Bringing Bryston 4B back to 1997 new.

Thank you for your detailed response. I’m right behind you age wise. Lately I’ve been reading about  purifi amplifiers and what looks like an novel new way of amplification. Up till now nothing has come along that I thought was significantly better. I know the restored Bryston will be a great amplifier for many more years. To me it’s similar to current car choices. The Bryston in my mind would be like a Lexus. Smooth and reliable and a little luxury. Where the new D class amplifiers compare to a Tesla. More cutting edge,wave of the future.

Bryston doesn’t change existing circuitry . They do update caps and filters if they can. It will still be the same amplifier as it was when it was when manufactured. I’m not likely to be spending $7400 for the cube series.
