vs. Straight, unprocessed music.

Seriously... it's yet another case of missing the obvious, by habit of overthinking during analysis. Placing my ear close to my left front speaker, and switching between Straight and 9-channel on the A2010, there is no difference in that speaker's volume whatsoever. Not sure why I expected that in going from 2.2 speakers to 5.2, the addition of three speakers would not add any amplitude to the overall level of sound... but I obviously did.
Apparently, though... your assessment that the real culprit is the processing
that the 9-channel mode adds, is correct. It's just that from reading its description in the user manual, I got no indication that such would be the case.
Anyway, after performing your ear-to-speaker test -- which I will hereafter always refer to as the "amplitude crawl"
-- I then compared the Straight mode's output to the output of all of the various "unprocessed surround decoder" modes, while seated in my Listening Position. Prior to today's experiments, I suppose I just refused to believe that the surround "decoder" modes were somehow "unprocessed" (especially since each one of the modes produces a distinctly different sound), while at the same time believing that the 9-channel mode is
Interestingly... I discovered that while it's true that switching between the various decoder modes does produce individually discernible sound "shapes"... all of their volume levels remain exactly the same as the "Straight" volume level.
Conclusion? No more 9-channel. About an hour's worth of mixed-genre playback has me settled on Neo:6 Music mode for all of my non-critical 2-channel music listening.THANK YOU
