ok, so I finally make a decision on the Focus for the mains and the cc270 ctr channel which is perfectly matched w/the Focus. then it hits me ...I can,("For a few dollars more") upgrade to the mini monitors. My salesman is reccommending the cc370. Is this just a ploy to get me to spend a few more bucks? Or is the mini and the 370 the closest possible match? will I hear the difference if I went with the 270, and the minis?
