I have a 40-year old amp and speakers at home. My dad’s old stereo. Works fine, but it has so much static buzz.
Sounds great though. I’m just a bit hesitant to leave it powered on all the time which means I don’t use it much compared to my Bluetooth speakers. Old power supplies are not very efficient. They can get hot. There is also a decent amount of dust. And then there is the risk of some old cap blowing.
