the point is not whether there's analogue tape hiss on abbey road. of course there is, as is the case on lots of pre-ddd cd/lp recordings. rather, does it interfere with your enjoyment of the music? one of the things some audiophiles like to do is try through repeated playings to pick up background conversations on recordings like "jazz at that pawnshop." guess if you get off on that then it might be important to listen for analogue tape artifacts. frankly, i'd prefer kickin' back and letting the music move me.
