The most common reason is that because vinyl records don't have a flat
response, vinyl has a preempahsis applied to the HF.  Sometimes the
preemphasis was applied during cutting, sometimes it was applied to
the tape master before cutting.  When early CDs were pressed, they
were often pressed from the vinyl masters and if the preemphasis was
on the master, boom, harsh gritty super-over-bright CD.
