Granite under your amp???

I had an extra slab of 1" granite laying around from my kitchen so I did a little experiment... I placed it on top of my turntable stand with 4 Michell Engineering cones underneath it... and then my Gyro Dec on top... and it was the cheapest improvement in sound quality I have made in a long time...

Tim-When I had my audio crisis a couple of days ago I was considering taking a ride over the falls.David+99

I was able to get a couple of 15x24x1 polished scraps of marble from a local tile and counter shop for my amps. They had a pile of scraps from jobs and let me have them for free. All I had to do was clean them up.

OK, different audiophiles say that a hard surface, like granite under the amp makes it sound better and other audiophiles say that if you isolate it on a air suspension device that it sounds better. So, which is it? And how could both be better with such different approaches?

I think that there can be MAJOR differences with various tweaks such as those that are weight, isolation, coupling, damping, etc... based depending on the type of flooring that one is on. Someone on a hard concrete slab will have VERY different results using the same tweaks as someone with their gear on a suspended floor i.e. over a basement or crawlspace. The results from one suspended floor to another suspended floor will even vary as they may have different levels of support / flexing taking place. Sean
