I respectfully disagree...well not THAT respectfully...in any case, I use a SS preamp with a tube power amp simply because I want the cleanest and most accurate possible signal going to my Greasefest Overdrive Special power amp where it's electrons are blasted about by various cathodes and anodes before eventually reaching my fat head in the form of happy little music blobs.Hmmmm, wouldn't the same philosophy apply to not having tubes in the amp? If you want the cleanest and most accurate possible signal, then why not an SS amp as well?
My own experience is that I can get far more 3D performance with a high performance tube preamp than with the tube amp which for me comes later as such works best with my Electrostatic speakers. And the result with that preamp alone gives me far more accurate results than any number of highly rated/awarded SS preamps that I have tried.
