How to word this...
I've had a variety of tube and SS stuff with my Klipsch.
McIntosh MC-30's
McIntosh MC-2102
Wright 2A3 (pair)
Transcendent SE-OTL (pair)
Quad II (pair)
Jolida (??)
Viva 300B SET
Yamaha CR-2040
dbx BX-1
dbx BX-3
Crown K2
That's most of them.
Yeah, I'd say there were some sonic differences but the differences weren't black/white different... I ended up deciding for the maintainence issues, headache issues (I had a tube blow on me once), I was just as happy with SS sound and putting the extra cash in my pocket!!
So today, I have a K2 sitting on top of each (actively biamped) speaker, a K2 powering my Danley DTS-10 and the dbx BX-3 powering my LaScalas. All solid state (it sounds good AND is quiet as a church mouse with zero hum and zero fan noise)
