Good preamp match for Bryston 4B ST

I had one of these and I had it paired with a Bryston BP25 with moving coil phono preamp. This was a solid pairing and formed a synergy. I see there is a bp5 with MC section for sale on the 'gon. This would be a good value.

I connected the pre and power amp with balanced Synergistic cables and the 4BST powered Thiel 7s at the time I had this system. Wish I'd kept the 7s but that's another story.

My thoughts around synergy are not so much sonic as they are from a design standpoint, where the manufacturer optimized the output of the BP25MC specifically for their ST series of amps. I had no experience with other preamps, except for a brief audition with a CJ 17 preamp in that system; the results were very "sweet" sounding but I lost the dynamic punch that the BP25 had. Certinly this is one of the quietest combinations I've ever had. Quality cables were a must, and I also tried Tara Labs, I liked the Synergistic more. Another contender for a quality solid state preamp at a bargain price, unless you're sold on tubes, is Parasound's JC2.
