I have a ZZ Top Tejas Record that I got used right around 1982, so it could be an original pressing. I cleaned it up with the Audio Technica 6012 Kit and man did this album sound good. Granted is has all kinds of scratches and minimal warp. Hardly any pops and crackles. Just sounded clean.
I once again compared against my Wiim Pro Plus playing this same album in the FLAC format at 16bit/44.1Khz.
This time, the record had less bass and less high end. No Vinyl album and FLAC Album offer the same sound. Different Masters obviously. So I did some research and the orginal pressings of Tejas has less bass, where new vinyl pressing had a different master with more bass.
Funny I use to be a purist and would not touch the bass/treble knobs and still don't for that matter. Then we have so many different masters for the same album, we don't need to with the studios doing it for us.
Billy Squier's Enough is Enough has the closest master between Vinyl and FLAC that I've heard and still prefer the vinyl master. For that matter, ZZ top Tejas is the only album that doesn't sound as good as the FLAC file but stll sound pretty good for an old scratched album back from the 70s !
