In 1974 I was in the Navy and had a WestPac friend get me a Sansui Eight Deluxe and I chose the Acoustic Research AR 3a speakers, which supposedly haven’t aged well.
I recall looking at a range of speakers including KLH, JBL, Advent, Bose, Klipsch, etc. Japanese speakers weren’t an option I considered.
At the time the large Advents were the best bang for the buck and I listened to a pair of friend’s small Advents many enjoyable hours.
