Vibration

I used to do it with my Wadia CD player. I imagine you are trying to get your components in between your speakers but you want them low so they don't interfere with imaging. If long as you use a good amp stand you should be OK. It really should be no different than putting the component on the lowest shelf on a rack.

Hi what are you trying to accomplish here? Lot's of great racks, amp stands, various footers...all of these things make a impact...some better some worse...

Check through the system pages here on Audiogon, you'll find plenty of systems configured with equipment on individual platforms. You can ask specific questions on those pages. You'll probably get some good, detailed answers from members who are doing it.

Yes

Having separate mechanical ground planes for each piece of equipment makes for a noticeable improvement. Also there is increased lateral rigidity because of the floor proximity to the piece of gear as well as a shorter path for vibration to migrate to ground. All these factors makes the sound stage more clear, mid bass punchier, overall texture of sound is more dense and complex. Tom

What vibration or mechanical energy are you trying to isolate with a amp stand? Are they just for tube amps to reduce harmonics?
They do look cool sometimes.
