Krell fpb-200 advice

I 'am about to buy a Krell fpb-200 (not c or cx) to get the best possible bass, dynamics, speed, accuracy, in this budget and in this frequency range, from my active bi-amp diy speakers (15 woofers/97db eff.) under 300Hz. Considering the very good efficiency of these woofers i think that 200w is sufficient comparing to the higher power fpb, isn't it?
I thought it was one of the best, that i avoid its supposed weaknesses as i will use it in this particular active config. and as i use a CJ mv75 for smoothness, presence etc.. above 300hz (midrange/highs soon to be replace by an ARC vt100/kt88) ; but i read here and there very mixed opinions, some says it's muddy, dull, that soundstage lacks depth and focus etc...
others that is simply musical with big slam, what i'am after in fact! Where's the Truth?
As I couldn't listen to it in my own system before I buy, I would very much appreciate your advices!
Any input is welcome, thanks!
