Curtis, I haven't had time - and won't have time - to A/B these before Sunday, so I do hope you're able to make it out here that day. Keg in the garage is still about half full, BTW.
Neverhappy, the top end sounds much different, but the rest of the speaker is similarly "neutral". Maybe it is my knowledge that the drivers on the S8s are also metal prejudicing my observations. And, again, I haven't A/B'd them yet.
Saturn, I think you are pretty accurate in what you said about the soundstage differences between the two, but in my house the S8s seem to produce a soundstage roughly even with speaker placement - some instruments slightly forward, some slightly recessed. The M60s, of course, throw everything out front.
I listened to some more of my favorite recordings (favorites on my M60s) to see what I might lose by keeping the S8s. The largest audible difference was noticed on some Bach harpsichord concertos. String basses and violins were more prominent, the harpsichords less so, the treble energy from the harpsichords greatly decreased. I'm not sure whether I like the speaker change for this recording or not, but other favorites still sound very good.
I did a quick calibration for HT and popped in Nemo. They blended very well. Lost some high frequency ambient effects, but seemed to gain background music - particularly violins.
