Agree with audiotroy in that it is odd that she liked both KEF LS50 and Sonus Faber which are two totally different animals.
Maybe totally different sonically, but perhaps they were the two smallest speakers that she saw. ;^)
I recall my wife many years ago pushing for those cute little Bose Cube speakers. She thought they were adorably unobtrusive, unlike my "normal" full range speakers.
She envisioned them being very easy to "hide".
I never did buy the Bose Cubes, and eventually she just gave up trying to steer my audio purchases. I allow her to run her fashion sense in every other room in the house.
