Even though I responding to a forum over 11 years old I have to super disagree about the Bryston 4B. I once owned a 4B for a few months and recently purchased a Perreaux Prisma 350 stereo power amp and the Perreaux smoked the Bryston in overall sound quality and overall build quality. Look inside a Perreaux and then look in a 4B and if you can't see how much better the Perreaux is well then get a Technician to help you. This recent purchase of the Perreaux is one of the best purchase I have ever made in the past twenty years. I seriously doubt I'll ever sell this amp. I almost never buy power amps new, but this time I wanted a new one, and the only one to buy new that made the most sense was the Perreaux and it was worth every penny. I am a Perreaux fan for life and I think all you audiophiles should look into this amp.
