In another thread, The Pro recommended the yamaha MS202II powered monitors. As I searched Yamahas website, I noticed they now manufacture 2 powered speakers, the MS 300 and 400. They weren't listed a few months ago. Along the Mackie/EV/EON lines. has anyone test driven these beasts? they aren't listed with musicians friend or other internet music stores yet. Looking for input and reviews if anyone knows. Thanks Brian
