In my case the Sonus Fabers were replacing some older B&W speakers that looked like boxed robots... She loved the look of the Oly's so it was a non issue for us... and she loves the sound too.. Female vocals, live jazz and acoustic recordings are amazingly enjoyable on the Sonus Oly's.. Older rock can also be great depending on the recording qualities.. My old Buffalo Springfield album and Neil Young come through wonderfully... I am not a high db listener but the 4 ohm Oly's crank it out if I want to with an old 100 WPC ARC solid state amp.
My wife is a visually oriented person as are many of women that I worked with in my A/V sales years... I suspect as mentioned above that your wife might be interested in the visual qualities of the choices just as much as the auditory preferences.... Regardless, if you search around enough you will find something you both love.
