What's under your amp?

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.

Aurios Pro MIB lie between my amps and Zoethecus amp stands.

Can anyone here explain what the mechanism is that would excite something inside a ss amp that vibrates because it is not "isolated"?

Is it not besides the point to use a platform when air-borne vibrations will strike the amp nonetheless and, assuming there is a mechanism that somehow affects the sound coming out of it, cause problems?

Why not build a concrete shelter in the backyard and run longer cables?

Pretty sad when you can't see that mega buck power amp looming in your room though.

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.
