X-Fi Titanium vs X-Fi Forte (For optical)

Hello everybody. Right now I'm considering an audio system upgrade. What I'm trying to figure  out is: is there any point in upgrading to the Forte if my intention is to plug it into a little dot dac I? I realize that by moving to the forte I gain the extra digital output, but that may result in the same issue I experience now, a ground loop (since there is a ground channel).

It doesn't help. Only thing that fixes it is a ground lift. What I'm curious about is just whether or not the Forte has a better implementation of the optical output or not. So you're saying it does?

I'm curious if anybody has listened between the two and heard a difference. I have no doubt that the analog output is better, but would like to know if there's any difference that can be heard between the two using optical output. I appreciate your input robscix since I know you've reviewed some of this gear. You wouldn't by chance have an optical dac and both cards handy, would you?
