Power cord for 47 Labs digital front end?

I've got the 47 Labs Flatfish/Progression/Humpty front end, and although it sounds good, I think it should sound better. I'm currently using a Shunyata Anaconda VX on the humpty. The soundstage depth is great, excellent detail, however I think the treble region is amplified and forward in the soundstage, the bass is way in the back and muted, and the body is too lean. Aside from switching back to the stock power cord, any other suggestions?

FYI, the digital cable and interconnects are by Silversmith.
