Your best option will always be private torrent sites in my opinion. Usenet is cumbersome and requires usually at least two paid subscriptions. One for the Usenet server and one for the indexer you use to find your warez on Usenet. Soulseek, edonkey et al will get you music but tags and quality will be all over the place.
Troll around on tracker threads either here but most likely on reddit for open invites. Use an open invite to talk on the forums on that site and they usually have invite threads on there. Go from a open sign up to a closed private site with a little patience and a little time.
A little bit of irony. Vinyl are mixed differently and never fell victim to the “turn it up to 11 for radio era” of mixing because the physical medium can’t do what digital can. So while you may not like the pops when they happen in a rip you are actually getting a more balanced mix. Don’t believe me, listen to them side by side.
