Like any product class, some are better than others. I have vinyl from the 50s that holds its own against MFSL and SuperDisk stuff from the 70s & 80s. I've also a picked up some new pressings like Chick Corea's The Vigil and St. Vincent's Strange Mercy and find them fully the equal of the old stuff. And, all eras are subject to warps, off-center spindle holes, inclusions and all the other defects too. You pays your money and takes your chances. Happy listening!
