Where does one place AQ sorbogel feet?


I got 3 AQ sorbogel Big feet. These are supposed to reduce mechanical vibration by absorbing energy and releasing it as negligable heat. My question is where under the cdp or amp do I put them. Everyone seems to use them in threes and there are 4 feet. Do I place 2 on the insides of the front feet and 1 between the back feet? Does the flat side face down or up? What do I use to protect cdp and contact points (theyre sticky)? Anyone have experience with these and how do they sound? Thanks in advance!

If you are going to use just 3, then find the heaviest point of your component, and place them there; the lightest point gets the the other. Usually, the heaviest point will be where the transformer is. Also, put a heavy book on top of the cdp; it will further dampen vibrations. BTW, I would stay away from steel/brass cones; they seem to offer better resolution, but highs have been distorted in my experience.
Now you have 2 positions to trap the noise,top and bottom. No exit to escape from..

This is untrue. All dampening devices affect some frequencies more than others. To expect otherwise would be to expect a material to react identically to differing energy inputs, which is clearly impossible. Sorbothane's website has detailed and specific data on the quite frequency-dependent effects of different sizes, shapes and durometers.

That said, Sorbothane can certainly cause problems as well as solve them. Using the appropriate Sorbothane product beneath the feet of my A/V cabinet yielded significant audible benefits with no downside. That tweak was an easy keeper, as were the four Sorbogel feet beneath my turntable. OTOH, Sorbothane feet beneath my speakers (B&W N803 on a carpeted wood floor) were an instant music-killer. Took those things out of there and put 'em back in the drawer.

Like all tweaks, listen with care and don't be afraid to give them up if they don't work.
Dougdeacon, Sorbothane is a frequency absorber and a damper. Which selected mechanical frequency did you choose to alter that did not change the frequency before or after the fundamental? By changing the Q did you not squelch the dynamic structure? All dampening devices are also storage devices. So how much was absorbed and how are you to predict the time and selective frequency to be released?
