Chris, I just would like to say that you've come up with
the most (perhaps only) meaningful, realistic, practical
comparison method between LP and CD that I've ever heard
of.
"

Back in the 1980s when people used to buy the LP and the
CD of the same album, play them both and compare the
results, they weren't really comparing the two media.
Instead, they were comparing the (generally quite
separate) mastering decisions--EQ, limiting, etc.--behind
the two products, plus the particular characteristics of
their LP and CD playback equipment.
"

Of course LP playback equipment varies far more in its
audible sound quality than CD playback equipment does.
But your method eliminates that variable completely, and
the mastering decisions of a commercial CD aren't a
factor, either.

A guy I work with used to work at a CD plant and from what he understands
from working there, the type of media used to deliver the master to the CD
plant could make some difference. If the media was digital, then the CD's
pressed would be exact digital copies, but if the media was analog, that
meant that what the plant got was going to be an "AAD" CD with the
additional possibility that the CD plant's analog to digital conversion
might not be as good as what could be done by a recording/mixing studio.

Once the CD's were cut, they'd sample a few and play them in both a "low
end" and a "high end" CD player. The high end CD player would actually
report error detection/correction information and a certain amount of errors
were allowed in the final product, but I think they only allowed errors
which were able to be corrected by the CD player.
