Pass Labs XA30.8

@panerai557 specifically with respect to your question on the difference in sound character between your existing Bryston 4B3 and a Pass XA30.8, the design goals of the two companies are different. If you like the way Bryston sounds, you may not like the way Pass sounds. And vice versa. I think it would be misleading to say going from one to the other gets you more of something, or is a general improvement, as opposed to what I would instead describe as changing the direction of your sound.

Panerai557, have you considered trying the Wide Angle
version of HFT?

I can't imagine you'd have any troubles driving those speakers with the XA30.8, especially at the listening levels that you indicated you prefer.  People seem to forget that doubling your wattage only increases to volume by 3dB.
