Tyler did some great profiles for my 8300 and my HP recently. We compared the gamut of his 9900, my 8300, and my HP Z3100. My HP held up quite well against the Canon with matte media. The Canon has a slight edge in some of the darker coolish hues compared to the 9900 and the HP Z. However, overall the 9900's gamut is supreme in most of the obvious hues when viewed in Color Think. So like he just said if you need the absolute best gamut for proofing services, ad work, and such and moving close to what we had with dyes, the 9900 HDR inks are out front. We still need to see how the Canon inks pan out in long term fade tests though. In that regard it appears to have a jump on the HDR inks, but no where close to what the HP Vivera inks show.
