Do equipment stands have an impact on electronics?


Mechanical grounding or isolation from vibration has been a hot topic as of late.  Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room").  The question is does it have merit when it comes to electronics and if so why?  Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

One assumes you meant to say psychological information, not physiological information, about how we perceive sound. If not, how so?


Mr Winer -- if you had taken the time to read the full thread you would have seen discussion of test data showing the effects of vibration on jitter in CD playback. While we can have a discussion as to whether this is audible it seems there is no discussion as to whether the effect of vibration is real

I had neglected to read that piece Folk.  Thanks for that.  I have a few thoughts.  First, the correlation between jitter and digital fidelity or musicality is murky.  From personal experience, I have owned DACs with high and low jitter and musical enjoyment does not always track with specs.  I know people argue all day about what thresholds of jitter are audible, etc and how to effectively measure it and correlate those measurements is no small matter.  Second, the findings referenced by Meitner and the author are interesting, but when crystal oscillators were embalmed in ceramic, "you could hit them with a sledge hammer and it doesn't cause any jitter."  Similarly, the author clearly demonstrated that well designed electronics were essentially impervious to vibration from the loudspeaker.  Finally, a CDP is a poor test subject for the realm of digital and vibration as it incorporates a mechanical element.  Most of us (including myself) are now streaming digital media.  It would be interesting to repeat such testing within that paradigm.

ps as a complete aside I was amused by the following in the WSJ today - if science is struggling to tell us how to brew a cup of coffee is it any surprise we have difficulty measuring the reproduction of music

As a coffee nut, I celebrate that particular struggle.  Counter Culture is based out of NC....
ethan_winer's profane and insulting post was thankfully deleted. It shows there's nothing to be gained by engaging with this guy.
What on earth did you say Ethan?  I missed it.  LOL.  Like incendiary, FAKE news, all contrarian behavior must be banished from public consciousness.  Shame, shame.    

All the giggling schoolboys apparently like each other's puerile and remarkably unfunny jokes. What we have here is not exactly the faculty of Harvard. Did someone forget to put out the Roach Motels again?
