My first serious speaker in the mid 70s. Bought second hand, used with a Pioneer SA 7300, which drove them well for my domestic use.
Having also had AR2ax, AR16 and AR6, I must say that the unassuming, pleasant and coherent voice of the 4x was, in retrospect, my preferred one.
I now have another pair, very old, but it still sounds as good as I remember. Modern designs offer much more, of course, but a pair of these in good health can really make music.
I tried them with a Naim Nait 3 and the match was very very enjoyable. No very deep bass, but balance and good timbres. Nice speakers.
