Jim:
Forgot one thing......based upon my experience I have found absolutely wonderful benefits with tubes using good isolation and dampers. I am currently using Townshend Seismic Sinks (need one more for my pre) and Herbie's Tube Dampers everywhere there is a bottle. The benefits of the Sink under my tube DAC was absolutely eye opening. Can't speak for your equipment in terms of reaction to dampers, but in my pre (a PSE HL1) the improvement wrought by putting the Herbies Dampers on a pair of Holland Bugle Boys was really dramatic.
