Keith,

I've found this thread very interesting and am now convinced that 
"wavy" and "swimmy" sound involves out of phase effects such as you 
get at the rear of an M-S setup.

A little bit of out-of-phase can enhance an acoustic, but it can 
rapidly become too much and sound "swimmy". In particular this happens 
with M-S because, as soon as you get wider that the "sweet area" where 
M<S, the stereo image goes out of phase.

The "sweetener mic" in the quote above restores M>S especially when 
delays on digital mixers can make the sounds coincident.
