I have nothing but good things to say about Bryston. Their MO is not to be the latest new thing, but to carefully refine their designs and bring only real improvements to their products.
The Cubed series is a step up from the previous line. It's the quietest amp I've ever used and is supremely neutral. I have the 3B3 Pro because that's as much power as I need. The fact that it's 35lbs and fits in my rack is a big bonus. But the larger ones are still easier to handle than most high end amps. The Pro version has trim pots on the back to match my preamp gain better.
My interactions with Bryston were excellent. I received replies to any questions within hours and the responses were on point. I also had great service from my dealer during the transaction and follow up afterwards.
