the answer is, It’s different for different people. I really good friend of mine (best man at my wedding) has a receiver and speakers from the 80’s. Nothing has been updated or changed in any way. In fact it’s been in his living room for 30 years and he’s as happy a clam. Me, I’ve been slowly upgrading my system and when I retired, I started building a totally new system. When he say the speakers, he told me I was nuts for spending “that kind of money “!
To each their own.
