Both CV-4 and Granite use PFC, while Granite uses them in a configuration called Double Quad-Helix winding using a mix of 16, 18, 19, and 21 gauge PSC, 8 conductors in 2 4- conductor helixes, the larger sizes used for bass in bi-wire setup. According to the literature, “PSC clearly outperforms previous AQ metals that cost over ten times as much”, this presumably meaning silver conductors. However, AudioQuest does still use silver for its most expensive cables.
The AudioQuest cables were terminated in a very interesting type of banana plug that is like a tubular spring and fits binding posts very snugly, making contact all along its length. They are not gold plated, but The CV-4/Granite hybrid cable was connected to the speakers through our Bryston speaker switchbox, which, while it may have its own colorations, allows instantaneous switching from our reference Kimber Select 3035/BiFocal tri-wire cables to the AudioQuest cables (in extensive comparisons with and without the box, I have never heard any degradation caused by this cable switching system, and have heard audible cable differences frequently when comparing cables through it. The box is fed from the 3B ST amplifier with less than a foot of Kimber 8TC).
