After reading the replies, here is the final tally:

Integrated Tube Amp: 4
Tube Preamp/Solid State Amp: 3
Solid State Preamp/Tube amp: 1
Sold State Only: 1

I guess this just goes to show how subjective the listening experience can be. However, after reading the responses (Thank you all, by the way), I think I'm going to go 100% tube. Then, I can go back to SS if I feel either power or precision is lacking.

The only way to see if I can hear the "tube difference" is by buying or auditioning in the area. Anyone with a tube amp from Boston.............
