Best Isolation HRS? SRA? Zoethecus? Symposium?

I use a non-audiophile rack, too. Depending on the configuration of your shelves, Ken Lyon at Greater Ranges can custom build Neuance shelves to fit your rack. I use one for my digital source, and Ken custom made it to fit my Salamander cabinet.

I also use Symposium Rollerblocks and Aurios. Aurios are used in laboratories to isolate sensitive measuring/testing equipment. So, as far as passing the real world test, Aurios have the pedigree.

Frankly, I don't know that I can hear a difference using this stuff, but I figure they can't hurt.

I second Jtinn. Try also apex & formula shelf!!

For me, the choice wasn't even close. I opted for Silent Running Audio's Craz rack and Ohio Class XL+ isolation platforms, and haven't looked back. IMHO, there's nothing better on the market, and that includes Grand Prix Audio. The secret is that each platform, and each shelf on the rack, is designed specifically for the component it supports. Now that SRA is accepting trade-ins for old platforms, and offer new support pads for the rack shelves FREE OF CHARGE, it's no longer a monetary hassle when you change components. I could've bought any rack out there, and I chose SRA. It's a no-compromise solution--the best of the best, IMO.

I have three Critical Mass bases. Two, which I have owned for about 5 months, sit under Joule Rite Of Passage amps. The third is nearly 2 months old, used to isolate my preamp. I have seen no change in level. The product is aesthetically top-grade, and so far, the construction has proven to be as well.

Hooper: What is your experience with the Grand Prix Audio for you to say that? You know I know both peices extremely well and for Janson's situation I would have to lean toward the Grand Prix Audio.
