Tony,
Actually according to the folks at Monitor, the new S10's are the Silver 9i's big brother. The S6's would be more in line with the Silver 5i's or the Silver 7i's. I heard the 10's and they are an awesome speaker but I still like the Silver 9i's. I have been sitting here all day trying to decide if I'm going to ditch all my Axiom stuff and try and put together a total Monitor Audio system. My M3's blend rather well with the 9i's but there is something there now that is just not right. Have yet to put my finger on it but I will.

I don't buy into all the hype surrounding timbre matching but there may be a little something to it.

Anyway, I will get this figured out sooner or later. My biggest fear is if I go all Monitor again, I may have a hard time putting it all together as the Silver line is no more and the S line does sound a little different. Most reviews I have seen have people wanting the old ones vs the new ones.
