In the past I sold Hafler amps and they sounded good. But I never liked them enough to own one..they were good enough to use on subs but never full range in a top shelf system. Tom
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?

I’ll email you about my project because I imagine you’ll find it interesting. And maybe you’ll be around for a phone call over the holiday "dead" week between Xmas and New Years? I'm sure we do in fact agree on 90+ percent of this stuff! I'm usually around- quite often that is our busiest week of the year. I am familiar with the nulling technique- hard to get through school without knowing that. I am skeptical that the test will have the resolution required but I suspect that will have a lot to do with what exactly is being tested. A customer of mine liked to replace parts in the power supplies of his equipment. In order to know if he made any progress he placed a microphone in his room at the listening chair and then ran sweeps and distortion tests, and compared them to 'before' and 'after'. He was thus able to document what he heard. |
ethan_winer It’s clear that Geoff Kait doesn’t understand what nulling is or how it works. I’ll give you a clue: it doesn’t "measure" anything. Here’s a more complete explanation, not that you’re interested in learning anything but maybe others are: http://www.youtube.com/watch?v=BYTlN6wjcvQ&t=53m39s Right, only geniuses like yourself can understand nulling. Only a genius would be able to find some hare brained method to prove his phoney foregone conclusion. You'd fit in very well in the witch hunts of yore. |
Can you null the same component ouput when played from a Sistrum Platform and then the same component played from a Springy Thing Platform?. Of course when you playback the difference output you need to choose which platform to launch from. If you were to add the difference to the Springy Thing Platform on the rerun it would gain about 1.5 db in amplitude and lite up the wall behind the speakers versus just the orginal Springy Thing playback .Tom |
