McIntosh MC402 vs. Bryston 4B SST

Can anyone enlighten me on the differences between these two amps and how to make a good decision between the two. Other than the obvious price differences which I may exclude from my decision making process and I believe there is also a big difference in warranty. I guess I am more concerned with the differences in sound and listening quality? I have always heard about how great McIntosh's are and had wanted to get one since I originally heard about them, but now I see that the Bryston is highly rated, but how does it stack up to the Mac - or does it stack up at all?

Thank you in advance - confused in the northeast
