What a totally useless thread full of ad hominem attacks. If the OP actually cares anymore I will add that I concur with Mapman. Apart from turntables, tubes, and speakers, for the most part any mechanical vibration isolation is totally unnecessary with most SS electronics. This can be proven quite simply by gently tapping the chassis and noting that no sound comes out the speaker even with the volume turned up fully. (Of course, don’t try this with a tube amp or with a turntable or with a sledgehammer)
I would add that a large transformer on a massive power amp can vibrate or hum audibly and so can an optical drive when close to the component but this sound is not coming out from the speakers if the equipment is working properly.
