Digital BW, The Print

I now have to make a choice:

I have done so much research and had so many helpful posts, but I am 
now down to a decision. I am going for the Epson 7600. This will be 
for BW printing. (If I can print colour on it too, so much the 
better, but that is a very minor consideration.) I am having trouble 
as I cannot get a test print to show me the abilities of the 
Imageprint RIP used with UC inks, Matte black and the IP profile for 
a matte paper. Basically I am working blind on that one. I have seen 
a print supplied by Cone Editions, and was very impressed with it.

I saw a print from a 2200 done with the Imageprint RIP, Lyson inks, 
and photoblack, which left me cold. Very grey looking. Apparently 
they had a profile made for this combo. Print was very sharp, just 
very grey looking.

I am looking for:
Deep rich blacks (good DMAX) and good tonal values on matte papers 
such as Hahnemuhle Photo Rag. I would like if possible, to have the 
ability to print warmer or cooler tones.

Do I chose:

UC inks with matte black and the Imageprint RIP?
or
Cone editions inks with the Studio Print RIP?

Any final comments or pushes one way or the other?

Thanks again,

Ellie
