I am asking this question with all honesty. I currently use Behringer EP4000 pro amps to run my speakers - of which I have a few: B&W N805, Merlin TSM, Harbeth SHL-5, PSB Imagine B. I like to switch around which speaker I listen to.
I am considering upgrading my amp section to Bryston 4B ST or 4B Pro. My questions are:
1. Since my Behringers are rated to be 650w at 8 Ohm, what improvements could I hope to achieve by switching to Bryston?
2. Between the 4B ST and the 4B Pro, is there a sonic difference? I don't mind pro cosmetics / I know the pro has a gain dial. Anything I would be missing by going pro or is it just a cosmetic choice?
I understand warranty, build quality and resale value are better with Bryston but I'm really interested in the sonic differences.
