Since I first posted this question (almost four years ago) I have experimented with a lot of different Beatles titles. IMHO the best sounding are the original (1st pressing if you can) mono Parlophone's from the UK...... They are hard to find (and even harder to find a deal on), but it's kinda fun to track them down. In the end, I really like these better than the MFSL or Japanese pressings I have.
