I go to hamfests often; if I ever need old audio gear, I can get it there (recently picked up a home-built crystal set with the galena cat-whisker still hooked up - I have yet to try to see if I can get it to work, but it looks complete).

Not too long back I bought a bluetooth adapter for my old Realistic component stereo system (that I bought as a high-schooler in 1989) - my wife likes to use it to listen to music and audio books, both inside the house and outside on the back patio.

If I ever wanted to do some kind of "streaming music/speaker system" - there are plenty of open source options out there. Or I would run wiring for speakers like others here have done. But for now, our needs and simple, and we're fine with that.
