Thanks again for your perspective - geez, I should have posted my plan first... it took me an hour to get this rig set up!

I actually have some 7075 aluminum discs that I can attach to the bottom of the amps. I'll give that a try. I would like to loose the Maple shelves as they take up too much vertical space.

BTW, I take exception to your statement that my nuts are not optimized. 8^)

Rollers couple VERTICALLY and isolate HORIZONTALLY.

  Your second point is arguable, but it's not worth having the argument.
  
  Key is that he's not understanding what the rollers do mostly and he can do better by rearranging his stack.

    "Key is that he's not understanding what the rollers do mostly and he can do better by rearranging his stack. "
    
    Again, I appreciate your feedback... but I don't think there is a right answer here, and I don't think I fall into the camp that "doesn't understand". A pure horizontal vibration mode will be isolated by the rollers. Better put, a pure horizontal vibration mode borne within the amps will not transfer into the stack of the constrained layer shelf through rollers as well as it will through rigid couplers. I agree that the rollers will couple the same as rigid couplers for pure veritical vibration modes.
    
    Without experimentation, I think you are taking a leap to say I can do better by rearranging. I will be glad to try your suggestions, but what sounds best is anybody's guess.
    - And I agree you need to experiment. - bartc 05:59:42 04/20/10 (0)
      I have no idea what your stack sounds like nor your sonic preferences. I'm just commenting on the usual physics of these devices and my own experimentation on my own devices relative to my own preferences.
Your nuts and optimization LOL - bartc 07:56:40 04/19/10 (0)
Yeah, that was quite a slip there! ROTFLMAO

The discs should work fine for the purpose I suggested.
