RE: Class ab amps

IMHO too many people get hung up on amplifier class of operation. There are excellent and not so great sounding amps across nearly all classes. Some will insist that Class A is the best sounding so they pair their under powered HOT running Class A amp with a speaker that requires more power and the sound is compressed or congested. They would have been better off with a good Class AB amp with more power. I've been there myself! I'm at the other end of the spectrum running Class D these days.

As for Bryston, I auditioned a 4B series amp back in the 1990's then bought Classe instead ;-) I much preferred the Classe sound. Bryston back in the 90's sounded harsh and grainy to me to go along with their thin and cold sound. The more recent 7BSST2 pair that I had was better. They weren't harsh or grainy but still on the lean thin and cold side for me. I prefer more "meat on the bones" and a warmer more robust and "musical" sounds.

My Pass Labs Aleph 3 from years ago:

This true Class A 30-wpc amp runs HOT and draws nearly 250-Watts from the AC mains. Coupled to my reasonably easy to drive Tannoy Definition D500 towers the setup sounded dynamically compressed and congested. Even the modestly easy Tannoys require more power. The photo was staged but you get the point ;-)
