	CX encoded disks........

The CX (compatible expansion) scheme turned out to be somewhat
of a fraud. Even the non-audiophiles could tell that the claims
were stretching the truth: that is, the system was

1) NOT compatible - they claimed that if you played a CX encoded
   disk without the decoder, it would sound just fine. Wrong.
   It sounds like shit.

2) Dynamic range expansion & noise reduction - to some extent
   this did take place, but not to the degree claimed. They
   also didn't mention the side effects, i.e. pumping, breathing,
   phase distortions, etc.

So CX was a marketing gimmick to aid an ailing record industry.
(Sort of like the current gimmick becoming so widespread...)
