Knowing if a record will sound good is tough these days. You can read discogs reviews but those are a crapshoot because 90% of them are people who are listening on $50 turntables with built in 2” speakers. They either complain about everything being shit while ignorant of their garbage equipment or paradoxically just think everything is 5 stars because “vinyl just sounds better”

That said the steve Hoffman forums music forums (stevehoffman.tv), gearspace.com, vinylengine.com, certain subreddits (forget which, don’t really go on Reddit anymore but r/vinyl is probably a good start) are at least places with more nuanced discussion where you can generally see the rationale for why someone thinks a pressing is good instead of just “omg it sounds so good 5 stars”. You often get great info on their signal chain as well. But they aren’t nearly as comprehensive so don’t expect to find everything
