What did you do with bad recordings on LP? I can think of countless LPs where either the recording or the pressing were so poor that it distracted from the musical performance.
You've received a good suggestion about looking for remasters. (Of course the reverse can be true. Sometimes the original mixes are better than the remasters. A friend had a "Yes" LP he loved and bought the CD which he thought was terrible. We solved the problem by my converting the LP version to CD for him.)
However, it is simply a fact of life that many recordings are mediocre and a few are just downright bad. At that point you have to decide whether the music is more important to you than the recording quality.
