I'm not technically proficient enough to say. But my ears and mind have said a really nice preamp, can bring out the best of an amplifier going through Pi speakers. Solid state or tubed. I use both. And they are equally graced with better sound using a really good preamp. Watts and what's feeding it? Great design. Really makes a difference to me. I use Transcendent Sound preamps and either Hafler or Transcendent Sound OTL tube amps.
