The Motion Sound amps come with a spatial expander. I've heard that they have an uncanny effect of making it seem like the speakers are farther apart. Without the expander, the speakers are tilted at what appears to be a 25 degree angle from eachother, and I heard that the stereo signal is pretty good without the expander.

I purchased the Motion Sound KP-100S, two 8 inch speakers and 50 watts per channel. It's coming out in April. I will give a review of it when I get it. The KP-200S, two 10" speakers and 100 watts per channel, got a great review in February's keyboard magazine.
