if you check the last page of that same review you will find:
"JVC DLA-RS10 Projector: Pros
* The best black levels of any projector we have worked with, at any price. (Just slightly better than the RS2 it replaces, which was the former black level champ)"
and from the CIR engineering review:
"For my money, if I hadn't bought a projector yet and was considering the Radiance, I would probably opt for the RS10 instead."
just food for thought.
