There are fanboys of every company out there. I don't have a whole Bryston rig, but am working towards it. Why? Because nothing I've heard is better than the BDA-1 for the money. If it had a Bose logo on it, I'd
almost feel the same way

Aside from sound quality, you can't argue Bryston's build quality and support. A friend sent back his 20+ year old amp and Bryston updated it to near current specs for a couple hundred dollars. Far better than it was, not that there was anything wrong with it in the first place. Very few companies will look at anything out of warranty, let alone 2 decades old. In addition to that, everything they did to it is warranteed for 20 years. Who else can make that claim? They quoted me $125 to bring my 10 year old integrated amp up to current specs.
Then there's James Tanner who hangs out here and listens to his customers and all their insanity. He's tracked down orders, helped with setup, and so much more. Aside from the very small mom and pop operations like Red Wine and Van Alstine, who does this?
In the tube vs solid state debate, both sides are right and wrong IMO. Tubes aren't inherantly better or worse at anything. Its not the technology, its the implementation IMO. Audio Research, BAT, and McIntosh (among a lot of others) do a great job with tubes. I don't think they're better or worse than Bryston, just different.
If I had the money and rooms for it all, I'd have BAT and Mac systems in addition to a Bryston system.
