That Uptone USPCB shows you just how colored other (Curious, cheapo and AQ I forget which) cables sound.
No going back once you have tried, unless your system prefers the rounded, smoothed sound that a conventional cable gives you, which is totally possible. But information-robbing.

I played around with USB cables quite a bit a few years ago, including some on the more expensive side of things and also those using scientific USB standards as their basis. Curious, Dana Cable, JMaxwell, some DIY using Zenwave’s tip end silver/gold wire, and the most recent DB Audio cable. I have gone back and retested this over time as well, as my system has evolved and improved. Even the very best of these USB cables pale in comparison to the clarity that the Uptone USPCB provides.
USB cables are bottlenecks, pure and simple. If I were ever to need to move on from my Sonore Ultrarendu or something with similar form factor that can connect via USPCB right into the DAC, I would absolutely look for a DAC with properly designed Ethernet input before ever buying a music server that requires a USB cable to my DAC. The issue is that important in my mind. You can certainly get good sound with a USB cable, but it’s going to be a big bottleneck to any system’s true potential.
