Good preamp match for Bryston 4B ST


In process of upgrading. Currently have Bryston 4B ST, Dali Halicon 400 MkI speakers, and Rotel 1072 CD player. Listen to mainly acoustic music of all styles and prefer uncolored, if somewhat warm, musical sound with good imaging and soundstage. Already over budget a bit; would appreciate suggestions for a compatible preamp under $1K used.
Thanks in advance for any suggestions.

I used to own a Bryston 4B ST. The input imedance is 50 kOhms, which by today's standards is an easy load for most preamps. My favorite preamp mated with the 4B ST was an Audible Illusions Modulus 3A, which you might find used within your budget. The Modulus 3A will flesh out the sound of the Bryston a bit over comparably priced solid state preamps, without sounding colored like some tube preamps. At the time I owned the Bryston, I also tried out Bryston, Quick Silver, Balanced Audio Technology, and various passive preamps. The Audible Illusions was the best fit of the bunch.

I'm finding myself leaning towards a tube pre, with at least four inputs (ideally including phono), also ideally with at least remote volume. One reason I'm inclined to go with tubes is that the high end on the Dalis (dual tweeters) is quite intense and can sound a bit harsh with some instruments. Overall, I love them, but I want to make the best pre match here. For all this, of course, I'm willing to stretch the budget some. Aljordan, the 3A sounds interesting, I wish it had a remote. Which Bryston did you try? Stevecham, could you say more about the "synergy" with the BP25. Any other thoughts would be appreciated. Thank you all very much. Rick
