I have spoken with an Audioquest customer support over the phone the other day and he told me that the lower end models are indeed made in China but their higher and series or models are manufactured in house in California. For example, the AQ Blizzard power cable and lower are made in China but anything above the Blizzard line are made in California. The same applies to their speaker cable lines, interconnects, and other cables.
in regards to Cardas cables all of their cable lines are made in the USA. I currently own the Cardas Clear Reflection speaker cables and 2 pairs of Clear Reflection XLR balanced interconnects in my setup and I can tell you that they are all made in Oregon, USA. The dealer had them shipped directly from their factory in Oregon to my house here in Seattle. And on the box and on the cables themselves it says made in USA. I also used to own a pair of lower end Cardas Clear Cygnus interconnects, which is a step down below the Clear Reflection line, and they are also made in USA because it says on the cable itself and on the box.
