I've heard a variety of Wilson speakers including the XVX, Alexx 5s, SashaX and so on.
I have Sonus faber (my third set) so I have my preferences. The best combination of sound for me was ARC with Sasha X (versus D'Agostino with XYX, Alexx 5 with Martin Logan or Jeff Roland).
So it's possible and it may only be to the ears of the beholder...
