I’m recently retired from an unrelated profession. We recently built a house with a 12’ x 15’ room that is working nicely for my system that includes primarily a Lumin D2 streamer, Decware Torii MK3 amp, and Harbeth M30 speakers. I’ve been into better audio equipment for about 15 years, so not really an old timer at it, but long enough to have cycled through some equipment. Much of it is still stashed in closets, along with the physical media collected since the 70s. I’m sure there will be more equipment, someday. Maybe a change back to solid state power. My musical preferences are always evolving, partially keeping up and partially digging into music from before my time.
