I echo Semi's thoughts on the Plinius. It depends on system matching as always. Plinius sound great with Dynaudios but can be too warm and shut-in with Sonus Fabers. I have used the SA100Mk3 to drive lower range Sonus Fabers and the result is not good with undefined bass, muddled midrange and rolled-off highs. The newer range Memento may not be as warm and colored but still I would advise caution against the use of Plinius amps with Sonus Faber speakers.
Pathos Logos is a pretty engaging hybrid amp. One of my friends owned the amp for a while and eventually sold it off as it didn't give him the PRaT and excitement he was looking for. For what you seek you might want to look at Naims. There are quite a few Sonus Faber users who used Naim amps on the speakers with excellent results. A 282/250 might be worthy of consideration.
