OP both are good Kef's have their house sound and the Sonus have their house sound.
Kef's are clean detailed with a very netural midrange, great dynamics and they thow a huge well focused soundstage the Ref 1 have unbeliveable deep bass for a stand mount.
Sonus Faber's warmer in the treble a slightly more colored warmer midrange, good dynamics and their stand mounts do not have the deep bass response of the Kef's if you want a warmer more full bodied sound with a less defined soundstage, the Sonus are fantastic.
