Just my 2 cents.
I pretty much use Cardas cabling throughout my system and have tried most iterations of their cables.
The current Clear range will not give you the midrange bump that the older Golden range does. Clear Reflection does somewhat but is still different. The highs are smoother and more extended though. Golden Reference could sound a bit hard in the highs with some material.
I did not like Clear and preferred Clear Beyond and Clear Reflection interconnects. I used to like Golden Cross over Golden Reference so that gives you some indication of my preferences.
I tried Clear Digital SPDIF and Clear HS USB. Both give you the Cardas midrange magic but again not the midrange bump and fullness of the older range like Lightning 15 or even Neutral Reference digital. I found Clear Digital to have lots of air and space between instruments but was “lean”(er) sounding in my system although that’s all relative. Others have found it to be warm sounding. So if you want a fuller and warmer sound and want to stay with Cardas, go with the older Lightning 15 or Neutral Reference. If you can find them, they sell for very reasonable $.
Overall, I prefer Aural Symphonics for digital. There is a certain musicality and rightness about them. If you can find an older Digital Statement or Echelon Digital, I would recommend it over the Cardas. Unfortunately, they are rarely available used.
For a lesser known brand more popular for their USB cables, you can try Phasure Audio Blaxius. It is full sounding and the bass has an astounding physical presence. Images are fully fleshed out. But the mids are not as sweet as the Cardas Clear SPDIF.
You can also try Transparent Reference or Reference XL but these go for more $.
