I previously owned a BP-25 mated with my 4B-ST and while it was dead quiet and brutally revealing it was too sterile for my tastes. A Rogue 66 tube preamp warmed everything up nicely. I had spoken at length with Bryston before my first foray into tubes and their opinion was that tubes do in fact color the sound but I made the leap anyways... In my system the analogy (using televisions) would be that the BP-25 was a HDTV black & white set - you could see everything in complete sharpness but the subject matter was sterile - the Rogue while less detailed offered color and was in the end more enjoyable.
Tube preamp for Bryston 7B-ST
I'm thinking about switching out my Bryston BP-25 preamp to a tube preamp. While my bass is solid, the midrange can sound congested with dense musical material. There are a number of choices with great reviews. Please help! I'd love to hear about your experiences combining tubes with SS amps, especially the 7B-ST's. Thanks in advance.
