Here’s the thing: When someone makes a claim, the burden of proof is on them. It’s not up to me to prove that a 2 volt drop doesn’t have an audible effect. It’s up to the claimant to prove that it does. This is Logic 101. More important, trying to assess the affect of a power wire by measuring the AC power voltage is beside the point. The *only* thing that matters is what happens at the output of the connected equipment. Competent audio gear is immune to small changes in voltage, and routinely filters out the typically small amount of noise riding on top of the power voltage.Welcome Ethan! Thanks for chiming in. Yes, there is a burden of proof to some degree and thus the animus for this thread.....
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 just realized the topic of this thread is vibration isolation. I love this topic! Why? Because it's so easy to prove or disprove by measuring. But who has ever done that? Well, I did not long ago. Enjoy:Yes, yes. I have been trying to coax out that sort of information, but everyone is resisting arrest.... |
This is what Tom wrote initially, theaudiotweak The amount of reflected signal refracted back into the signal path is what's most important. The signal path is all solid materials including their boundaries with other solid materials. You cannot measure refraction with a laser as described. You say refracted and reflected. And more importantly what on Earth are you even talking about? How does your post address what atmasphere wrote regarding lasers and speaker stands? |
Why does it matter if a laser shows that the surface of a loudspeaker enclosure moves? How much movement is needed to make an audible difference? I'll never understand why some people are so willing to measure the wrong things and come to a wrong conclusion, when it's so easy to measure the right things and get the right conclusion! |
