A RED perhaps. What about a Hasselblad or a view camera with a Leaf back or something like that?
You cant go wrong with one of Leica's digital offerings.
Be aware that optics are costly, so whatever your no limit price point is, keep in mind the cost of additional lenses can hamper you.
If price is no object, why limit yourself to a DSLR? Better ways to go if price is no object and you are interested in the best possible quality.
