Silent Running Audio vs Minus-K under tube amps

Has anyone had experience comparing the results of isolating tube amps with Silent Running Audio platforms versus using an isolation platform such as a Minus-K (or similar). I recently placed a Minus-K BM-8 platform under an non-suspended high mass turntable and was amazed at the improvement in the sound. I am trying to decide if the Minus-K would work as well for tube amps or would the Silent Running Audio Ohio Class platforms be a better choice. I have the amps on Grand Prix Monaco stands with the Formula carbon/kevlar shelves but I can feel significant vibration getting to the amps from the sub-woofers in my speakers (Vandersteen 5A's). The amps are sitting within a foot of the speakers due to short speaker cables. Thanks.

I can't speak for Grand Prix Audio, but my understanding is that carbon fiber under audio components does not isolate per se, but rather, changes the frequency at which an items resonates. This is why carbon fiber works spectacularly well with some gear and can make things worse for others. I have Black Diamond Racing carbon-fiber shelves under my turntable and CD player, and they improve the performance of each.

Coincidentally, I have Silent Running Audio Ohio-Class bases under both my darTZeel transistor amp and VAC Renaissance tube amp -- Ohio-Class bases are custom-made based upon the particulars of each amp. They did not replace any other bases, so I am not able to make comparisons.

I'm not a scientist and can't respond to your question. All I can add is that one or more of the principals of Silent Running Audio allegedly (I emphasize "allegedly") used to supply isolation technology for navigational instrumentation employed in the U.S. nuclear submarine program and in this regard, were either employed by or consulted for Electric Boat. This could be typical two-channel hi-fi bullshit, but it's worth mentioning that Lamm recommends Ohio-Class bases under it's $130K monoblocks (and other elite manufacturers like Tenor recommend them). I should add that the name "Ohio-class" refers to the largest known SLBM-carrying nuclear submarines in the U.S. fleet.
