Never heard the Bryston, nor the CODA No 11. I do know that CODA amps are huge current machines and deliver a good chunk of that power in Class A..I know the CODA No 8 well, and own the latest S5.5.
The S5.5 drives some very difficult speakers extremely well (vintage Infinity RS Kappa 7s and Thiel 2.3s) among others.....but I would think the Coda No. 11 could be a good match
