I just listened to my original CD of Katy Lied and the newest HD version I could find on Qobuz and there are a ton of differences. And that’s just what most of them are, differences. I really didn’t find most of the differences an improvement to the album.
And I’m in total agreement with you that AJA is a much better album in most every way.
New remastering of Steely Dan's Katy Lied review by Fremer
I don't have a turntable, but in this case, the remastered material is streamable. I did a bit of listening last night and it sounds a bit better, but it’s still far short of Aja, so there’s a let-down effect. “It sounds better” is not the sonic experience of “Wow, this is amazing.”
Still, better is better, and I'll settle for better.
