You don’t hear much about Bryston around here because the gear performs and doesn’t have problems. I bought a BP25 preamp and 4bST amp in Y2K and had no issues in 19 1/2 years, selling them with 6 months left on the warranty.
The replacements are a BP26 preamp and 4b3 amp and the newer components are even better sounding than my previous units, in a surprising way.
If you have questions James Tanner has been there for as long as I can remember and whenever I’ve emailed an inquiry he has responded promptly. He sends emails of product reviews and owner comments on a regular basis.
