Both amp are great and I did have a hard time when I chose them few years ago. Bryston has one thing no other company can beat them is their warranty. It makes resale and buyer from used market more confident to purchase or sale them. I personally and finally own the Classe CA201 after a long and hard decision, I like more on Classe even it is not pure class A like the old Classe few years ago. They are rated class AB. Classe have better authority on mid and lower bass and smoother on midrange and warm sound. It is a bit laid back. On other hands, Bryston has a touch grainy on midrange, brighter sound. I have a pair of Maggies so I found out Classe suit up for Maggies, Martin Logan more than Bryston. Bryston really made my Maggies sound brighter and more grainy and glare compare to Classe. Finally is your taste of music, I find Bryston suit more for rock, pop, some classical, movies sound track, Classe is better for jazz, vocal, string instrument.
The Classe won in my case is also on its look from inside to outside, "wife acceptance" on Classe is better than Bryston. Classe do take quite a lot of time to burn in. It took me almost 400 hrs, after then it is a big reward. Good luck
