I pulled the trigger on some Monitor Audio S8s in the Rosemah finish
Very nice and congrats. All my MA stuff is in Rosemah also. Excellent fit and finish. I have never done the MA8's against the M60's but I did get the chance to do the MA10's against the M80's. I don't want to compare them as I don't think that would be fair as they are two vastly different speakers. At the end of the day however, I would have taken the MA10's home every time vs. the M80's as they were more to my liking. I also prefer the MA8's over my M50's but again, I'm not sure we are in all honesty talking apples to apples!
As I still have yet to hear the M60's, I can't say what to expect from your comparison. If I was to guess I would think that the MA's will have better all around bass and slightly more laid back midrange and perhaps a little bit more forgiving on the high side. I have heard the MA8's on a number of occasions and I personally think they are a fantastic speaker.
Last week I spent a few hours with a set of Monitor Audio GR60's.............now you want to talk about a speaker, dam those MA60's are nice set of speakers. If I could wing it financially I would be all over them. I have heard nothing like them.
