Vibration Control

The main thing here is to audition it and see if you like the result. If you don't, return it. But why dismiss something out of ignorance. I've tried things where I liked what they did, and things that I didn't. I tried some Walker Audio brass/lead discs that seemed to deaden the sound when placed on equipmemt. I got a 5" thick maple board to put under my turntable and it did a remarkable job of opening up and clarifying the midrange. 

It's cool just to try and experiment. Maybe you may not understand why it makes a difference, but it really only matters that it does or it doesn't. 

It always has a positive effect, the key question is how much does it improve the sound you hear and how much does it cost and are you willing to spend. Anyone who denies it either is just plain stubborn of cannot hear properly. Or maybe their equipment is somehow already isolated well enough for it to not make much of a difference (highly doubtful).

It is the easiest thing to test/compare. In my experience, I've had the most improvement with my turntable (by far the biggest change), then my speakers, then my amp and lastly my preamp. Supposedly, it even helps with the a power/line conditioner, but I haven't reached that deepest end of the insanity yet (or fuses, or contact fluid or super expensive cables).

Meant to say least with my phono stage. My amp is integrated.

As with so much in high end audio & often life, there’s so many differing opinions & Often no definitive science as to why.  Added to this, we all hear & perceive things differently & have different tastes. This is sort of similar to solid state amps generally measuring better than tubed ones but often don’t sound as good. Thanks everyone for all your responses. Fun stuff!

Analogj why would you say ignorance. I would suggest that if you tried things on your system that you don’t know why that’s Ignorance.

there is a engineering rational for the reasons which were mentioned. So what’s the  premise that your cD transport would benefit from vibration isolation.
