Yeah, the 1990 ones are no-noised a bit, while the 2001 ones are EQ'd. Of the two-fers I'd go with the 1990 ones if only for the lack of harshness; the best way to hear the 1960s albums is actually the Pastmasters series. No EQ, straight from the master tapes.
T.R.B.B.
The Pastmaster series -- is that the Japanese Toshiba series?
Yeah, with unsteady azimuth on "Do You Wanna Dance".
