What isolation feet to use??

Bright Star Audio Isonodes are very good for the money. However, one word of caution with the Isonodes - and many other "soft" footers, such as vibrapods - is that they may damage furniture finishes in some cases. I have also had good luck with the Herbies products and have found them safe with furniture finishes, but buyer beware on all such products.

Rakuennow: If you're a good enough engineer to figure out how they work, I would hope you'd also be good enough to be able to put them back together.

Though if you actually try them in your system, you may not want to send them back!

Cruz128, good advice. And not just wood furniture. I used some Vibrapods on top of an amp once and they etched permanent circles into the metal surface. Never again.

I like the Grand Prix Auadio Apex and they don't have to be used only in a GPA rack.

I'm using the Herbie's products also with excellent results. Using the iso cups under every component. Using Brass gyro's at the CD player and preamp. Lampblack balls under the amps and voltage conditioner. Have also tried the ruby gyro's. Using tender feet in my HT system.
