Underneath I have Stillpoints with risers sitting on top of a 2 inch thick maple amp stand. On top a VPI brick for right now, I've used HRS dampening plates ion the past.
What's under your amp?
Interested in hearing the importance (or not) of isolation platforms for amps. Check my system, you'll see I've got my Cary's sitting on top of my cabinet, which is a custom piece made of solid cherry. Very solid, but I'm wondering if maybe the cabinet is introducing vibrations up into the amps, and maybe I could use some help from a platform?
