Thanks, Dave, for the quick response. I think I'll just take the simpler approach and use a single keyboard amp. However, I still wonder about the inputs/outputs. I mean, the output from the left channel of the ASR-10 isn't the same as the output from the right channel (or is it?), so, won't it sound different trhough an amplifier, depending upon which ASR-10 output the signal is coming from? I know the amp's going to produce a monaural output (sound), and this will make the ASR-10 sound a bit flat to the listener.

Maybe the powered stereo speakers are a better idea, but I tried this once before, with a pair of Sony powered speakers. There was no sound produced by the speakers at all, so evidently, I need a preamplifier between the ASR-10 and the powered stereo speakers, right?
