In ONE word . . . NO !
I 'of COURSE' tested this out and compared going out my Tyros to the KP-100S vs going out to a single EV SxA100 speaker, and the KP-100S sound wins "hands down".
Donny: I'm really surprised

at your question considering the fact that I thought I had gone over this in detail in several other threads. In addition, I would have thought that especially since you had the opportunity to audition the KP-100S in a store that the salesman would have highlighted the Motion Sound unique stereo benefits as well.
In a nutshell: Stereo keyboard output (L/R) mixed & sent to a single mono speaker output (such as a single EV SxA100) results in degraded sound due to stereo efx phase cancellation. The KP-200S & KP-100S speakers were designed to completely eliminate this problem.
