Hi Alsi
I would say that there is effectively no difference between the 808 and the Cine 8.
Cine 8 has horizontal RGB bandwith to 120 mhz, 808 - 110 mhz
Cine 8 has vertical RGB bandwidth 37 - 210, 808 - 37 - 200
These differences are inconsequential IMO.
Barco may argue that you are getting a more recent model, with refined internal electronics and perhaps upgraded components.
And don't forget the Cine 8 is painted that cool silver colour!
I suspect that the differences are largely in the cosmetics and marketing of the projector.
