I am interested in being able to determine if one album (say the new
Faithless album) from different factories have different sonic
characteristics - especially if the sound is compressed to sound good
on lesser systems.


If you want to look at 'pressing quality' you need a Plextor Premium CD-RW
and PlexTools Pro software (free with drive).

If you mean "recording quality" then want you are wanting to do is pretty
bizzare. There is no effort involved in getting essentially identical data
onto a CD from completely disparate manufacturers. And even if not, it is
not going to show up as a different in frequency response or dymanics. Disc
manufacturers do not remaster the music.

For those differences you are looking at different *mastering* of the same
mix, or completely different mixes. Again, CD factories are not where the
mastering happens, , if their QC is dodgy, it aint going to show up in a
spectrum analyser.
