Won't speak about the music, it's obviously incredible! Will however give my first impressions of the remaster. I've been excited for ages about the release of the Remastered Beatles albums and was taken aback to find Abbey Road in my local Morrisons 2 days before the official release date! (Spoils John Lennon's superstition about the number 9 somewhat). I've been flipping between the old and new cds to see how big the differences are. It is instantly apparent that there is a new crispness, detail and depth that hadn't been there before. It's as if the instruments and vocals are more clearly separated with no blurring between the lines. Lying on the floor with your eyes closed and with a set of good headphones, you can almost look around within the sound and see the individual lines playing only to you.
On first comparing the old and new copies the first thing that strikes you is the volume, noticeably a couple of notches louder on the new remaster. The old one is certainly flatter in contrast and almost distorted in its blurring of detail.
However, don't get me wrong, these differences are quite subtle. It's a big difference in some ways, but I'd say the majority of people won't really appreciate it. A bit like comparing a DVD to a Blu Ray, yes you can see it's crisper, but you remember the film, not how sharp it looked or even how big your screen is!
For a true fan that knows every note and sound on everything they ever released, like myself, I love it. I revel in the genius the whole process was. Writing, arranging, performing and recording it doesn't get better than The Beatles. This will remind you how good it all was in better definition on a digital format then ever before. It's been a long long....long time coming, but this is probably as good as you'll hear it. In my head, it was always this good anyway.
