Amp Stands - Wood or Stone

@testrun The only reason you need amp stands is to get the amps up off the carpet so that they ventilate correctly. I made a set just recently and used 8/4 walnut on spikes. You have to finish the wood which is more expensive than the wood. Stone is more difficult to mount spikes on, but does not need a finish. 

As far as sound quality goes it makes absolutely no difference. If it looks better to you it will sound better. So, by all means, pick what looks good to you. 

@mijostyn I'm surprised the "moderators" and people on here who swear by the materials used for amp stands are tolerating your opposing opinion.

I agree with you. I posted on this thread that I bet a person would fail a blind a/b test and was essentially attacked for having such an opinion. 

They scolded me, called me a "hustler", and removed my comments. Why?

For being a newbie and disagreeing with their claims. 

I have never heard any amp sound different no matter what it was sitting on. 

Some people may have a more acute ability to hear than others.  I don't, but I do not discount those that say that they do.  

My Audions sit on marble which sits on cherry wood shelves. Two sticks of wenge wood span the Audions front and back leaving a couple of inches between them. On this "bridge" sits a 15lb lead block.

Maybe it's just my ridiculously sensitive hearing and hyperactive neurons, or maybe it's all the tubes in my phono amps, preamp and power amps, but I can hear differences in the sound of different supports beneath the amplifiers. Quasi-authoritative proclamations that this is impossible indicate that your situation may differ entirely.
