soundings,
As has been already pointed out, your suggestion is inherently flawed.
Switching to one speaker only lowers the volume and in any case changes the acoustic relationship with the listeners. It says nothing at all about "speakers being with or against" one another. (Unless for instance speakers are wired out of phase which can cause some gross, annoying effects to the ear. But that of course is diagnosed by having the speakers playing at the same time).
People get "emotion" from their systems in any countless number of configurations - from a laptop, to a car stereo, to all the ways different audiophiles have their systems set up. I own various speakers that I position in various ways in my room, and I, and my guests, all get in to the sound from all of them.
Now, of course low distortion vs higher distortion is associated with an ease to sound, and how loud it may be comfortable for a person to turn a system up. That’s well known and nothing new.
But your particular example doesn’t seem to offer anything helpful or illuminating in this regard.
Any more wisdom to pass along? ;-)
