Tube Preamp Isolation


Currently using Vibrapod cone/isolater combo under my Music Reference RM5 MKIII. I've got it on a Billy Bags rack. I've got an Audio Research LS15 on the way and am wondering what you guys use (if anything) under your tube preamp?

I just installed some 3M damping sheets in my Belles 21 that I bought thru AMUSICDIRECT.COM $20 for a set of 4, very cost effective IMO and I can hear a difference. I mounted them inside the removable top of the pre. I also use Vibrapods as well.
I have tried lots of things. And as my system changes so does the isolation.

Right now using Dh cones Jumbo's. But have also used symposium rollerblocks, symposium svelte shelf, and Symposium fat padz.

It's also on a Arcici suspese rack.

The rolleblocks bring out the detail, lower the noise floor, but at a expense of some warmth. DH cones keep the warmth... but don't seem to lower the noise floor much.

The symposium shelfs and padz are somewhere inbetween...
