Clearly and practically vibrations are worth some concern when dealing with mechanical transducers like phono carts and speakers. Also with devices like tubes that can clearly be micro phonic. Inherently less so if at all with most ss components. I would even entertain that vibration could negatively affect a cd optical drives ability to function optimally to some extent. Thats pretty much it. Amazing such a long thread full of mostly showboating and not able to constructively focus or agree on anything.
Speaking as someone with as much experience with vibration as anyone and a lot more than most, and having supported (no pun intended) some of the most important and famous rooms at CES, there is actually is not much that won’t benefit from vibration isolation. To name a few things: solid state amps, printed circuit boards, power line conditioners, DACs, CD players, subwoofers, big heavy turntables the ones with 50 lb platters, power line purifiers such as Quantum Corp. stuff, speaker crossover networks, cables and power cords and of course tube electronics and speakers. Oh, almost forgot, tube and solid state power supplies.
No offense Mapman, but you’re out ranked. 😄
And you don't have to be rich as Croesus anymore. If you’re a clever monkey you can isolate everything in the whole damn room for a hundred or two hundred bucks. I’m not hot doggin ya.
