Summary: 

Some time Bob Carver concluded that the superior musicality and imaging
of moving coil cartridges (relative to CD's) were caused by the MCs'
overemphasis of the L-R signal and a dip in response near 5 kHz.

The L-R (difference signal) overemphasis improves the imaging in many
cases (a poor man's Sinoc Hologram).  A reduction in the 5 kHz region
often improves musicality; I often make the same adjustment myself with
an EQ.

The result of observations was the "Digital Time Lens" which allows a
CD to sound as an LP.  I doubt the DTL adds sufficient noise and
distortion to make a complete simulation, but nobody's perfect.

What has been interesting to note is the improvement in FM sound
quality when CD's replace LP's.  Like most classical FM stations,
KYTE-FM, 101.1 is not as fastidious as WFMT in caring for its records.
But, you can't make a CD sound fuzzy by mistreating it.  The CD either
plays right or it obvioulsy doesn't.  The superior S/N of most CD's
permits the usual compression without raising rumble, hiss, and scratch
to 50% modulation during quiet passages.

BTW, for a smooth sounding CD, try a Hungaroton CD of Les Preludes (HCD
12446-2).
