Actually Kimber cable doesn't make the best speaker wire it's just junkie ofc wire, the best wire for sound is OCC single crystal wire and that's been proven for over 40 years now
Comparing Speaker Cables
I have accumulated several pairs of speaker cables that I have never tried to do careful A/B comparisons of because the time it takes to swap them is longer than my audio memory. But my speakers are bi-wired and it occurred to me that I could hook two different cables up and then only swap them at the amp which would be much faster. Is there any sonic downside to having a pair of unconnected cables hanging off one of the sets of inputs while the second set is connected to the amp?
