Granite instead of an amp stand?

Why not? In my experience, even concrete slabs are effective. This concept also works well as a stable platform for speakers.

The object of a good amp stand is to channel resonant energy away from the amp, but I bet marble would look pretty cool. Give a listen to Stephen Micus/The Music of Stones (ECM 1384). It's oscillating, atmospheric and hypnotic, made on resonating steles cut into metre cubes of black granite and green serpentine.

Well, all I can say is that once I put my Krell fpb 200c on a Zoethecus amp stand, I was stunned with the increase in focus, imaging, etc. I really was amazed!

That's my point. I heard the zoethecus amp stands and they were great, but the cheapest one I found was 500 bucks. Which isn't too bad except I'm poorer than an audiophile should be. I can get a 3 inch thick 20x20 slab of marble for around 100 dollars, hence my question. But I'm in total agreement with you, if I could nab a Zoethecus I would.

tbadder, stick 3 cones under the marble slab, & yule be good to go... doug. ps - i like putting lead bricks on top of the amps, too...
