“Up to spec”.
Considering that there is a weak relationship between specs and SQ in the view of many members of this forum, the promise is no panacea for owners hoping their old amps will sound like new. Just sayin’…
Bryston's New Back To The Future Program.
According to James Tanner if you have a Bryston amp over 20 years old and out of warranty they will bring it up to spec. Also you will get a 3 year warranty. At the present time it's only available in North America. He also mentioned that if successful he may consider older Bryston preamps. No prices were given.
