What's under your amp?

The ROCK, I have 400kg rock from my garden, find it is fun for the amp and look great. My amp is too heavy one of custom build rack could not support, and I did not have budget to buy an expensive stand...so that "rock" kind of working out for my system.

Amthanh, that rocks! Pun intended. I actually prefer to put my stuff on slabs of maple whenever possible. What is under the cabinet? My situation is such that my listening room sits on a concrete slab.

Try a Sistrum SP-3 or 4. Call Robert at audiopoints.com. I have his SP-101 stands under my VAC 220 Monoblocks and love what they did to the sound; it cleared up the noise and increased the resolution. Robert recommended audio points under my VAC 2.0 PHI preamp so I tried them too and was absolutely amazed how much better every thing sounded. Money back guarantee doesn't hurt either.

I completed assembling the basic combination of support elements that Pierre Sprey of Mapleshade Records recommended just a few years ago. Most of the ideas are still current on the website.
My Cary SLA-70Sig amp has three of the latest generation of Ultimate Triple Point V.3 beneath the amp. On each output transformer is a Small Heavyhat Triplepoint. I use a Virtual Mode D'Bag on the power transformer (the Large Heavyhat Triplepoint is on a Sonographe SG-3 Turntable wood plinth surface). The sound is helped by these weights.
The Ultimate Triplepoints V.3 pierce directly into a Clear Lacquer Mapleshade two inch thick maple block 24" x 28".
Beneath the maple block corners are four IsoBlocks, each consisting of a stacked pair of triple-layered [ribbed rubber/cork/ribbed rubber] vibration absorbers.
To say this combination approach of Pierre Sprey favorably transformed the amp is an understatement.
