Amp Stands - Wood or Stone
I'm in the process of relocating my audio equipment to a side wall and need to place my amps, AGD Audions, on something. Floor is carpeted. Stands will be very small and won't be supporting much weight. I have access to granite, marble, etc. (next to nothing scape from remodel jobs). Also, have pretty good relationship with a serious wood worker who is happy to cut maple, oak, cherry, most any hardwood, etc. Cost is not really an issue just looking for an opinion / logic around which material I should use. At this point, I'm thinking 1 1/2 to 2 inch thick walnut on some kind of cone / spike legs. Sorry for maybe a dumb question!
Every man takes the limits of his own field of vision for the limits of the world.

+1 bdp24 - I used granite from my local kitchen counter place + leftover 3/4" oak + a sandwich of acoustic wall damp in between the two. For me, it tightened up the bass + it does work when I rap on it with my knuckles - ie no noise thru speakers. I am supporting tube amp and pre-amp and turntable with this. The weak spot is the TT plinth which does resonate when I rap the plinth with my knuckles. YMMV of course. |
+1 @bdp24 - I use a sandwich of granite from my local kitchen counter shop + leftover 3/4" oak + the acoustic wall damp material. I think technically you are supposed to use 2 different materials separated by the acoustic damping material - there is a technical name for it which I forget right now. Am supporting tube amp, preamp and TT with 1 stand under each for a total of 3 stands. Easy to make. No noise when I rap with my knuckles. The TT plinth does resonate when I rap with my knuckles, but unsure what to do about that. TT is a stock VPI prime - 10 years old this Dec. YMMV of course |
@noromance Yet there are limits, whether one likes it or not. Challenge those limits at your own risk. As far as humans are concerned we are way more alike than different. We have yet to see a human with three ears and hearing much beyond 20 kHz is impossible for use, but not for some other critters. Humans can not see with their ears, but bats and whales can. @dmk_calgary What you are trying to do is make a constrained layer construction to minimize resonance. It might work great for a turntable plinth put it will do bupkis for anything else. Many of you have subwoofers with amplifiers installed within. Sealed subwoofers have extreme increases in internal pressure with loud bass below 100 Hz, yet the amps seem to do just fine. An amp out in the room is subject to a lot less. |
Whatever you make your stands from, put your components on Symposium Ultra platforms. The disc couplers transmit any vibration from your equipment or the room and converts it to a tiny amount of heat. I have these things under my components and the difference was remarkable - especially with my tube amp and preamp. Cleaned everything up. If cost isn't an issue, get the Symposium Osirus rack.
