For me, having lived and worked in Italy some years ago, Sonus Faber has a certain romantic quality and hence, great appeal. Call me a bit of an Italophile (is that even a word?) but Italians sure know how to design and craft some gorgeous things. A side benefit is that SF speakers have excellent resale value, which is one of your concerns.
I owned a pair of highly-regarded floorstanding speakers for many years, and although they sounded pretty good or better, depending on the room, I could never get over how "homely" they looked. :) I finally sold them for a fraction of what I paid for them, even after I spent a lot to have them upgraded. My next speakers were Sonus Faber Liutos. A weight had been lifted. :)
