is actually the case that when DH Cones are used in BOTH locations, under the component AND under the plinth, the sound is even better. This is not to say damping doesn't have it's place as capacitors, CD transports, transformers, chassis, etc. should be damped.
