> The crappy CDs were a result of dumping a phono mastering onto a CD without realizing that a CD player was not going to apply the RIAA curve.

I don't believe this is the case. The RIAA curve is a very aggressive curve (40db) and no one would tolerate an uncorrected signal (plug your turntable into the line in for a taste, all you hear is sibilance). Also the filter would be applied by the person mastering the vinyl - it would not be applied before the master tape.

IMO the thin sounding CDs were because producers were used to vinyl which still has issues with bass even with the RIAA curve in place. Also because CDs were new and we lacked the knowledge and tools to use them to their potential. For example my teachers in college would have me turn in my DAT tapes with peak levels around -18db (late 90's).
