The spousal unit and I have just completed our first speaker search as a couple. My spouse, a musician, initially wanted stand mounts (Genelec, B&W). Based on past experience, I wanted floor standers (as close to full range as we could get for our budget). After considerable auditioning, we decided on a pair of GoldenEar Triton 3+. You could say that they have both "detail and warmth". They also had attributes we both considered important: large soundstage, generous sweet spot, transparency, coherence, dynamics. (Much to our surprise, neither of us liked the LS50s.)
I am with audiotroy - what specifically did your wife like abut the Sonus Fabers and LS50s. (The house sound of these two brands sound nothing alike to me.) What kind of music do you both listen to? What's your budget? I assume you both brought along some of your favorite music to the auditions.
Just for the record, I am the wife, and I am the audiophile. So now, jnovak, you've heard of a wife who cares more about how a speaker sounds than how it looks. ;-)
