It also sounds fantastic despite being nearly 50 years old.
Maybe every 20 years or so it needs a bit of TLC and maybe replacing some capacitors, and then itās as good as new.
I doubt that your iPhone and your Sonos speaker will even work 10 years from now.
@thomasfuchs I have a Bryston prepro paired with a Linn amp. It must be pushing 20 years old now. It sounds phenomenal. My GF wants to replace it for something that is āeasier.ā She has no idea. lol.
