Hi Terry: I think I follow Simon's, Uncle Dave's, and Bluesplayer's line of thinking here. Apparently certain sounds that rely on stereo samples and/or dsp efx (particularly the Yamaha Grand Piano) get screwed up (via phase cancelation?) when mixed together to a single output (L/R+L) or via L & R outputs to a Y connector.

I realize that connecting a single PA speaker to just the keyboard's R output only provides half the stereo signal , but believe it or not, the resulting sound is actually a lot better, than if I connect it to the L/R+L output jack instead.

Terry: Are you suggesting that using a Y connector plugged to both the R and L output jacks will sound different than connecting my PA speaker to the (L/R+L) jack alone? I would think the output results would be identical.

The BIG question to PSR2000 owners. Which way do you guys prefer (for best sounding results) to connect a single PA speaker to your keyboard?

1) R Output
2) L/L+R Output
3) Y connector to R and L/L+R Output
