I don't know if there are subtle gain differences at the same volume setting between optical and USB affecting my assessment.
I don't know if I just have an insane amount of interference with my LAN network having impact on my USB.
I don't know if the technology in optical has made a sneaky and significant advancement.
But I prefer my MbP TOS out with SN7 to Hugo, over my: Synergistic Research/Nordost Heimdall2/Cardas Clear USB to AP2 + PP to Hugo. It sounds more dynamic, clean, open, and lively - with less distortion.
I don't know if it's this optical cable specifically. I don't know how it compares to the Sysconcept. But the SN7 is better than the other 3 I have (AQ Cinnamon, Monster, Chord stock). And it's built so extremely well.

I have been using USB for a long time on my Mytek and CAPS. Today got an itch to try the SPDIF of my Gigabyte motherboard. Boy was I surprised!
Its hard to admit but I like the using the Toslink more. The sound is more fuller, more organic and the digital artifacts seems to be gone.
Am I hearing it right?
Probably. I use Toslink. I have an expensive USB cable sat around doing nothing these days. I have used my ears, not science, to judge. But I would qualify that this is what I hear in my system only. I can't comment on others.
But I guess the galvanic isolation is an aspect. The criticism of the Toslink Tx/Rx being very jittery is perhaps a tad overblown, given that jitter correction/rejection is now built into some DAC's.
AQ 的 Diamond 石英光纖線最少 20K,Wireworld 的 Supernova 7 為 8K 起跳,QED 的就 6.5K 左右:

評價好像不錯?
