@thiefoflight - not that broad a base for comparison but, perhaps most tellingly, I do use it in preference to the (at one time) well-regarded Stereovox XV-2 digital cable.
Compared to the XV-2, I think the D-750 is a little fuller bodied and more satisfying to listen to. The XV-2 has a leaner sound. Detail retrieval with both is very good. These differences are subtle, at least to my ears and with my gear.
Also have some lower cost Audioquest cable: VDM-3 and Dyson Audio Audioquest Solid Silver Digital Cable. D-750 detail retrieval seems better than the VDM-3. The Dyson seems dark toned and a little murky detail-wise (but it was cheap and worth a try!).
If you can find a D-750 with 30 day trial or used, it would be worth trying out.
