You really need all three sources, Vinyl, Disc and Streaming. If you have the room, and the patience, tape players work, too. Reel, Cassette and 8-Track. Sadly, I have all of those, plus Laser-Disc, AM-FM Tuner, XM Tuner and VHS. Not all in the same place, mind you. I still have to hook up that Quadraphonic system, too. LOL!
