I played something that looks like the XE1 quite a few years ago at Fox's music in the UK. The organ sounds being Hammond were very good but the styles and other sounds were very lacking in the quality department.
It was also very expensive at the time, far more expensive than a Tyros 2 is today.
If these are new instruments then I hope they sound better, but to me it looks exactly the same as I sat down and played for a hour.
