Well let’s see. My ARC SP9 mkll still works perfectly and it’s from 1987. My Acoustat speakers from the eighties still sound great. My Pioneer tuner from the eighties still works and sounds great. My B&O Beogram 1900 from the seventies needs to be cleaned and lubed. By your logic,I guess I should toss it and buy a new one. Oh I did toss my Sony professional CD player from the early nineties, but that was because it was from a small run of only a few thousand units and I couldn’t get parts!
