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.

Get the 565's and send them out to be modified, they will smoke just about any amp near there price. I find it hard to believe the 4bst is as powerful as the 565 'welder' despite what it says on paper compare the insides of the two, the 565 is so simple and built like a tank they weigh about 50lbs ea. so times two would make about 100lbs and the bryston weighs no where near that much, leads me to believe there is not as much to them. Granted sound quality wise the 4bst is better out of the box but the 565 has more potential.
