The washers I use with my spikes cost me $12 for 8 pcs, I think, and it seems highly unlikely that they perform worse than gold plated ones. But still, it's hopeless to adjust four spikes, so I believe vibrations are in principal unavoidable. But does it constitute a problem?
For some background, I found a paper that uses a smidge of science for an introduction to a bit of the basics of (de)coupling using spikes and (visco)elastic materials 101: www.genesisloudspeakers.com/whitepaper/Genesis_Loudspeaker_Coupling_Decoupling.pdf If I'd buy something from the site mentioned above, I'm afraid I'd get stuff that's been lying around in his garage for 25 years. The material might have hardened in that time span. And I suspect that it's Sorbothane, by the way. Also, I rarely believe what I can't verify by myself, so I'd feel intellectually naked if I used sighted listening tests for evaluation. And it would be truly exhausting to perform any kind of blind listening tests in this case. What to do? The obvious answer is of course to measure the vibrations objectively: au naturel, with felt cushions, when adjusting the spikes, with spikes, with Sorbothane cushions, ... (Almost as exhausting.) There are plenty of apps that measure vibrations, some even in 3D. Perhaps one of them would suffice? For instance: https://play.google.com/store/apps/details?id=com.vibrationmeter https://play.google.com/store/apps/details?id=com.vrmobile&hl=en https://play.google.com/store/apps/details?id=com.lul.vibration.monitoring&hl=en https://play.google.com/store/apps/details?id=kr.sira.vibration&hl=en Has anybody done this already? I'll see if I can find the time to play a little with all of this. But unfortunately it'll take a while. Right now my main stereo that drives the floorstanders isn't even functional, as my media server is, ehm, resting. Thanks for your input, guys!
