How much better is the Krell 400xi compared to the

I have a 400xi (with probably less than 200 hrs on it). I've also got a Conrad-Johnson PF2 preamp and Hafler 9500 and Odyssey Stratos power amps. Of the three combos (400xi, PF2/9500, PF2/Stratos), the 400xi sounds sweetest on top; the PF2/Stratos has the largest soundstage, and the PF2/9500 images best. Soundstage size is about the same between the PF2/9500 and 400xi (perhaps slightly smaller for the 400xi). The 400xi and PF2/Stratos have slightly smoother midbass than the PF2/9500.
