I agree with Fran. There is no question about the superior samples and the live sound being more pronounced. Some like the more homogenized sound, but other than sound Ketron suffers from a much smaller marketing impact, and perceived reliability issues. Personally, I have the Audya 76, as well as the SD40 and SD2. I find all to be great.

OTOH, for quieter settings, I find my S970 fits the bill, so I can see why many like the Genos ans SX900.
