big difference for me, is im hearing all sorts of flaws in the recordings i was having a hard time hearing before..... every little edit, cough, chair bump, and gnat fart is painfully obvious.
stereo is WIDER, mono is more centered...etc...
i have very phase sensitive ears (i cannot wear headphones without getting dizzy), so, i think thats what's causing my "fatigue"
but, im very happy. (except about the part where i blew up one module)
