I thought I'd post an update to this thread I started. After being pretty sure I had adequately broken in the Curious USB cable, I decided to go back to my Wireworld Platinum Starlight 7 cable.
The Curious cable sounded more laid back and and I noticed better channel separation with the Starlight 7 cable. Didn't notice any greater "dimension" with the Curious. As far as I know, the better the channel separation, the better the soundstage.
Perhaps the Starlight 7 sounds better for the kind of music I listen to, which tends to be pop/funk, with punchy bass and drums. The high end of the Curious was kind of "sweet" sounding - extended and laid back, but the Starlight 7 seemed more real/natural sounding to me in general.
