Whether they have cut corners or not is debatable, it may have been inherent in the design all along...I simply think 99% of the users play them through stereo speakers and don't notice it.

We must remember that most of the users are home players, and any extra speakers they use will more than likely be a home stereo or something similar.

I seem to remember the PSR-8000 I took over a buddy's place one time, and played through his Traynor KB-100 combo keyboard amp, which was mono, sounding a bit less than the way it did at my home through my stereo setup.

Another thing I've noticed in recent years, is that keyboard amplifiers are going stereo...the mono Traynor KB-100. for instance, was replaced by the stereo K4, the Roland KC-350/550 offer stereo expansion, and the KC-880 is stereo, so they must be doing this for a reason...someone is noticing that a lot of keyboards sound better in stereo...hence the demand for these amps.
