Best vibration tweaks


The components in my system rest on a Lovan rack (not filled). Until recently, I hadn't considered doing much more to control vibrations in my system. But I've noticed that their are some relatively inexpensive (a dangerous phrase in our hobby) tweaks in this department that are available. I'm curious to know what experience others have had with things like Vibrapods, filling their stands with weighted material, airmats, Audiopoints (?), those half-globe gel balls (don't know their name), etc. If you've tried them, how much of an improvement (if any) did they make? Several of these appear to be mutually exclusive, so which do you recommend most? Thanks for your input.

Just a couple of general comments to add to this thread. There are two broad approaches to handling vibration: isolation, and control/absorption. Isolation techniques include things like cones and spikes (when you want to either anchor the item, or keep it from introducing vibration into the system), whereas control/absorption through the use of sorbotane, Vibrapods, NAVCOM, springs (turntable suspensions) etc., reduces the amount of energy being picked up by a component. Both methods are effective, but have essentially different approaches. Often, you will need a combination of both to eliminate the majority of vibrational energy.
dude, do it cheap. cut tennis balls in half and mount your components on them, then, unless you need to keep the top panel clear, put a concrete slab (approx. 8x12 inches) on top. see if it improves the sound. if not then you can spend the bigger bucks on fancy materials.
worked for me.
I'm about to throw away three 12.5" bike inner tubes filled with mineral oil, since I've found something I think beats them and is hugely easier. Make a shallow tray, say, 20" x 15", with sides 2" high. The bottom should be hard. Make a plywood sheet 19" x 14", and nine small marbles and three broccoli rubber bands. On the bottom, place three marbles each within the three rubber bands and locate these in an equilateral triangle on the bottom of the tray. Place the plywood sheet on top and your component on it. Variations are possible, but the general idea should have come across.
someone over at the atma-sphere users site suggested using butcher blocks for absorption devices. 'cheap' too. i think they'd be especially good used under a turntable with cones. check this site out:

i've been told they'll cut to spec. i'm calling tomorrow. if enough of us call asking about the potential absorption characteristics of these butcher blocks when used in an audiophile context they're going to start hanging up on us so be careful ;-)
Kubla, Are they throwing in a set of steak knives with each purchase? If so write me down for two.
