Devil,

Of course music is vibration, but if you only get the airborne kind, nothing going through the floors, walls or wobly racks, (mine has about 300 pounds on it), there should not be enough energy to affect the components much, after all, they are supposed to withstand some, particularlly the more expensive ones...

Paul,

I can only speak for my instalation, the rack, with TV and all, is over 3' from each front speaker, and over 1' back, so I don't think it interferes much...

As for other interferences, I can always switch off the TV, etc, if I want PURE stereo...
