I will be doing this along with my preout measurements when I get my other mic back from dayton. My rundown will be:
-Measure Sub out and create a cal file showing low-end rolloff
-Measure L/R outs in Pure, direct, and stereo with and without any DSP
-Measure Audyssey and non Audyssey speaker responses
I will document all of this with overlays and separate graphs.
I can't wait to see your results.
I find distinct change in imaging and a bit brighter presentation with the 7.1 analog inputs going from Pure Direct to Direct.
It should be measurable.
