You never mentioned how much you're wanting or willing to spend.
The Caravelles are fantastic and go for around $5000.00. They have the piano gloss black finish that should wow your wife.
On the cheaper note, I have the old B&W Silver Signatures which were $8000.00 new that I would love to replace, but honestly haven't found anything that has made me want to take the hit selling them. There are three pair on Audiogon right now for around $3000.00-$4000.00. They are the granddaddy to the 805's. I've heard that neither the Nautilus nor the Signature 805's can touch them. They go down to around 35Hz and they do rock! They're also very nice looking.
The Reference 3A DiCapo's are really nice too, and only $2500.00. The one's with the piano gloss black finish at $2750.00 should wow your wife, the same as the Caravelle's.
