Ha, Wireworld Starlight 7 USB owner here as well. I like the brand, especially since they have a wide range which means some models @ real-world pricing in addition to the esoteric stuff. Audioquest does this too. I'm using Wireworld interconnects and power cables as well.
To be honest, I'm actually using the USB3 cable that came with my iDAC2. (Horrors !) Nice and short and fits well. It seems well made too. In general I see cables as refinements and haven't gone too far (IMO) with it. Been trying to improve the essentials.
I've been using a Mac Mini as digital source for 11 years now. My first couple DACs either didn't have USB or had a poor USB implementation so those were always Toslink or S/PDIF coax connection. So its only been somewhat recently that I've been looking at things USB.
It really wasn't all that long ago that I became interested in seeing about options for this interface. A Wyred4Sound Recovery was a first step which made me see that there are options to improve fidelity, particularly when using a bus powered DAC with a general purpose computer.
The rabbit hole continues in the near future with an Allo Nirvana power supply and a split power/data cable similar to the Pangea shown in an earlier post. Our resident
