That's very close to the wall so you will get accentuated and bloated bass from any speaker I've heard. Based on my experience (and I hope there is some magic answer out there from someone with exactly the right experience), I'd suggest smaller monitors if you are going to be that close to a wall: There is less bass to bloat. A separate subwoofer or two can be placed elsewhere -- careful about the matching though, it can be tough. By the way, if you are that close to the wall, wouldn't something be between the speakers? If so, that will probably affect your soundstage (e.g., if a TV or cabinet protrudes further than the speakers do from the wall).
You may want to also check into some beautifully finished speakers that you can insert more into the rather large room that you have. A gorgeous set of speakers could go a long way to offset partner acceptance issues. It might, in fact, be better to have an A-/B+ speaker out where it can "breathe" than to have an A+ speaker snug against the wall. There are plenty of threads here about good speakers in your price range. Look at pictures of those and decide which might best meet your wife's approval. I don't know your furnishings or style so can't make any suggestions. You may wish to share that so others can jump in with ideas.
