Best SS 200 wpc amps

I need a high current power amp for my B&W speakers. My system is Sony SCD-777ES into BAT VK-30SE to B&W 803 Matrix Series II speakers. My current amp is a SS Kinergetics Class A 75 wpc (rated at 130 wpc Stereophile). I want to upgrade to something reasonable and probably look for something used. I want something that is fast, dymanic, handles macro/micro swings, sweet mids, airy hi's and controlled bass. The B&Ws seem to love high currrent amps with some watts.

My list so far looks like Krell FPB-200, Sim Audio W-5, Rowland, Pass x-250, McCormack DNA -225 & maybe Edge. What do you suggest?

Thanks.
