What gauge do I currently have?
My cables are Audioquest Comet biwire
Audioquest does not publish specs regarding their cables gauge or electrical behavior, for some reason. I'm guessing here, but I doubt they offer large gauge speaker cable for their low-end or mid-range lines. Like many cable companies, they save the large gauge wires for the big boy$$$$.
The suggested large gauge cables are an affordable way to bring low resistance signal transfer from your integrated amp to your speakers. Given the same cable design, a larger wire gauge should yield lower resistance values.
