I'm not sure how many here are aware of, or have heard this box set, but if you haven't and you consider yourself a "hardcore" Beatles fan, you must. They, in my opinion at least, absolutely sound better than the 2009 Remasters. Amazing quality. Getting your hands on the actual vinyl would probably cost you more than $1,000, but there is a rip out there by a guy called Dr. Robert of the entire series to 24 bit/96khz FLAC and they sound amazing.
If you're a huge Beatles fan, you MUST hear these.
