Do equipment stands have an impact on electronics?

Thanks Atmasphere for providing that very useful information.

It certainly "rings" true for me.

Gotta expect that the experts who make these things and do it well are aware of the issues and address them to some extent accordingly which is surely part of why the good sounding gear sounds good.

As a simple home user, I leave those things to the experts and judge with my ears. At home, I do what I can to minimize vibrations that I can control, like the effects those coming out of my speakers may have. Or those transmitted through the floor or can occur whenever gear does not set on a solid and firm foundation.

My goal is to enjoy great sounding music. Some things are best left to the experts to solve, those who actually provide the gear we use and listen to with pleasure.

Yes, but even top end equipment is built to a price point and after market solutions to these problems can be beneficial -- case in point changing the rubber ring tube dampers on ARC kit to Herbie's dampers (see this thread) -- this is a $500 change on a typical ARC top end tube amp (at retail) and likely many times more than the cost of the rubber rings

Secondly the manufacturer (with some rare exceptions) does not know the circumstances of where/how the equipment may be racked hence the validity of numerous footers and supports such as being discussed in this thread

So many reasons to believe that even a well designed and vibration thought out device can be further optimized

I have and I strongly suggest to mechanically direct couple all internal major parts of an audio component. Nothing is decoupled in my power amps. These parts include transformers and any all  filter caps that are chassis mounted. I have direct coupled the 4lb copper heat sink that stands vertically and has attached the 2 power mosfets which is then bolted to the bottom plate of the chassis. The main circuit assembly is mounted to our Sound Works platform and tensioned thru the board and out thru the chassis frame below and secured.. All of these parts reside on Audio Points and our coupling discs and must be secured and clamped into place for maximum audio performance and safety concerns. I had cut and drilled brass cylinders that mount near the non existent  corners to which the top and bottom plates are tensioned. The whole component is then mounted externally to one of our Sistrum or Rhythm Platforms with our points which face north to the 3 tensioned internal connecting rods.. This was certainly an exercise of will but the payoff is high... and wall to wall tall, with resolution that extends past my listening chair. The endeavor was to make all the internal vibration go in one primary direction..to ground. To do this, like geometry and materials are required to maintain speed and operational efficiency. Tom

I realize I’ve probably asked you this question before but now that you’ve taken case of the vibrations produced by motors, transformers, etc. In the component and vibrations that might wind up there due to acoustic forces how did you address the seismic vibrations? It appears you’re ignoring them. Maybe you are thinking the seismic vibrations go up and are are taken back down by the Audio Points, or perhaps you believe the Audio Points disallow seismic vibrations from being transmitted up to the component, who knows? Am I missing something? I hate to judge before all the facts are in but you guys appear to be behaving like the proverbial ostrich with his head in the sand. It may very well have been an "exercise of will" but apparently you willed the whole seismic isolation argument away with a wave of your hand. Speaking of which whatever happened to your seismic waves?

The response is coming soon and what you have exercised for 20 years or more has nothing to do with how LIGO operates as it does not relate to your audio products.. In your instance, it is not a single case of suspended animation..Tom
