When I went off to college in the early 90s my dad decided to update his hi-fi system and gave me his rack of "separates" which included an Onkyo receiver, graphic EQ, tape deck, technics turntable, and Sony 5 CD changer, and a Sony R2R. I lived with 4 other guys with eclectic musical tastes so I would make a 3 hr mix tape on the R2R and then we would just let that thing run. No one at college was very familiar with R2R so it was like a vintage UFO landing in the living room for some people. The SQ was great and I loved everything about it but finding blank tape reels was (despite cassette tapes being big at the time) a challenge so I reused my minuscule stash for the 4 years of college party mixes and eventually the Sony R2R was traded in with the rest of those separates to a shop in Boulder, CO called Second Sound when I opted to upgrade after graduating.
Sometimes I think about getting a new-to-me R2R but I'm not sure I would get much use out of it these days other than as hi-fi shelf candy and conversation starter for visitors.
