I recall buying about 5 figures worth of 16ga 99.99 silver wire, custom printed heatshrink and connectors and then at about 42 days of 24/7, but maybe 5 hours of normal listening levels a day the speaker wire started to break windows from two blocks away, sinking ships and scraping the wall paper off the walls in the upper midrange....I then spent six months figuring out how to configure and break the stuff in so it wouldn't do this as that sort of investment could not be regained selling the stuff off as clothes line....Without getting into specifics the bottom line is that silver needs to be put into a situation wherein it is run hard and put away wet well past what it will ever see on a musical peak or it will be bright on those peaks....
