Crystal Archive II is perfectly capable of rather brilliant saturated prints, but you might need to use a more saturated film to begin with, like Ektar, to get there. It's also dependent on the degree of enlargement. Anything more than 8X will begin to get a bit washed out. Then there is the issue of whether or not the dichroic coatings on your colorhead filters are still in good shape or not. There is a way to moderately increase contrast using what is called contrast increase masking, but that's a specialized skill. There are also more saturated versions of Crystal Archive media, but they only come in large roll fashion.
