Have you numbers for the frequency response discrepancies in cheap CD
players? With one exception, all of the magazine reports I recall have
shown flat response within +-1dB from 20Hz to 20kHz, often within
+-0.25dB.  ("High Fidelity" measured the Technics SL-P7, for example,
at +-0.25dB.)

The exception, the Sony D-5 described in the December 84 "Stereo
Review", still has flatter frequency response than the $1100 Van Den
Hul moving-coil phono cartridge described in the July 84 "Audio"
(+7.5dB at 20kHz, on its way to an impressive 15dB peak at 30kHz--lock
up the dog and lock down your tweeters) or the $475 Monster Cable
Alpha-1 described in the January 1984 "Audio" (+6dB at 20kHz) or the
$1000 Ortofon MC2000 described in the December 85 "Audio" (+4dB at
20kHz, though the results were distinctly different with two different
test records--so much for the RIAA standard) or the $450 Decca Van
Den Hul (+5dB at 20kHz) or the $300 Argent 500HR (+12dB at 20kHz) or
the $20 Grado GTE+1 (-2dB at 6kHz, +4dB at 18kHz) or the $425 Talisman
Alchemist IIIS (+9dB at 20kHZ), all of the latter reviewed in a recent
issue of Stereophile.

I've deliberately picked flagrant examples, but the evidence suggests
to me that frequency response varies more widely among phonograph
cartridges--particularly the much-praised moving-coil designs--than
among CD players.

As for the paucity of titles on CD, I can only echo your complaint.
