When lp records first hit, for many years great care was taken in regards to sound quality because it was a new and marketable thing and the sound is what helped sell as much as the performance. The technology needed to make good recordings was not an issue even then.
Over time as the novelty wore off record product quality became more hit or miss much as it is still today.
