Do equipment stands have an impact on electronics?

You neglected to add your personal tests and measurement results to the documents you supplied a link for. Maybe you felt your results were irrelevant or inconclusive. Tom

I didn’t neglect it. It’s not up to me to test anything for any other purposes than my own. It’s up to a third party to verify and validate claims or whatever and publish data. Didn’t you know that? I feel that your refusal to stop ignoring the evidence that vibration isolation is effective for improving audio system performance is irrelevant.

Geoff posted a link that shows how to measure vibration, but it doesn't show how to measure the affects of vibration on audio as I requested. So yet again Geoff has failed.

Ralph, I've been in this thread for only the last few pages, so you should have seen my qualifier about vibration that I'm specifically not talking about turntables. Yes, obviously vibration when cutting a record, or playing it back later, will affect the sound. I think I also mentioned that tubes can be microphonic, so there too vibration can possibly affect the audio. I'm sure you know that I'm talking about wires and solid state gear, and all the other silly "vibration" products believers waste their money on.

As for LP distortion, just because cutter heads are powered by large amps has nothing to do with the amount of distortion throughout the entire signal chain. Competent digital converters (ie: CD quality at 16/44) have typical distortion less than 0.01 percent at all audible frequencies right up to the point of hard clipping. I'll be glad to see your real world distortion numbers for sine waves on an LP played back at typical levels. Use the best test tone LP you can find, with the finest turntable and cartridge you can get your hands on, and have Michael Fremer align it if you'd like. :->) I imagine that best case it's at least 100 times worse than the distortion of CDs but, as always, I'm willing to change my opinion as soon as you or someone else shows actual evidence. So whatcha got?

every environment is different and vibration sources and amplitudes and frequencies vary all over the place. Thus, any attempt to explapolate the measured performance of an isolation device's effect on the audio signal and say this is what you will experience in your system is naive. On the other hand you naysayers do come across as quite naive sometimes. 

Clearly and practically vibrations are worth some concern when dealing with mechanical transducers like phono carts and speakers. Also with devices like tubes that can clearly be micro phonic. Inherently less so if at all with most ss components. I would even entertain that vibration could negatively affect a cd optical drives ability to function optimally to some extent. Thats pretty much it. Amazing such a long thread full of mostly showboating and not able to constructively focus or agree on anything.
