It seems you are on fire again, Jim Although your reasoning MAY BE correct it seems to suffer from a logical fallacy, the one of "hasty generalization". Yes, we should keep our eyes and ears open to the possibility that their speech is a strategy to increase sales, but what they say makes sense to me (and beside that, don't they have a money back guarantee?): a single system is not well adapted to work with effect tuned sounds (like stereo piano sounds). Of course their choice of words to explain the issue is kind of hard (the other guys are guilty), but that's understandeable and does not allow me to draw any quick conclusions about their official speech strategy. I'm really badly anxious to have the opportunity to audition and A/B test it with my current PA, in Europe. That'll be the final judgement. BTW, I have asked myself (before this discussion was brought up) about the reason my Kurzweil synth has mono piano samples when the stereo samples sound so good on a stereo system...
