Vibration control on power versus signal

I am upgrading a power conditioner and was wondering if anyone has compared the effect of vibrations on the actual signal  - speakers and the their cables, amps, phono stages, turntables, other sources with the boxes and interconnects on SQ versus those on the power delivery side- power cords, conditioners, power supplies, etc.

So far, I have seen the benefits of vibration control on the signal via treatment on my speakers, phono stage, amp, and of course turntable. I have only minimally addressed it with my existing power conditioner with Herbie's tenderfeet, which may do something, but don't give the box the floating effect you get with Townshend pods/platforms or Symposium roller blocks.

Logically, I would think the effects of vibration would be much less detrimental on power versus signal, but logic doesn't always work in this hobby. For example, I was told that the BIGGEST improvement heard by Symposium is on CD players, not turntables or speakers or boxed components. That surprised me because of the huge improvement I heard on my turntable with Townshend's Seismic Platform.

It's the only box I have that doesn't float around when I touch it (with the corresponding wires in the back) when I put records on top of it when putting them back. I don't like seeing that movement, even though it is very short lived. I would prefer not to treat the new one, but of course want to have the best sound that I can hear, not just the best in theory.

Thanks for relaying your experience.
