There is more going on with reissues of thirty plus year old recordings than meets the eye. While 45 RPM pressing can, no doubt, engrave more detail on an LP, the unfortunate fact is that master tapes degrade. And this degredation is related to storage conditions, tape formulation, signal and many other factors. In any given instance will the former improvement overcome the later degredation? That remains to be seen.
I recently purchased "Thelonius Monk with John Coltrane, The Complete Riverside Recordings" on CD. And putting aside sonics and remastering issues, for a moment, in comparison to my original LPs, one can clearly hear dropouts, lots of them, and insecurity of pitch, which I ascribe to stretched tape or some other artifact of the master. In the end, it's really clear how the master has just become incredibly degraded. It doesn't speak well to our rich musical heritage.
