Bryston 4B-ST vrs Adcom 565 monos

Try a 4000 or 8000 series from Aragon. No more power concerns !!

I can't speak to the Adcom, but I have a 4BST that I use with a pair of Totem Acoustic Model One Sig's, which are also 4 ohms. The 4BST provides in excess of 400 watts into 4 ohms, and the Totems love it. I also have a pair of ProAc Response 2.5's, and a pair of ProAc Response 1SC's, but whenever I hook up the Totems I stay up until 3:30 am on work nights because I am so amazed at the sound I can't turn it off.

I currently own the Bryston 4B-ST, and about 6 years ago owned a pair of Adcom 565 monoblocks. The amps have different power ratings on paper, but actually put out nearly identical power in real-world use. However, power output is not the only issue -- the quality of the sound is even more important, and here the Bryston is far superior to the Adcom. The Bryston also has a 20-year, transferrable warranty, which is unique in the high-end audio industry.

If money is not your major concern, I'd strongly recommend the Bryston 4B-ST over the Adcom 565's.
