I had their original interconnects and speaker cables (Cactus and Desert, I believe), and still use their interconnect for my tuner. I like it, it's quite neutral, maybe leaning a little to the rich and sweet rather than bright and ruthlessly revealing. I replaced some old Siltech 4-56 interconnects with it, preferring the Sonoran over the brighter, admittedly early generation of the Siltech, and replaced Dunlavy speaker cable with it, I felt they were close but that the Sonoran slightly bettered it in transparency and dimensionality. The interconnects have a ground wire, actually a handy thing perhaps in some applications. I don't know if this cable is still made; it originally was made by a gentleman in Tucson, Arizona, who may have moved to North Carolina. The only weak cable of theirs I owned was their digital cable, which I found ordinary, not outstanding as the rest of the cables. I think there were some later versions of the cable which were less expensive. Overall, I think they're a very good value, particularly at their used prices.
