Aurios under JC1 monoblock's?

Some interesting responses here...

Tvad, as much as I appreciate the offer, I think I'm gonna pass. But I did read all the info on Symposium's website, very comprehensive. I had never really looked into them before. But the more I read and research, it sounds as if there would be a very negligible improvement, if any. Perhaps that money would be better spent in cabling and/or power conditioning for my source, I don't know. It's quite a stellar system, IMO, just trying to squeeze every last ounce out of it and make it the best it can be. It certainly couldn't hurt to try some of the cheaper alternatives though, such as the rubber/cork sandwiches that Clio09 mentions. And I read all the info on the Cat/Tiger Paws, very interesting. They would look way cool under my amps, but they sound like they could be a bit cumbersome to use, and they're a little pricy, IMO.

Still not sure what "ringing" glass means and/or it's effects on my system, if any. Ever seen that compressed rubber high density flooring used in commercial applications? I have samples of that at home. I think I'll try cutting some small squares of it and slip them between the feet on my amps and the glass and see if I can discern any effect.
Maybe this will give me some insight as to what direction, if any, to take...

You're welcome, and I agree.

Perfectionist - the rubber pieces may actually be an interesting discovery for you. One thing about rubber though from what I have learned, is that the durometer rating could play a factor. Products like sorbothane or the rubber-based dampening products you can find at McMaster-Carr work differently based on durometer rating and the load placed on them. I recently had a friend test the rubberized material used in the HRS damping plates and he found it to have a durometer rating of 40. So he sent me some plain old rubber squares with the same rating to see how it might work on various components (top covers and underneath). I'm in the process of trying them out now so we'll see what happens.

Speaking of McMaster-Carr, can anyone provide a link to 5/8" Tungsten Carbide balls like those used by Aurios and Symposium?

Tvad - I'm not sure if this is going to take you where you need to go, but:

http://www.mcmaster.com/

If it is not a direct link, then type in "carbide balls" (sans parentheses) in the search box. When the navigation tree pops up on the left select Tungsten Carbide Balls, then Precision Grade 25..., then you size.
