Primarily, only the Yamaha PSR series has had any serious accusations of a major difference between the mono out and summing the stereo outs externally. And, as of yet, to my knowledge, no-one has ever done a serious comparison of the two to find out definitively if this IS the case or not...

If I had a PSR, it would take me ten minutes to answer this question definitively. Sad that no Yamaha owners are willing to find out for sure...


I did extensive tests with at least three different Yamahas. The result was that they sound better in stereo, and they sound better when using separate outs, rather than the summed outs, when using mono. They sounded great in mono, but, to me at least, better in stereo.
The difference in the other brands is far less pronounced, if audible at all, once you get a fair distance away.
