They're all good, Don, but I can definitely hear the difference in each keyboard's tuning, EQs, etc. Personally, I enjoyed the S-970 the best, mainly because it showcased your vocals better than the SD7 and EA7. Overall, there wasn't a hill of beans difference between them all. Damned, you almost sounded as good as me with this one.

All the best,
Gary
