No it does not destroy the "coding" of the stereo mix as intended. I think new things that folks have not tried, especially when they are older tend to frighten them. Not that you are old, I have no idea, but you are settled into thinking or worrying that something is destroyed with four speakers. You really have no clue about recording events. I have no clue either. There are simply too many variables, too many different mixed recordings, etc. for anyone to know that front center and just behind that is a wonderful jazz band playing in RVG's living room. This could be true, and it could also be false, it really depends. I seem to be the only talking about on-axis listening and how to get the most out of that. And the analogy of 4 speakers to headphone listening, one would think others would pick up on that virtue. Both on-axis and headphone listening fly in the face of stereo coding being destroyed, and scenes appearing behind the sound field but only with two speakers.
