It may be worth inquiring how the non-HDCD was recorded, though I don't
know if it would matter re. the tests you're planning. [as a side note,
i believe what I signed up for at reference recordings is a list for
new releases, as there are no instructions for posting to the list.]

In this* thread, charles hanson (ayre research dir) takes issue with
the use of a separate A/D converter in the original sampler:

" The most egregious example of this was when they released their
sampler that allegedly compared non-HDCD against HDCD. What they
negelected to tell you was that the non-HDCD track was made using the
(atrocious sounding) Sony 1630 A/D converter and the HDCD track was
made with the (excellent sounding) Keith Johnson A/D converter. This
was an unfair, depceptive "comparison". "

There's a lot of other info in there, but the thread is hard to read.
