Cleaning won't help a bad pressing. Buying 300 other records says nothing about this one. Even buying this same record and having it be good won't really tell us anything conclusive. Because with 2 samples one noisy one quiet 50/50 still doesn't tell us which one is the norm. That is why I said you only have to return it one to 5 times to find out.
The same has always been true, but back in the day there never were any records, at least not that I ever saw, that were as bad as what I have seen today. In the last several years I have seen bits of paper melted into the vinyl, dips so severe they cannot be tracked, noise so uniformly bad it intrudes even when the music is loud, warps so bad even my clamp won't flatten, and on and on. Back in the day we thought a tick or pop was worth a return. By that standard almost nothing today is a keeper.
I know now someone will tell us how wonderful dead silent flat hot stamper yada yada yada their last 5 million new records were.
Yay! Happy for you.
