What happened to Q. C. anyway.This has been discussed on the forum. Many of these pressing plants are new startups and can’t keep up with the demand.
QC on new production vinyl is terrible. Compromises are made in the rush to get the product out the door. In addition, there is a level of inexperience; there are no maestros of vinyl pressing and processing as there were in days of old when vinyl ruled the roost.
With regard to warped records, not enough drying time is allotted. An entire batch of records will have the same flaws and a given vendor may receive many of these units.
It's a shame that after a century of pressing records and technological advances that we have to resort to using a record flattener.
If all these warped records are being returned to the dealers and/or distributors, you would think they could make a better product.
