Well, thank you all for your help...now I've gone and done it!
I just bought a pair of black M60v3's from the factory outlet/auction page for the minimum...$889.00. No other bidders and I wasn't spiked! (if that's even possible there)
They still have the full 5 year warranty and the 30 day return policy.
The M60's were what I was leaning towards from the start but got "off track" with all the glowing reports on the M80's.
These are essentially the same as my M2's with woofers and a larger cabinet so I am hoping they sound similar in the mids and highs.
My 3808 has Audyssey XT so I am hoping that will flatten out the 2dB broad mid dip and the broad bass peak that I see in the NRC graph.
