Another option might be to do a little more wife training. Sneak her into some nearby setups that could blow HER away. You can always massage the user interface by setting up a universal remote with her usual activities easy to find.
That is another good suggestion. My wife did a 180 (maybe at least a 175) on the new home theater when she saw & heard the Axioms. The HG Cherry finished helped to be certain... With her, appearance is every bit as important as sound. When she heard them though, she was won over, and she is not a person who ever has gotten really excited about good sound in the past. (we replaced a 5.1 Bose system with Axioms, so it's fairly relevant experience, though we now have a dedicated room... so maybe it's not!)
