Yes, I would prefer high powered tube or hybrid amp. However, ideally I would have two different systems. One system is a compromise too. The music I listen to varies from acoustic guitar and vocal to world music to jazz fusion. The amp doesn't have to be insanely powerful, just great 100 watts and efficient enough speakers. For medium size room this would be just right.
Symphonic Line I might try too later if I can find it, or older Gryphon, before I go with tubes or Lamm hybrid.
I appreciate your input too and understand , I think, what you are saying.
