Granit amp stands are they killing my sound?

Syntax, could you please describe the effect of placing a Vibraplane under your Lamm amps? I have one under my turntable, and I agree with you. It is so effective that I closed that chapter.

I have heavy SS amps sitting directly on my floor. I'd like to try two Vibraplanes under them, but it will be an expensive experiment. Any advice or comments you may have would be appreciated.

Thanks Syntax. Those results seem impressive. Are your amps the Lamms with tubes, SS or hybrid? Do you think the most improvement with the VP would be with tube amps or would SS also benefit so dramatically?

I'm thinking of getting two of the active units with a compressor in the basement.

Sorry to sidetrack this discussion about granite amp stands.

Thanks Palasr. I'd like the compressor out of site. I know they can be quiet as I've heard a Jen-Air? at Sounds of Silence, the Vibraplane distributor. I just don't want one in my formal living room. I wish I had a dedicated audio room.

I also have my passive Vibraplane preloaded with one 1 1/8" plate of steel weighing 136 lbs which brings my total load to 250 lbs. I agree, the improvement is very noticeable.

Air is great for isolating a component like a turntable and I'm sure it can be effective with amps. But when it comes to draining vibrational energy away from a component, there may be better solutions. Perhaps the OP is more interested in draining energy with spikes into a massive platform then he is in isolating his amps from floor born vibrations.

Have you tried putting your Galibier up on spikes or cones on top of the aluminum sheets? That may address both objectives.

My turntable rests on four small ball bearings at the center of each adjustable footer. These drain the energy away from the turntable/motor while it is being isolated with the Vibraplane. I have the option of using four rubber inserts instead, but have not tried them yet. I've been told the ball bearings sound better.

I get your point Syntax. Very funny post! Explain what is between your amps
and your Vibraplanes. Also between your MS and Basis turntables and their
Vibraplanes. Do you think a hard ball or point sounds different from some
rubber footer/insert under the components? If they sound different, surely
science is involved.
