LOL. I think he missed your sarcasm. But there's plenty of people in the audiophile community who believe that their ears are among the one in thousands that can perceive differences between two identical sounds. That's psychoacoustics for you. Engineering and science is another matter.
I'll take a pair of unshielded 14-gauge oxygen-free copper cables for my speaker wire any day over a bi-wired (4 strands) of the same 14-gauge oxygen-free copper cable (2 strands per terminal) for any run under 40 feet. What you gain in decreased resistance you would probably lose in increased capacitance, but the differences would not be audible. I'm a fan of the Blue Jeans Cable keep-it-simple design.
But seriously. You can buy 100 feet of 12-gauge Beldon 5000UP paired speaker wire for 80 dollars plus shipping. If you truly believe that 12-gauge is better than 14-gauge or 16-gauge for a 10 or 20 foot run of speaker wire (the difference is NOT audible), you can save yourself a lot of money by just running the wire and using bare copper ends for your termination. A good paired 12-gauge speaker cable should run you less than a dollar per foot. If your speaker wires are only 10 feet long, you don't need anything more than 16-gauge copper wire unless you are driving massive current into a 2-ohm speaker. Don't pay more.
