WireWorld Ultraviolet USB Cable:
WireWorld has also been around for a number of years, and makes cables for every type of audio connection as well. They have a unique take on cables in that virtually every cable in their line is flat design. They have also developed a unique geometry called DNA Helix that they claim rejects noise and enhances the electrical properties of a given cable.
The WireWorld Ultraviolet is the first in a line of multiple USB cables, and it features proprietary technology specific to WireWorld. Pricing starts at $44 for a half meter. According to WireWorld: “The Symmetricon design (used in Wireworld Starlight Ultraviolet USB Audio cables) utilizes four signal conductors, effectively doubling the area where electromagnetic energy is channeled efficiently through the cable. Another special feature of Wireworld USB Audio cables is a shielded power conductor that is isolated from the signal conductors for cleaner power and improved sound quality.”
An important design feature that distinguishes their USB cables, as they note, is the separation of the data conductors and the 5 volt power conductor that is part of every USB cable, which are usually grouped together. The cable is very well made, and is finished in an attractive purple color, with high quality connectors. Because of the flat construction, the Ultraviolet was not quite as easy to maneuver as the Audioquest Forest. But this has been my experience with all flat cables, regardless of application. I used the same setup as described above, and I heard virtually the same set of performance improvements over the stock USB cable.
The lower frequencies had more weight and definition, which cleaned up smearing and overhang into the other frequencies that were occurring with the stock USB. Of course, deficiencies in generic USB cables are often only apparent after installing aftermarket cables. The Ultraviolet was clean, clear, and defined. As with the Audioquest, the difference over the stock cable was subtle, but easy to hear without even having to listen critically. While more expensive that the Forest, the theoretical benefits of a separate power lead and its increased manufacturing costs make this cable fairly priced.
Having both the Audioquest Forest and WireWorld Ultraviolet USB cables in my system for an extended period of time convinced me they are both cost effective, nice upgrades over stock USB cables for high end computer audio set ups. In my opinion, if you are listening to CD quality lossless files or HD downloads, it would be silly to use a generic USB cable when the cost of a good aftermarket cable is fairly reasonable.
Both the Audioquest Forest and WireWorld Ultraviolet USB cables are fine products from companies with long pedigrees. I have added both cables to my system. I do wonder how the USB cables higher up in the line compare, but my budget would not allow me to go much higher for this application. Both cables are highly recommended.
