BY APPLYING THE QSeries architectures developed for its analogue cables, KLEI aims to bring similar benefits to its digital cables. The cable’s architecture is designed to maintain a zero voltage and low-noise earth state, claimed to enhance the electron flow in the signal conductor. The aim of the design is to produce a cable that protects the signal from surges and RFI, capacitive and inductive effects, as well as static charges, in order to facilitate a smooth uninterrupted signal flow from one component to another. As a result, the components are effectively isolated, allowing them to perform their individual task without interference.
The cable is fitted with a USB Type-A (flat) connector at one end and a Type-B (square) at the other, making it suitable for connecting a PC with, say, a USB DAC. I use it to connect a Windows PC to an Alpha Design Labs GT40a (HFC 399), acting as a DAC for playing files stored on a PC through my hi-fi.
Get in position… after running the cable in, I put it through its paces with some jazz and Cecile McLorin Salvant singing Mad About The Boy. This relaxed piece is very involving and the piano, double bass, and drums are superbly clear. The soundstage is very well laid out in front of me and McLorin, together with each instrument in the ensemble, has her own clearly defined position. In particular, the piano is very believable, especially in the Bach-like solo section of the track. Elinor Frey on the cello and David Fung on the piano playing De Falla’s Nana is extremely captivating. The position of both instruments is well defined with the cello very much in front and to the right of the piano.
It may be costly for a USB cable, but it provides a solid connection for digital audio components and its performance is hard to fault… Neville Roberts, HiFi Choice 🙂
At the moment I am using a short Curious cable from an ISO Regen into my Direct Stream. Generally the Curious has the edge on other USB cables I have tried and have mentioned it before in various threads. Cable and connector inventor/designer who I know, Keith Louis of KLE Innovations, borrowed my Mac Book for consistency, to use and test with his new USB cable design.
He bought the Mac back along with his KLEI™QFLOW7 USB cable and, well I was stonkered – KL’s KLEI QFLOW7 USB cable was really up there. Compared to the Curious I thought it more analogue like and the sound stage widened with greater depth. It was more organic. Characteristics of texture and organic type sound implies better harmonic resolution, so maybe that’s what KLEI™QFLOW7 USB cable was delivering.
What I can say for sure is that the KLEI™QFLOW7 USB cable is one fine USB cable. Well worth giving it a try and I got one to go with my Curious… BH 🙂 🙂 🙂 🙂
