Wow, I just picked up some Antique Sound Labs Tube gear and was using some paradigm Atom's. Sounded great, until last night I hooked up my B&W 303's (still fairly low end speakers) and WOW amazing! On Solid state amplification (I have a denon 4800) I didn't really find the B&W's had enough extension down low and were not really all that great. But with the tubes WOW let me tell you whole new world! Does anyone else use B&W with tubes? I'm now wondering what a CDM or Natilus would sound like!
