I wouldn't say I "hate" the 60s stereo mixes. I prefer some of them to their mono counterparts (BFS, Help!, MMT, White Album). AHDN is good in stereo too, and most of Revolver. But what I've said is true, and people who worked on those albums have admitted so. When The Beatles started to attend mixing sessions, they only assisted to mono sessions, with a few exceptions, what does that tell you? Or the fact that George Martin didn't go back to pre-bounced tapes for better stereo mixing, or the fact that he arranged the twin track recordings with the mono mix in mind, preventing a well balanced stereo of those albums to ever exist. The little care can be seen in blatant mistakes like Eleanor Rigby or If I Fell. Many of those stereo mixes are also unbalanced.
