No idea what was played on 'em,.... it was in '76.
I had a friend, who knew the owners of a local appliance store,one day he told a couple of us,about their new "sound room" where the salesman would close the door and crank it up for potential customers.
Well, 3-4 of us went down there,. and we were introduced to "Denny", and he had Klipsch K-horns,La Scala, and Hersey speakers. He then put something on,.turned it up,. and left the room. I was hooked! A few minutes later,..he was back,.. he may have played the others,. don't remember,. we talked $$$. Of course,the K-horns were outta a 20-21 yr. old price range,besides being too big,.. I wanted the La Scala.... but still too big/expensive,... the Hersey looked like a little brother to the La Scala,. with the tweeter and midrange horns, and with a loan,.. I could afford 'em!
After taking them to a couple of parties, then stopping,couple of my friends ended up buying their own.
That store is still there,only sell furniture now
