This is kind of embarrassing, but I have the MCA 1688 pressing. It's one of those nice-price re-issues that has the $uper-$tars $uper-$avings circles printed into the album cover. It has AA 1006 scratched in the dead wax. It's probably worthless junk to the true record collector. I'm just a record listener, not a collector, and even when I try to obtain the best copy, I feel like I am throwing darts.

Anyway I think my copy sounds pretty good. I just listened to it today. It is a little bit thick and tubby for Steely Dan, and it's sort of dark sounding compared to the 1999 CD remaster (that's all I have to compare it to). I guess you could say it is a little dynamically polite (compressed for radio or mid fi?), but it's really not a bad sounding record. Overall, I think it sounds better than the CD remaster.
Maybe I will buy the new remastered version to see what I'm missing. I hate to own three copies of the same album but sometimes you just have to try it for yourself to really understand the differences. (Sometimes? More like all the time.

)
BTW, terry, I really enjoyed that you tube video. I don't think I caught the fingers on the snare sound you described, (and I can't hear that on my copies of AJa either) but I do hear the basic groove on that tune.
