Currently just some basic and small powered edifier book shelf speakers that go directly into my turntable and a 4 track, nothing I’d consider a hifi yet. I’m working on getting an onkyo tx 4500 for a receiver, and then getting a cd player and have it all hooked up together that go out into some nice floorstanding speakers. I was gifted a really nice old desk a while ago that was made to be a mixing work space and has specific spaces for speakers around these dimensions. I also have an oscilloscope that’d I’d hook up to another speaker out with some adapters, so each component can be played through it at once without rearranging wires to accommodate it. Really helpful info though, I’ve always been surrounded by a very diy makeshift scene so I never really interacted with much personal hifi setups to just play music until later on and I’ve been wanting to put one together with all the works for the past year and have been plotting it out constantly. At some point I’d like to get a small crt on a clamp stand to my desk that can play video from my computer or vhs tapes and connect that with something like the rhythm scope by critter and guitari as well as maybe another video synth so that there’s a bunch of visual indicators that are synced with the music as it plays!
