If you don't care to experiment then what is there?

I don't care to experiment further with Sistrum products.

I use a 4" Maple block with Audio Points underneath.

Grant,

My question was one of inquiry as to the reason why no perceived difference was heard or felt when either assembly was placed under your amps. Thats all. Tom

Grant,

I see.

It's a question I cannot answer.

I currently use a combination of a 2" maple platform and Black Diamond Racing Jumbo Pits under my Pass amp. Like Tvad, I didn't notice a difference. This was quite different from my experience putting isolation devices under my dac/preamp, which resulted in improved clarity and focus.

For peace of mind, I left the isolation under the amp anyway.
