agear, Mr. Diament would be the best person to ask. He's pretty responsive to inquiries, and a nice, non-confrontational guy ta boot.
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?

agear What kind of spurious signals and how was it measured? Anyone? geoffkait:Mommy, why is the sky blue? 😳 to which agear replied, I would not expect a technical answer from you at this point. but you're not technical remember? you weren't even able to follow the technical data that's already been presented, including the isolation effectiveness data that a fifth grader would be able to follow. |
but you're not technical remember? you weren't even able to follow the technical data that's already been presented, including the isolation effectiveness data that a fifth grader would be able to follow.you have presented none. lol. Just circular ad hominem babbling and poorly crafted, quasi-mystical science fiction. Next.... |
If I were ever to create an audio company, one name I would most certainly consider would be Placebo Audio, where "the only limitation is YOU!" Ethan Winer has made a lot of people mad over the years, and has been banned from multiple forums for doing so. That being said, he does make some cogent points from time to time: http://ethanwiner.com/forums.htm |
What kind of spurious signals and how was it measured? Anyone?That should not be hard to do. Place a preamp on the stand to be tested. Run the volume up with a shorted input (phono would be best). Subject the preamp in the stand to a 20Hz tone measured at 90 db at the front panel of the preamp. Observe for the change, if any from the output. Ethan Winer has made a lot of people mad over the years, and has been banned from multiple forums for doing so.Part of that is because the guy tends to be a bit of a troll. For example, once he made the claim (and likely still does) that power cords can't make a difference- 'it's a power cord!" was about all you could get out of him. I challenged him to show his measurements, since he's a measurement guy. The funny thing was he didn't have any, and I did. They were pretty easy to obtain, too. When I pointed out that we could see a more than 2 volt drop across the power cord his instant response was that the power cord was a piece of crap. Now that struck me as trying to have it both ways; apparently even by his testimony power cords can make a difference even when they don't. Then it turned out that his reference amplifier was a Pioneer (keeping in mind he is anti-tube) integrated that cost $600.00 (and as you might expect it did not have an IEC connection to allow for easy power cord exchange...). I and others tried to explain to him that the larger heatsinks, better quality components, larger capacity power transformers and filter caps in the power supplies of high end amps actually made a difference but he wasn't buying it (literally). After all that he finally did get banned from that site. I don't find him all that credible and often a bit obnoxious, but that's me. |
