@Mesch, could you talk a bit about how the Columbia improved you music over the KC. I demoed a new pair of Columbia a couple of weeks ago. I had it my system for 7 days so it had settled in and I got a decent handle on its sound. I did like it. It was detailed, quiet dynamic and smooth. In my system I need a bit more fullness/weight in the mids.
I'm trying to figure out if I should try the Yukon just below the Columbia and save some cash or try the Colorados. Thanks for any thoughts.
