400xi is very synergistic with Vienna Acoustics Mozart Grand, or other Vienna Acoustics speakers for that matter. It is one of those combinations 'that work'.
However, if you want to have best of both worlds (400xi and Plinius) I would suggest geting the new Krell S300i.
Elberoth2 -> I was thinking about the new S300i, although i dont like the design and build quality comparing to 400xi. Did you have a chance to audition one or compare to 400xi? I think there is at least one member here on audiogon that changed his 400xi for s300i and came back to the 400 after all.
