Oh, yes. Our Technics top-loading CD players had a light that indicated
pre-emphasis. Assuming the players didn't properly handle that eq, that
could be what contributed to my perception. But CD was then a new sonic
paradigm, and something to adjust to.
Tom - thanks for the article.

The Denon CDs almost all produced up to when Denon stopped producing CDs
used pre-emphasis at 50/15 µS time constant giving a treble lift of some +10
dB at 10 kHz.
Almost every device for playing these type of CD´s available today
completely ignores the pre-emphasis flag in the CD data stream so this type
of CD will be reproduced with a 10 dB treble lift and will indeed sound very
hard and glassy.
When reproduced as intended with the appropriate de-emphasis the Denon Disks
sound very good indeed.
