Hi ScottY and all:
This is very interesting. I now wonder how much of a difference this made when I was testing different speakers? I tried going out mono on the L/R jack like it's supposed to be designed for. I did this with Roland amps, EVsx100's and some others. I did not like the sound that much. As a matter of fact when I tried the EV's I thought they sounded awful.
OMG Scott !
I can FULLY understand why you were so under-impressed with the sound now.

I think Yamaha needs to issue a WARNING that going out MONO thru the L/L+R jack can GREATLY diminish the quality of the sound of instrument sounds (voices) that rely on DSP effects. If I had only judged the PSR2000 and EVs thru the L/L+R mono output, I too would have passed on the SxA100's. Thanks goodness I didn't because even if connected to the R output only, the 2000 still sounds quite impressive.
