I will also share a hugely positive and recent experience. Purchased a pair of second hand 7B SST 2 units to replace a McIntosh MC 302 that was simply too bulky and heavy for me to manage anymore. When I received them, the original shipping cartons were pretty beat up and the speaker cable binding posts had cracked plastic knurls. Sent Bryston an email with serial numbers and asked how much it would be to purchase replacements and how long it would take. They sent the binding posts with detailed replacement instructions at no charge the next day and the replacement cartons the same day I gave them my CC.
Replacing the binding posts was a piece of cake and the cartons ensure that the next time I have to move the amps my experience will be trouble-free. The superb response of a company expertly and proudly supporting superseded gear guarantees I will keep them at the top of my go-to list for electronics. It's for precisely that reason that Dynavector, McIntosh and SOTA remain go-to manufacturers for me.
Lots of folks here frequently fret over corporate consolidation and The End Of The Audio World As We Know It. My experiences lead me to believe most higher-end companies rely on positive word-of-mouth to build sales and can go to unusual lengths to make sure that impression is substantiated irrespective of venture capital intrusions. All of the companies I note above have done so and 3 of them multiple times over 15+ years. In the case of Dynavector, it's been since I purchased my first Karat 23 Ruby back in the early 80s. Bryston is the newest addition to that enviable group.
We just have to remember this is a hobby first for everyone involved. If we treat our fellow hobbyists with respect and give them the information they need to know to help us, they will respond as best they're able. Everyone wants happy listening. We need only give those who support that goal the courtesy to provide it.
