I can easily see the benefits of isolating components, particularly those with moving parts, if you live in a house with suspended floor, or heavy traffic, or central air conditioning, or the drier spinning next door, or whatever that shakes the house...

My house has concrete floors and walls, no traffic arround the neighbourwood, no central air, nothing really rocks but the music, and the kids upstairs, sometimes...

I very much doubt that I need more than a solid rack, still, if someone wants to bring such device, as long as its footprint is not wider than 17", and it is not taller than 1", I am willing to test it... :MILD:
