Ya know, I go into the hospital for some tests and everyone starts stomping on my trusty E60. All I can say is - if you ain't played one don't criticize. The E60 is not just a 76 key e50. It's certainly not a G70 either, but more importantly it's not a Yammie.
I have had a PSR2000 and 3000. They're nice boards. And I'm sure the T1, 2, 3 are just as fantastic as you say. But they're not Rolands. Simply put, I think that Roland puts out the type of board I like. It may be subjective, but as Donny says - it sounds good to my ears.
And as an aside, I just got done listening to Donny's new CD and I get to tell you I'm totally blown away. Not many of us have put out anything as professional sounding as this. NAKED or not, he sounds great!
