Genos produce stereo big time.
In fact, also at many 'right hand' sounds, when use headset or G speakers you can hear clearly how the sound move from left to right or opposite, a sort of 'follow the keys direction' when play.
But, I stand by what I said in other threads.
When play gigs for hundreds of dancing people, the noise from tapping and stepping shoes, people in motion and people talking, no other than yourself would notice or care less if it's in stereo or not.
