I wish Bryston would issue a 575HT or 675 HT. 75 watts per channel would be more than adequate for my center and surround speakers set @ 80hz crossover. Add to it a 4B-SST2 for my L/R and you have a perfect 7 channel amp system.
A 5 or 6 channel version would save me some cash and keep me from looking at less expensive alternatives for my surround upgrade.
I had a Classe' CAV-75 driving my center and surrounds about 10 years ago and I loved it, never felt like I needed more power. I would be very interested in a 5 or 6 channel version of the Bryston 875HT.
