Tube Preamp Isolation suggestions


Good day all.
I was hoping for some suggestions from folks who have expereince with various isolation tweeks fro tubed pre amps.

I 've done a good amount of research concerning products like mapleshade, SRA, harmonix, shun mook, symposium, stillpoints etc. but have no practical expereince with these products in terms of tubed pre's. Any help would be appreciated!!

Thanks in advance

You will get as many different opinions as there are audiogoners. I like the Symposium Rollerblocks, especially with the tungsten balls. I've tried many different isolation devices and these seem to work the best. I also place a pair of 5 lb. coated lead scuba weights on top of my tube pre-amp.

I still believe the old adage that you isolate your component from a less stable platform and couple it to a more stable platform. One thing that works really well is to use air to isolate components, i.e. small inner tubes. When I was in graduate school we had some very sensitive equipment that needed to be isolated from airborne and furniture-borne vibrations, and using inner tubes from wheelbarrows worked the best of anything we tried. There are now some commercial air platforms on the market.
