Hello, thesoundguy,
I can't speak to reissue product since that's not in my control. However the reject buttton for that is, or at least shoud be, in the hands of the artist. If they don't hear they're albums being ruined there's nothing that can be done.
However, guys like myself, presumeably you as well, should be in the driver's seat when it comes to mastering our mixes. If a mastering engineer smashed my mix, either he'd fix it or another one will be hired. Of all the guys I've worked with, Sax, Marino, Grundman, Collins, Hall, Marcussen, Weinberg, and Ludwig, NONE of them would take a good mix and squash it to death...at least that's my experience. If I heard a smashed album coming out of their den, I'd imagine it was that way when they got it. If one of them did a reissue and squashed it, then you're right. Guilty as charged. But my feeling is that the pressure for this kind of sound has not been a result of squashed reissues forcing the hand of current mixes to be mixed in kind. Its the other way around. Current trends, as bad as they are, are driving the reissues so when they are played, the stand up to modern levels.
I believe if we mixers can start making the change, the reissues will follow. Don't think for a minute that the squash masters of today are mixing that way so they can compete with a 20 year old reissue.
