The short answer is it changes from day to day.
The shop usually just gets the news or a movie thrown on the 55" or the local 70/80/90's FM radio station (though a vintage Akai AA-930 receiver and some huge "disco era" towers), but a typical listening playlist for me goes something like this:
Turntables are a Dual 1229Q and a Dual 1249. Both rebuilt by myself and I made the oak stands they are in. Still have to stain and urethane them. They feed into a Sansui 8080DB and out to some AR4x speakers.
I tend to prefer vintage Sansui gear. There’s also a set of Sansui SS-35 studio monitor headphones and Sansui SDM-1 mics. But I won’t turn down vinrage gear in good shape and theres even some vintage Pioneer and Luxman stuff hanging around in my storage room. One of my favs is a set of Pioneer Monitor 10 studio headphones. You can see a couple Radio shack "Hi-ball" mics next to the 8080DB as well. the ubiquitous "garage band" mics from my youth....I won't say I often plug them in and sing along, at least I won't admit it publicly....
There's also a couple cassette players and a Sony 50 CD jukebox for when I’m doing housework instead of just listening.
I have a decent vinyl library, but not huge by any means:
More than enough there to satisfy my listening “wants” as its all music I selected so its all music I like.
The sound from this setup is fantastic and this is my "forever" rig. Plenty of power for me at 85 WPC. The sound is crystal clear and warm (I rebuilt the 8080DB a few years back; caps, transistors, etc) but it will shake the windows anytime I want. I don't though, that's just way too loud for me these days. Well, maybe once in a while.....
It will leave my hands when they have my estate sale.
Yeah, I'm pretty much an 80's guy when it comes to music and a 70’s guy when it comes to audio gear...
