...dont't think that this interference is 'enough' to 'destroy' the sound. Or is it that someone has so much better ears, and have listened much more criticaly to sound all their lifes, and they have a much more indepth knowledge of electronics/sound than me (and others) have?

Right, there's a word for those people: "Audiophiles".

Practically any interference at all in the audio signal is enough to 'destroy' the sound for an audiophile. My contention was that mechanically isolating a CD player's casing didn't do anything to prevent interference because there isn't any interference to prevent in that particular instance.
