I think, as the unofficial, self-proclaimed, fearless leader of the M60's posse......it's time I chimed in here.
You all, are wrong. The term "bi-amping" when used in reference to the M80's, simply means: two amplifiers. One amp for normal use, and the other amp wired in, so when the first amp overheats, or shuts down.....with the flip of an A-B type switch, the second amp takes over, so no listening time is lost. whistle

M60ti's, M60v2's, and M60v3's, all Rule!
