Since there have been lots of posts about using Bryston amps with Thiel speakers, I wanted to relay my experience.
I owned Bryston 7B ST monoblocks years ago and while I thought the Brystons did a good job driving my CS3.6s, I eventually became less satisfied with the match-up. IMO, there was a lack of PRAT using the Bryston amps, and I strongly value this criterion in a system. I eventually made the decision to purchase a Naim NAP300 and have never looked back. While the Naim amp is "only" rated at 90/w/ch into 8 ohms (150 into 4), this amp has no problem driving my 3.6s to levels louder than I want to listen, and in my opinion it exerts much better control than the Bryston 7B STs did. I know there have been several new series of Bryston amps since the ST version, and I understand that each generation had improved - however - I currently have no plans to upgrade my Naim components.
Bottom line -- I just wanted to put in a good word for the Thiel-Naim match-up and throw it out there as a possibility for consideration if you're considering updating your amp.
