Ron, I have not yet received the remaster of EITS, so I can't comment on that.
There is certainly no perfection with either hardware or software decoders
for every song!
It's a very long story about 2--3--5.1 channel conversions.
Gerzon, Halfner, Klipsch and others wrote papers expounding their theories/concerns
about 3 speaker fronts (Trifield , etc), quad, and eventually what we know as
multichannel processing from stereo evolved. (be it hard/software)
I can tell you these statements I believe to be factual: Hardware upconversions
to multichannel are very convenient and have the instancy required for most folks requirements, excepting
those, and I often include myself here, who do not find those conversions
adequate for music that we actually sit down and listen to.
Software conversions, while not having the immediacy of hardware logic chips,
often offer a much more satisfying soundfield, albeit time and effort is involved.
Please excuse my rambling.
