I bought an RQ-J9 BEFORE reading this post. One of my favorite s by the way. Love the early Panasonic line. But boy did the J9 have problems. Unbalanced signals between left and right, lots of wow and flutter....lots and lots of motor buzz in the headphones. It was in perfect cosmetic condition but luckily I could return it. NOW my daily driver is then RX-S35 which I LOVE! Love this post and all the great photos. Fantastic collection you have!
