I'm looking for nearfields in the less-than-$600 range for my small 16' x 8' x 9' room. So far the candidates are Yamaha MSP5, Behringer Truth 2031, Yorkville YSM1P, and Yorkville YSM1 passive with my Hafler P3000 amp. What's the best for my budget? Can I expect a decent performance in this price range or should I save up for Genelecs or some other high end stuff? Thanks for any inputs! Michael L.
