vinyl has a warmer sound primarily because it's analog and has defects and traits that the human ear can notice. digital, otoh, lacks those defects (and traits) and the sound can be almost clinically clean. i do believe, however, that a lot of this happens during the actual playback--if the record player's pickup wasn't mechanical, i suspect we might react differently to that, too--so storing the LP masters digitally does not necessarily change that.
