I read this on YPKO recently...interesting opinion about the Atelier.
If these are the same organs on the Atelier site, they do sound great, but hardly better than a properly set up G70 (which is not a bad thing, mind you!)..the "Articulated" voices were standouts, but not in the same league as Tyros3's SA1/SA2.
One would really have to think long and hard considering their prices.
Of course, like you, that's just my own personal opinion and observation.
