Recommend good isolation

Cheap, Chemical rubber bottle stoppers. Size 10 cost about $1 up to $1.50
I got mine (I have about 4 dozen) at American Science and surplus.
Everything I own sits on them. Even doubled up, with an 8 on top of a ten set, for my SP-15 pre.

When thinking 'isolation' more then the 'pad' needs to be addressed. One of the most overlooked issues with isolation is the amount of acoustic engery that is flying around in a typical listening room. So, think of ways to 'acoustical' shield all your equipment. Few do this and miss an opportunity to bring their listening experience to a new level. The most important component that needs this 'shielding' is the turntabel/arm/cartridge. Often putting it in an adjcent space works best.

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.
