I'm quite keen to hear more on this, too. I had inquired about servicing/repairing my amps (4B-ST, 4B-NRB)... the current line from Bryston is it's $800 for a specific repair. No "general service", or "refurb/renew" programs. Frankly a bit disappointing, as I did not anticipate having to replace Bryston amps due to failures... maybe the occasional service, but at $800 per incident.... What if the initial observed issue is caused by something else... "Oops, that'll be $1,600"... "oh, hang on, power switch/de-thump - make that $2,400"... in the absence of some stated policy, I can't afford to play that game.
The Refresh/Renew program should've been great... $1,000 to bring any legacy product (amps?) up to spped, replace all the regular suspects, etc. It was advertised, but then killed. I understand that Supply chain issues have been a bear, but a lot of that has bee addressed/worked around in most industries. Not sure if/how the Axiom merger/acquisition-thingy affected it, but maybe they are more mercenary about things?
In case you hadn't gathered, I am not amongst the well-heeled who's response would be "just get a 4B-Cubed, it's a great amp".. I know it's a great amp, I'm just living in not-so-great times, and would dearly love to still listen to my music using my amazing Bryston gear... it's a venting mechanism!
