I have an old (late 1970's models) stereo system that consists of an Akai 1730D-SS Reel to Reel, Technics SL-Q3 Record Player, Marantz ST-2020 Stereo Tuner, Nikko NA-550 Integrated Amplifier, Pioneer CT-F500 Stereo Cassette Tape Deck and a Spectro Acoustics 2102 Graphic Equalizer. I'm interested in buying some headphones, ideally from the late 70's as well, to use with it. I would love some advice, I don't know much about headphones or compatibility issues... Any input would be appreciated
