Lew,
I suppose that technically a tube being a voltage device vs. a SS device being a current device it yes will be inherently quieter from my recollection of this stuff. But tubes will lose vacuum with time as there is variation in the quality of the material used in the manufacture of the tubes, the out-gassing of the material have effects, the expansion differences in the seal of the metal pins to the glass, etc... it all causes vacuum loss with time. Then you have to look at the resistance which changes with oxidation on the metal to metal contact of the pins to the socket. I am only pointing out a series of issues that make owning anything with tubes something which I elect to avoid. You don't have to be an audiophile to be able to hear differences and having many years experience with hearing and seeing degradation (a radio which cannot hold frequency with any accuracy due to a tube in the VFO going out of spec), I prefer the alternative.
Plus, who is making tubes these days? If I am correct and maybe I am not as I don't buy any any longer other than keeping a few collectible radios running, you either find NOS originals made in the US or you find some Russian tubes or Chinese. The Russians do a good job with tubes, in fact I have some GU74B ceramic tetrodes which are excellent, but the Chinese stuff I'd totally avoid. The old NOS US tubes I'd be concerned with due to the age and vacuum issue.
All in all, I'll stick with my Anthem M1 monoblock amps (or I'd be happy to take a pair of Bryston 28B3's) and my Whest PS 30RDT SE :)
