No one actually knows how to lculate what speaker cable they need

Ok, you caught me, geoff and I are in the cable business. Our company has developed a formula based on common sense and practical application. Wire that can actually bend and not possibly rip the connectors out of the gear. Wire that would complement the looks of our listening environment. Wire that 99.9% of the world's audio enthusiasts use today and will in the future. Wire that sounds great and won't break the budget. Wire that one doesn't have to buy tools to build. Wire made by people that don't demand that we know all and if you disagree, you are a liar. Wire that will actually stay in the system for more than a month or so. Wire that doesn't claim "a scientific fact that some guys went the extra mile to try it and returned to share their impression". Wire that helps one dial in a system that is emotionally satisfying, not so called " scientifically" correct. Isn't that, after all, why we build these systems? 

This should be interesting, the saga continues ...
