Thick 2" maple amp platform--couple or isolate?

Carpet.

Jeffrey,
In my system, I have two sets of monoblocks sitting on maple blocks from Timbernation. I had considered cones/spikes, but opted instead to have Chris (Timbernation) build a laminated box that I partially fill with sand. The maple block then sits in the 'sandbox'.
Hope that helps,
Howard

The only other thing I tried was the Sound Anchors amp stands, which are beautifully made. I happen to like the looks and the sound better with the maple. Seems a little livelier, and the bass has more body, less thud. So I'm using the amp stands to support a maple block under my CDP. Just my experience, obviously.

That was you who left that litter in my sandbox? Bad kitty!

This is what Chris made for me. I have one for each monoblock...four in all.

Is it the best thing out there? No idea. They work well for me, were reasonably priced IMO, come in any size I want, and the amps won't move even when my 170lb. English Mastiff decides to show off like a rodeo bull in front of the system.

I guess I should mention that I have no affiliation with Timbernation. Just a satisfied customer who likes playing in sandboxes.

That's a great question, Krell_man. I opted for unfinished but only because I preferred that look. I know that Chris at Timbernation finishes many of his amp stands. Ask him, but I think his finshed stain leaves only the thinnest of layers on the surface, so the amp feet would not slide.
