Any Bryston 4B3 amp owners out there?

I have the iconic Krell FPB 300cx, purchased new in 2001. It’s a Class A amp and does an excellent job driving my Dyanudio Confidence C2 speakers. The sound is glorious and while I’m not looking to make a move today, I AM looking to at some near future point consider a new , more powerful amp as my speakers can take anything I throw at them. My new home has a larger room so I’d benefit from more raw power, so I have my sights set on the big brother Bryston - the 14B3. With that said, I auditioned the 4B3 and the dealer happened to ALSO be a Dyanudio dealer and got to listen to this 4B3 with my exact same speakers and a preamp not as good as my Krell Foundation. There was no sub bass in the demo, while I have a large Rel sub bass in my system. To Beysron’s credit,  I have to say I was more than a little impressed. The Bryston sounded virtually as good as my Krell.  300wpc v 300wpc and if my capacitors all burned out tomorrow I wouldn’t hesitate at all to purchase the 14B3. Sonically the two should sound the same with of course the primary difference being in power and headroom. But the sonic properties virtually identical. Always best to audition if possible. I imagine there must be a Bryston dealer in your area for an audition? 

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 !!
