Rediscovering records

Inconsistency in pressings has always been a problem. Be it classical or rock or jazz. Much better luck with digital in most cases.
But when you have a good pressing it sounds good. I have the original DG Brahms and Beethoven symphonies box sets with Karajan and they sound great. To me these are exceptions, not the rule. You have to research what pressing to get irrespective of genre. There’s a lot of garbage circulating on a new and used vinyl market. 
All the bad or mediocre sounding records…when you come across one in your collection, sell it. With high quality streaming setup in your system it’s hardly worth a bother. 

I thought this post was all about vinyl?

Read the question.

Best practice is to keep the discussion pure, unpolluted with other formats?

”Rediscovering records” is brief enough to avoid misunderstanding.

​​​​​​Frustration with poor quality used vinyl overrated by sellers was one of the reasons that I got out of vinyl a few years ago. Also, some remastering is poor. You do have to be selective. However, pressings seem to be more consistent these days. Phil Hobbs of Linn Records said recently that plants are getting better at using the correct temperatures.

I totally agree about turntable upgrades taking vinyl to a whole new level. That's one of the reasons I got back into vinyl last year with a much upgraded version of the same model that I had before (bearing, power supply and phono stage). I am getting more out of it now. It has become my main source again.

I have a great used record store in Dallas, Jose Records, buy all my previously loved vinyl there. I can inspect each album. Also find the Jazz, Classical and Blues vinyl is usually in better condition than Rock albums. I buy rock albums new...

Yes, I was really delighted when I heard how much, much better my good sounding records sounded when I got a whole new setup.  
BUT, mediocre records, of which I have a majority, although better than before, did not benefit nearly as much.  I don’t think they justify the expense of really good equipment.  
Im really very happy, with the great sound of the good ones though.
