It's along time since I've listened to a new LP, but back in the 1980s we would, as producers, be provided with test pressings to which we would listen carefully, in order to detect faults on the metal discs from which the LPs would be pressed. Often there would be much to-ing and fro-ing with the factory before satisfactory results were achieved. I can't imagine that this level of care could possibly remain in today's economic climate and 'post-industrial' world.
The other problems that exercised us with the production of LPs was that of over-modulation at the end of the side, especially if it was long, producing distortion if not handled carefully at the disc cutting stage, and excess high frequency at the original recording stage which could produce a signal that most average domestic quality record players could not easily handle. A Pablo LP that I have of a Zoot Sims date on which he plays 'Never Let Me Go' was so carelessly cut that it is almost unplayable..
