Recommend good isolation

Not cheap, but not horrible expensive : Herbie's products. 90-day guarantee, money back. Always worked for me, sometimes *really really* well, brought out the best in my best gear. Email Steve Herbelin and ask for a suggestion if you like, he's been right on the money in my case.

Tobias, I second Herbie's products and great advice.
I use their tube dampers and the lampblack spheres under my tube amps.

I highly recommend you try 3 cheap Myrtle Wood blocks under each component, and listen to the difference between that sound and the Vibrapod sound. That may help you decide which way to go, as there are multiple approaches to consider. I always found the wood footers superior to the rubberized footers.

For a total investment of less than $10 I find this isolation technique works extremely well. Go to Walmart and buy a few 3 ball packages of Penn racquetballs. Go to their drapery department and buy a package of wood drapery rings with a 1 3/8ths inch opening. Remove the metal screw/clip portion from the drapery ring. Place 4 drapery rings on the self under were the four component corners will be positioned. Put a racquetball in the middle of each ring. Place the component directly on top of the racquetballs. You can easily feel the difference this makes by putting one hand on the component shelf and rapping the shelf underneath it with your other hand. You will likely feel considerable vibration. Now put your hand on top of the component and rap the shelf beneath it with your other hand. You will probably not feel any vibration. Heavier components may require the use of additional balls. If anyone tries this and likes the results I would like to hear from you. Good luck!

Sorbagel, what Grand Prix Audio uses to isolate their shelves!!!! Works great under CDP's and pre's. at very reasonable prices on E-Bay. GPA #3 or #4 cones under the CDP works well also.
