I'm 73 and I am conscious that my son will inherit my system. I know he isn't gonna bother with replacing tubes so everything needs to be solid state. He isn't going to bother with records so music needs to be on CDs. I do a lot of streaming and stream elevator music while asleep. My hifi gives me a peace, and I want to leave that peace to him. My system needs to have a small foot print so my son can take it with him wherever he moves. My interest in hifi greatly increased when I retired.
