This article is verging on fraudulent and I have totally lost confidence in what is written by this magazine. My opinion now is that whatever they write where an opinion such as this is actually relevant has to be taken with a large pintch of salt. Shame on you What Hi-fi.
I urge all those claiming that they get better sound by swapping from one USB cable to another to make a dedicated effort to understand how computers works and familiarise themselves with the potential pitfalls of expectation bias. The data going through the cable is encoded in a digital form and then gets decoded by the DAC, which then converts that data back to an analogue signal, which can be ampliefied to drive speakers et c. The transfer of data from one digital component to another is bit for bit with no loss and if there is something wrong, it will not happen at all - it's all or nothing (data corruption).
Paying more for a good quality cable that will last longer may be acceptable, but £50 with claims of improved sound quality is ludicrous and as I say verging on fraudulent.
Performance of anologue cables such as speaker cables or inter-connection cables are indeed affected by their quality, of course, but USB cables simply are not.
I must admit that this wireworld cable has more influence on the sound of my audioset than any of the 6 speakercables (Van den Hul, audioquest, chord, ixos, wirewold) or 5 analogue interlinks (atlas, Van den Hul, monstercable, Ixos, Oehlbach) I own. This might be interesting information for those who still think there is no way usb cables can influence sound quality (like I did until a few weeks ago). It must be added that my dac is usb-powered so I have no idea if the influence would be the same if it would have a dedicated power supply. This does not mean though that I am completely happy with the results of this ultraviolet7 cable. The first connection I made was to my desktop-pc : the sound of my dac with this cable became horrible : voices an violins got much too thin, the bass was tiny, and the space around the instruments and voices was gone. As if I was listening to a very cheap audioset. The standard no-name usb-cable that I was using before, was superior to this wireworld cable ! Connected to my laptop with the same dac and the same music files, the sound became more precise and defined, the tonal quality of the instruments got better and music became more engaging. The music structure was in some cases completely different, as if I was listening to other music or other performing artists. I even did not recognize some of the pieces. Amazing, but of course it leaves me with questions. How can I know how the music really sounded when it was recorded if only a switch of one small cable makes such a difference ? Is it that this cable improves the electric flow and eliminates distortions or does it just filter critical frequencies ? However there is also music that keeps sounding worse with this cable : too thin and feeble, while the no-name usb cable performs much better with the same (uncompressed) files. Guess I still will have to do more research or go and buy the furutech cable to compare…. . So buyers be ware : this cable will not in all cases be an improvement.
I wanted to try a higher quality USB cable between the pc and the DAC to see if there was any improvement. Some people say that USB cables quality have no impact what so ever on sound quality as it's a digital signal and not analog.
Let me tell you something, that's rubbish!!!
I was using a standard USB cable, not a poor one but a good standard quality, two days ago I just swapped it for a Wireworld Ultraviolet USB.
Beside the fact that this new cable looks great, the sound quality improvement is just MASSIVE ! I obtained higher details, significant deeper bass and now the soundstage is just WOOW !!!

This cable proves that an included free cable is just what it is: cheap and only suited to check if the equipement works.
After installing the wireworld cable I noticed the soundstage got wider, high frequencies became softer (they were pretty sharp when using the cable that came with the dacmagic)and the lower frequencies are bigger and more defined now.
Just try it out, you'll like it too.
I bought that Wireworld Ultraviolet, not really believing a digital USB cable could really make a difference. Within 1 hour a trying it out, swapping it back a forward with a $3.50 generic USB cable, I decided to return the Wireworld Ultraviolet...and buy the more expensive Wireworld Starlight - there was that much of a difference!
or you could save £50 and use the "free" graphic equaliser that comes with the pc

A great amp with some notable musical skills, but it loses a star compared with its better-performing, better-specified rivals
Another admirable and attractive soundbar from LG, pipped to that fifth star by fierce competition
The large screen and punchy picture are highly attractive for this price, but you’ll have to forego the smart features and Full HD resolution
