I have read these posts at somewhat a distance as the only experience I have with Bryston was many years ago, like 15 years ago. But I am compelled to chime in because this thread has seemed to turn into a, mine is better than yours, thread and much of it based on warranty.
There is no denying that Brystons warranty is one of the best, if not the best, in the business, which I commend them for; but this has nothing to do with the sonic performance of their gear, nor the fact that they are in many night clubs, which is a target market for Bryston.
As someone who recently purchased two MF pieces, I will simply state that I am very happy and I could mention many other testimonials/quotes. In like manner you will find many happy Bryston owners and testimonials. But it still boils down to, for the original poster, which of the two amps will work best for them and can anyone with experience with both give their thoughts, I dont have this experience nor has anyone in the above posts.
From things I have read, it is my opinion that you have chosen two fine amps and I can understand your curiosity. Sorry I dont have more to offer between the two but I find some of the comments in these threads to do you a disservice, not that they are not entitled to their opinions. Having my own, I feel MF is generally very good gear for the dollar.
