Tony,
The first sight you sent me to is showing the Genesys (Solton SG-1), the second sight you sent me to is showing the Ketron SD1. These are two different keyboards. If you want to know if the Genesys sounds as good or better than the SD1, I can't answer this question yet. I heard the keyboard in June when I was in Italy just one time, and until I get mine here in the US, I won't be able to compare the two products. My initial report after just getting back from Italy was that this was a very good sounding keyboard. I wish I could have a chip in my brain that would allow me to replay what I've been exposed to whenever I need to, but unfortunately, I can't do this and so I can't comment on sound quality until I have the keyboard in front of me again. I hope this will be soon!
