I am one of those morons that ordered bi-wiring posts on my M80s. And on top of that... I'm actually using the feature!
For the money, I just wanted to have that option; I have used 4 monoblocks to power the speakers. Call it placebo, or whatever else you want, but I felt that this setup has more headroom and less congested sound at high levels.
I do listen to music occasionally very loud (~ 100-105 dB).
