That USB cables can make a big difference should no longer come as a surprise. Use the right cable and suddenly your digital system really starts to sing and at that point, you can’t imagine ever going back to the previous cables. Ok, the CAD USB I cable is not exactly cheap: 600 euro is admittedly not pocket change but in all fairness, this cable is not outrageously priced, given the amount of research going into it and considering that there is 4-fold filtering built-in. And if you need further perspective, just compare its price to the cost of high-end interlinks and power cables or certain other exotic audio accessories. But all that aside, it’s still the sound that matters and this cable offers a unique combination of technical accuracy and sonorous, full-bodied, natural and organic sound. Also, it works equally well in all the combinations that I tried. Highly recommended!
