Bryston Amp Experience Needed

Reserve power usually gives better dynamics and punch. I have a 4b3 and a pair of 28b3 monoblocks.  The 4b3 would be a great choice for you with power and great sound. This is a very quiet amp, quiet sections of music retain detail with the low noise floor which is so important. I have no regrets with my 4b3. I would not sacrifice the power.

Thanks for all the input/info so far, it's a great help.  Some are asking the sensitivy of the KEF R11's.  Here ya go.

Sensitivity (2.83V/1m) 90dB

Try an NAD M22 v2. 300wpc and “load invariant”.  Yes it’s Hybrid Digital but KR from Stereophile loved it and he’s heard a lot. To me it competes with the 4B3. And it’s in your comfort zone. 

Hello, 
I think your Emotiva amp is H-class and the Bryston is A/B or an exceptional D. I tried the Emotiva and went back to the A/B. We had a discussion about power a few days ago. If your speakers are somewhat efficient You would be more than fine with the 200W. I am using a 100W Marsh Sound Design and it blows away the Emotiva you have sonically. Plus if I were to turn it way up I would go deaf with my 100W. There can be an issue if you cannot utilize the power it does not sound as good as a lower wattage amp. If I were pushing Thiel speakers or a low sensitive speaker I would take the higher wattage. You could spend that $1000 on something else like a better DAC or cartridge. I wish you could test both so you could hear the difference. 

I think you should be fine with the 3B3. You say that you generally listen at low (or at least not crazy high) volumes. So you should have enough headroom to handle transients and dynamics. Would the 4B3 be better? Yes. But is it worth financial strain? No. Get your 3B3 and enjoy it. When you are financially ready to move up you can sell the Bryston 3B3 as the used Bryston market is active.
