Sand bags under a cdp - didn't work well

Megasam: you do anything to disguise the tubes or just let 'em sit there like techno-industrial artifacts? i'm not putting you down here; i really am interested in this. BTW, my cd transport weighs roughly 47 lbs. is that too heavy for the tubes?

Try innertube under and sand on top. Cheap solutions can work. Damping pads inside the top cover might help. Dont let anyone make you think you have to spend big bucks unless you want to.

CornFB because tube is 12" diameter under most CDP you will not see it. Because you control amount of inflation with hand pump any weight CDP can be accomadated. Put just enough air in tube so CDP feet are just cleared, tube will be very squished. When you touch CDP it should sway easily.

Cornfed: You can just make a rectangle (like a picture frame) out of wood trim (or whatever) and place the tube inside so that it does not touch the sides. The top of the rectangle should also clear the bottom of the player. This is pretty much what the manufactured gizmos are like. I use a wheelbarrow tube, which is even smaller, on my two box mini sytem in the spare room. I recently tried it on my CAL player in the other system and preferred the vibrapod/platform sandwich instead. However, the tube sounds better (than the Pods) on the cheap system. I guess that you just have to try it and see if you like it. The tube muddled the mid bass and midrange on the CAL but had the opposite effect on the little system. The little system is thin walled and resonates (even after I damped it) and the CAL is built like a brick.

If the bicycle inner tubes are not working, try using one of those inflatable hemorrhoid cushions that can be bought at almost any pharmacy including Target, Walmart, CVS, etc. They are a lot wider than inner tubes and made to hold a lot of weight, i.e. your ass. I put water in mine because water is more dampaning than air. Works for me.
