So I've been very intrigued with the Mastered For iTunes suite and I spent last night listening to samples of some Elton John albums available and comparing them to my CD rips (256 AAC). While in an ideal world I'd love to have ALAC, I did notice a difference. It was subtle, but noticeable, and most notably, I've noticed more dynamic range. I was wondering if any of you have also noticed a difference and in which ways? It seems all of the articles I've come across have been about the technical underpinnings of how they're doing this, which is interesting. But at the end of the day: how does it sound?
