he sent this back to me to paste here for you to read -
((Hi Ray,
I don't read that board, but please copy/paste this response:

This is not correct. There are a few things:
1. The stereo set was *not* compressed in its entirety. There are some tracks
to which no compression was applied, and others where compression was only
applied to one channel (typically, the one with the most transients). In
general, the amount of compression/limiting typically resulted in a volume
boost in the range of 1db-3db. Less than 1.5db of compression gain in not
audible. There are a couple of issues with the stereo set, but the compression
isn't a big one.
2. There was no compression applied to the Mono set. None. You can try to
determine this through comparisons with other masterings or vinyl pressings,
but you will get incorrect results. Those masterings will may appear to have
higher transients in some instances due to the amount of EQ that was applied
at the frequencies dominant in the transients. EQ was not (as far as I know)
applied to the Mono set. These were done flat.
3. As a final consideration, keep in mind that the original mixes (especially
the mono mixes) were heavily compressed and limited. It many cases, the
limiting was rather extreme. Revolver is a good example of this. If they
applied 1db-3dbs of further compression, it would be virtually unnoticeable,
as all of the peaks were already squashed. It is the same as bein upset that
somebody drew on your blue wall with a blue crayon of the same shade. ))
