According to Jeff Wisnia :
While I too wouldn't think that you could induce enough hum into speaker
leads to hear it, especially if you twisted the speaker leads about one
turn per foot, it is interesting to see that the Monster Cable Company
recommends keeping speaker leads away from power cables. See the
penultimate sentence in the second section on this page:

And as you just implied, "One successful test is worth a thousand expert
opinions."

If one relied on the "one successful test" theory, nobody'd buy Monster
Cable either ;-)
