Another agreement; I have purchased new vinyl that was either physically flawed or reflective of a mediocre mix.
Other than QA flaws, some pressings are just better than others; hence the genesis of Betterecords.com. My first reaction was who’d pay the prices they ask for used vinyl? After trying a couple of their curated selection, I can concur they sell some really good pressings that out perform the best half-speed masters or special editions. I guess the advantage / disadvantage of higher end rigs is that you’ll know if you have a strong recording and know if you don’t.
