Ray,
I know the site recommends 2+ and 1- wire, but I believe that most people, including myself, have better sound with 1+ and 2-.
Of course, experimentation with the connections is so easy, try for yourself. The difference many people find is that the 2+, 1- configuration sounds too boomy and muddy. See which way you like it.
Give the wires at least 100 hours to break in. They get pretty good after about 50 hours, but need another 50 to come into focus.
I have used these as interconnects as well as speaker cables. They are good as interconnects, but not the best. Still, they might be the best for their price. In either application, what they do right is musical tone. I replaced some highly touted wires with these, even magnet wire as speaker cables. The WLM sounds musical.
Have fun, these sound very good. They are not ultimate, but they are very good and, most important, pleasing.
