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.

Hi Bomer,

what did you have prior under your table before getting the Minus K?

I also have a Minus K (custom made one) undernieth my TW Acustic Raven AC3 none suspended table.

Under my mono blocks I actually have Sistrum platforms, there is allot of info. in relation to these and what they offer both for tube and solid state, I like them and haven't looked for others.

What size is your Minus K?

Mine is BM-8 and it 28.5" x 21" x 4.5" larger than any of the standard units, also has a much greater payload weight range, 110lbs-175lbs.

My AC3 fits nicely on it.

Here's something that might interest you;

With a turn table on top of a SR Ohio base placed on a audio stand, while the needle is on the record; taping the actual stands pillars and other parts or the actual platform could hear the noise clearly threw the speakers.

Using a Symposium Ultra platform did th same thing and could still hear it clearly but more of a thud sound.

Using the Minus K, absolutely nothing ZERO!

That was very interesting indeed.

Hi Atmasphere, I would also think that this would greatly benifit any tube gear placed on top also, I was pleasantly surprised with my findings.

Your thoughts in relation to this.
