Thanks Fran...I never did think of the issue as "chronic"...it IS a "stereo" piano and meant to be amplified that way.

I'd say it was more of an inconvenience if one needed to use a single amp/speaker.

The Traynor K4 did solve the issue quite well...up close...it's a shame that the stereo imaging further out wasn't better...of course it is primarily a keyboard amp and not a real PA.

I appreciate your explanation.
