amp platform suggestions...

Two inch thick maple cutting boards totally bloated the sound of my system. Slow, confused, overly warm, muddy, you name it. Simply put, the maple cutting boards were terrible in my system.

WOW! It's amazing how the results have varied so much. Has anyone used a 1" thick polycarbonate as a platform?

Yes WOW - that's why the constant caveat YMMV

The Polycrystal, Symposium Ultra and Black Diamond Racing have all sounded good for me, as do the Sistrums. The Silent Running gear is supposed to be awesome. But you are in a different budgetary league.

Also FWIW - I have seen people argue that a cutting board does not sound good unless its made of end cuts or one piece. And here I thought that wood was wood...

Yes, I am currently using 1/2" Lexan shelves. Best solution I have found yet. And don't confuse Lexan with Plexiglas. Two different materials.

In time I may try two pieces of Lexan with a piece of acoustic felt in between. Not sure if that will be an improvement, but I want to try it. I have lots of Lexan so it's just a matter of getting around to it.

Fiddler - for a long time people recommended - and as far as I know still use Vibrapods between two pieces of material like Lexan.
