It seems to me there have been quite a few comparisons in the past. Chess posted his thoughts on them along with some other speakers. I believe BigWill replaced his M60s with S8s.

I haven't heard the M60s, but I did listen to the Monitor Silver Series and I preferred the S6 over the other models. Thats just me, though, but my ears liked those best.
