Granite under your amp???


I have had speakers with the option for granite bases, has anyone used a slab of granite under their amp, even while on a good stereo rack? If so, any changes?

I bought a marble cutting board (or bread board)at a cooking retail store for $20.00. I put it under the cd player I was using, and it sounded much better.
here's what i did for my paradigm studio 60's. went to home depot and bought two 18x18x2 concrete squares and they had some rubber mats(4 to a package) that fit together for kids to play on and two 18x18 ceramic tile sheets. i cut four 18x18 squares from the mats used contact cement and glued one on each surface of the concrete blocks then i glued the ceramic tile on each rubber surface paint the sides of the concrete square and you have a great stand.
cost?? concrete $4 each, rubber squares $15 package of four, ceramic tile $4 each, contact cement $4 can, spray paint $4 can total = $40 talk about heavy and they look great, bass is tighter and there is a lot more air around the instruments.
according to Mapleshade records they have tested all possible platforms over the years and found maple (go figure) buthcher blocks to be the best, even over 100+lb slabs of marble and lead, I haven't done the experimenting to confirm this
Hi Brianmgrar,Under Tech Talk there is a lot of good information on threads-Isolation vs. Absorbtion and Shelf Marerial.

Under Misc. Audio look for the thread-Amps Stands-Do They Work.

There was one called Footers/Shelf Material. Try doing a search.
thick 24inch x 24inch on a side with beveled edges. cost abt 500 bucks for 2 (edges were expensive) they weighg abt 50 lbs+ each. But my ml requests now have a nice base that keeps the spikes from going through the floor.
