I think that everyone has missed a critical point in the reissue game. Many tapes from 30-40 years ago and older have degraded to the point that you can run them through a pure tube mastering chain like Tim de Paravicini's and it really won't help a bit. Add to that many masters being lost and the reissue folks are working from thrird and fourth generation safety masters which likewise have degraded.
Much of this stuff is gone for good, due to poor storage and volatile tape formulations and all the wishing in the world is not going to bring it back.
