From what I know, the M60s and the MA Silver 6s are head and shoulders above the others. The only ones I have heard of your other list were the Monitor 7s and 9s. The 7s were a bit anemic compared to the 9s, and M22s (the M60's little siblings) blow the 9s out of the water in terms of sound quality, clarity, soundstage, and overall wow factor. The only place where the 9s did better was bass, but since yo'ure looking at the 60s, that's not really a concern.
The MA Silvers are highly regarded; but I've not heard any of their line.
