Isolation platform for the power amps

i have my amps sitting on brass cones then 2" maple, isoblocks between that and another platform then cones to the floor. complete isolation and it sounds that way too.

Here is the cheapest amp stand you can buy. They look okay, as they are just plain old black amp stands. (They have very little isolation, except for their floor spikes and small rubber cushion buttons, that the shelf sits upon.)

I bought mine used from a friend for $75 for the pair.
He went on to buy some really nice looking Zoethecus cherry wood trimmed stands (used) for about $700 a pair, and then upgraded again to some great stands (Grand Prix Audio, I think) for about $3,500 a pair. His system sounds great, and he thinks the stands have helped a great deal, especially the Grand Prix Audio stands. (To be honest, I really have not heard the difference myself, but then again, I don't live with his system everyday, so I can't say for sure if they work or not.)

I use these same stands for my amps, and while I probably could (and maybe should) buy something better, it is just difficult for me to spend hundreds, if not thousands, of dollars on stands that sit 3 inches off the floor, and which amps, (with no moving parts), sit upon. (I'd rather put the money into better equipment or music myself.) My wife thinks they look just fine too.

Try placing Herbiesaudiolab.com "Tenderfoot," or "Iso-Cup" footers between amp, and one of the bases mentioned by Bdgregory, above.
Herbie's has a ninety day (!) home trial policy, so you can't go wrong.
The current version of Herbie's footers isolates/absorbs all those bad vibrations received from the environment, and from the component, itself.

Now Now, If you had done asearch you would have seen my post on isolation. All these sound smearing distortion making,make blacks turn less black and just put a veil over youyr speakers. Hears the trick you build a box like strucure with rebar put woodaround the ouside and inside but use 3 long corks to span the rebar at the bottom rear. The youyget some cement premixed is easier but you can add colored dye, I'm sure McMaster Carr has some.Pick a subdued color. The pour the colored cement into the mold.Now just wait till it dries.While youve got the mixture all set up build a box for the cover at least 2-3 inchesthick the boxshould be 5-6 inches place the amps on burled cocobola in a Cypress flamed wood box with blacksand you import from Hawaii.Put the amp inside on the burled cocobola atop the black sand. Then add as many layersof iso damp as it takes from the and the walls to fill the chamber. Now here is the tricky part put the power cord through the hole the cork or corks left remember to attach the ICs from the pre and the speaker cables from the amp. Thus the three holes. Now get a small tackle and pully, fork lift etc or six strong friends to place the cement cover on top which . At this point you will once again beable to say nomore of those wretched vibrations to worry about.
