Very thoughtful, detailed, accurate response. I thank you and will say
that you are entirely correct. My sticking points were clearly debunked
by this latest post, I will have to be sure to much more succinct from
now on, you guys don't let anyone get away with anything. I have MFSL
Sound Check and it has in phase out of phase tracks. What kind of test
should be run. I also have a RS digital SPL meter if that helps. Let
me know what to do, I'll post the results.

I do not know that disc but the specific tests on the Chesky disc I
was referring to are those which provide inphase/outofphase noise
bursts for the FR/SR or FL/SL channels. A good match between front
and rear speakers makes the phase distinction clear and decisive. A
poor match (and I do have some that are) makes the test difficult.

I meant two channel stereo
or dolby 5.1 movies - there are (quadraphonic) recordings of actual
theaters without added processing? AND what is a non compressed medium?

Non-compressed includes CDs, SACDs and DVD-As (unless the producer
chose to screw things up). It does not include any Dolby process or
any DTS process generally in use.
