Take it from experts.

A couple of excerpts:
The phonograph record is a marvelous medium for storing
and reproducing sound. With frequency response from 7 Hz
to 25kHz and over 75 dB dynamic range possible, it is
capable of startling realism. Its ability to convey a
sense of space, that is width and depth of sound stage,
with a degree of openness and airiness, is unrivaled by
anything but the most esoteric digital systems.

The idea of clean bass from vinyl much below 100Hz is generally a fantasy.

Two words: tone arm resonance.

Next limitation: treble. You can put as much treble on a
DAT or CD as you want. Unfortunately this is not true on
a record (or analog tape for that matter). Although
25kHz response is possible, excessive transients are a
problem. There are several reasons for this. It was
decided with the advent of the first electrical
transcription phonograph record, to reduce bass and
boost treble in the cutting of the master record.

It so happens that many CDs have entirely excessive,
forward and harsh treble. Coincidence?

Just goes to show that some people who do mastering and mixing are short on
taste. The CD format has uniform power bandwidth over the audible range, so
unlike vinyl it puts no constraints on making recordings with lots of
treble.
