Any Bryston 4B3 amp owners out there?


I'm strongly considering a 4B3 amp purchase. Bryston's warranty and build quality are as good as it gets and the price is in my budget. Pro reviews are good, I'm just wondering what owners may think. Are you pleased with the performance, what it's matched with, etc. I'm already aware of the specs, the story behind the design, and all the press release stuff. Plain talk would be appreciated.

Thanks

I'm having a great time with all of these responses and I'm getting FIRSTHAND (no reiteration of press releases) appraisals. That's what I had hoped for. For those of you that have shared what you've experienced in your system with Bryston, shared what your system consists of, and make comparisons to other notable amps, I'm especially attentive. It's all but a done deal, the 4B3 will be in my home for at least a test drive. I can try it for 30 days for the cost of return shipping if I don't like. By most accounts, it sounds like a risk worth taking.
Having owned multiple models of Bryston amps over the years and more recently a 4B3 I can say this is a wonderful amp and clearly a more evolved design than its' predecessors.That said,pairing with a quality tube pre amp is essential in providing that deeper richer musical experience and touch of romance.
I had a 4bst with my original Magnepan MGIIIs and loved it.  Since then upgraded to 3.7s with MC452 then Sanders Magtech, then to 20.7s and replaced the Magtech with a 4b3.  The 4b3 is the best of all of them by far. 
I too have been a Bryston amp owner for quite some time. I bought my first one (3B) in the mid 80's. It is now in my son's system, and still running strong. I've owned a number of 4B's and am currently running a pair of 28 squared. I have not had the opportunity to have the cubed version of the 28's in my system, and am curious as to what sonic differences I would notice, but that's another story. The Bryston quality of build, and the longevity of their products speak volumes. As for the tonal qualities, that is purely subjective to each of us, but hopefully the OP has purchased the right "match" for his system, and taste. I would hope the OP will keep us posted as to his conclusions, once he has had the amp in service for a while. Cheers !!
I have a couple of 4b sst2's - I like them very much but there is one thing that bugs me - at somewhat high volumes they begin to clip. I am using an anthem avm60 and they both clip when I am up to around -10db which is nowhere near the max of +10db. Not sure if anyone else has experienced this. Apart from that though they sound fantastic.

BTW have you considered the Mcintosh MC302? I need another 300W stereo amp and have been thinking about getting the 302. I've heard that is sounds detailed, warm and lush which is the sound I'm going for..
