To expand and clarify on my earlier response to your query:
I own a Wireworld Starlight USB cable. I also have an Atlas Element USB cable, and a no brand audiophile USB cable that I bought for $120 from a specialist shop in Singapore 4 years ago (way before anyone in N America or Europe was marketing audio grade USB cables). In a nutshell, I hear no difference between any of these cables. For me, now, the value of the cable is the peace of mind it brings and the compatibility it offers in terms of how it looks and feels with the rest of my (expensive) kit. At the time of buying the Wireworld and Atlas USB cables I was willing to hear differences, but I can't.
Some context here: I have two laptops, each with ssd's for the C drive, and each with 1TB HDD's mounted in the CD drive bay. I use JRiver Media Center 18 on both. On one, my main system, I use JPlay. I can clearly make out the difference between JRiver with and without JPlay, and I prefer JPlay. I have a number of phono interconnects from manufacturers such as Wireworld, Atlas, Audioquest, Kimber and a few others. I hear the differences between these cables, but I struggle to determine a preference amongst my top 2 or 3, simply because for this type of music I prefer that cable, and for that type of music I prefer this cable - and I can't be bothered changing cables every 10 minutes. I use a Chord QuteHD DAC, a Luxman DAC and I have an Audio-GD DAC, and I have headphone amplifiers from Luxman, Violectric and Sugden. My preferred headphones are Sennheiser HD800's, though I have others too. I think of myself as a discerning listener; I look and listen for 'better'. I haven't found that 'better' in any USB cable, yet. I could be wrong, but you sought opinions on the Wireworld, and I offer you mine.
Now to stir the pot: Having willingly bought 2 or 3 USB cables in the hope they would offer something, now I just don't buy it that a signal in the digital domain can be changed significantly over a 1m length of cable. Bits in = bits out, or it doesn't work. (That's a full stop - '.') And that's the conclusion I've come to. I'm willing to be persuaded otherwise, but on this matter, for me, the onus of proof lies with the proponents of the case that USB cables do matter. That the bits can somehow be changed in that 1m cable such that "the trumpet is further back in the sound stage" or "cable x is much better for female vocals" is a load of nonsense that needs to be exposed for what it is. So now we are supposed to believe that you can buy pieces of copper with the ability to process bits that the best of DAC's can't manage? Stop and think about it for a moment - how can a cable rearrange bits such that they sound better in the manner that some people describe? Ah, you say, but USB cable x lets more bits through and that's what gives the better sound - so a $100 USB cable lets through more bits than a $50 USB cable? Now we're clutching at straws. Incredible, literally incredible.
I live in Perth, Western Australia. It is the antipode of N America. You cannot find a city further away from N America than Perth, WA. I download music regularly, and I would guess (but don't know) that much of the music I download comes from servers in N America. If a copper cable with an interface can manifest a change in a digital signal, I should be affected by that. Is the music I download different from that of someone who lives a lot closer to the server (lots and lots of cable and lots and lots of cable/device interfaces to get to Perth from N America)? If so, then how much different? If on the other hand, the bits I have stored on my HDD that were downloaded from N America are the same as the bits you have for that same piece of music, then nothing has changed in transmission. How then does a 1m USB cable alter things?
Much more likely is the role of confirmation bias that dominates much of HiFi (I'm subject to it myself - I've spent nearly $300 on USB cables, and I declare a preference for JPlay!). My advice is, buy the cable that makes you feel good. If you can afford $100, and if it doesn't stop food being on the table, then buy it. You'll feel better for it. Your system may even sound better, and that's what you're after.
