I don't know the Marsh, but I agree with what SdC said about the Bryston's ability to exert control and definition, yet it is very smooth, not tube like, but not rude in any way and with a great soundstage. My 4B-ST is paired with an ARC SP9-II: they pair well together, In fact if I upgraded the pre I would stay with an ARC, I like this combination a lot. (I'm driving maggies by the way).
Bryston vs Marsh
I currently have a Adcom gfa-555. I am thinking of buying a a Bryston 3bst or a Marsh 200. I have an ARC sp-9 preamp with Vandersteen 2c Spkrs. My question is would I notice a difference between tha adcom and either of the amps I mentioned and if so which is a better fit for my system?
TIA
