If you think that even the SST amps still have that typical Bryston highs (a smidge aggressive) then the Choke change is what's needed. I had my 14B-SST done a few months back at the Peterborough location and I am very happy with the outcome. I will also add that IMHO the BP-26 may be a better match for a Bryston amp with the new ouputs than in the past but again this is only my opinion (BTW I use an ARC LS-26)...
Bryston 7B SST
Bryston is offering to update existing Bryston 7B SST amp output stages to the latest "C" configuration used in the newest and very highly-reviewed 28B monoblocks for $250 per amp plus shipping. All new 7B SST's will have the "C" configuration. Has anyone had any experience with the new "choke" output stage in 7B SST amps? I use my 2004 vintage 7B SST's with very revealing Merlin VSM mme speakers and have heard that the update gives the 7B SST's a gorgeous top end.
