I have found this to be true, as well.  My best disc transfers use the ELP
with custom filters to reproduce the RIAA (or other) curve.  The CD vs.
digitally-mastered LP restoration comparisons are very telling.  On
occasion, because the ELP is so flat (especially down low), I am forced to
use a high-pass filter on the final file to minimize rumble from the
*cutting* unit.

Yes.  Also, master tapes can simply degrade to the point that the original
LP sounds better than the digital transfer of a master tape would.  Sad,
but true.  There are numerous examples in print right now.
