First a couple of snarky answers: (1) they listened to music, (2) nothing, because none of us used the term "audiophile" in those days. Enjoyed a Sony RTR machine for years, later a Nakamichi 1000 that my brother and I bought jointly (used, because they were so darned expensive!). Added a dox noise reduction unit later on; pretty darned good results for the era. That equipment is long gone, although I still have a couple hundred cassettes in the closet.
