I don't see how Bryston and Pass preamps are polar opposites. They're both solid state designs that seem to strive for neutrality. I certainly hear my BP6 to be very neutral, and Bob wasn't able to hear any meaningful differences with them both in his system. Now the amps may be a different story, especially when it comes to the Pass pure Class A models.
By the way, IMHO Bryston preamps are under appreciated and unfortunately get over shadowed by the amps.
