OP,
You have no way to audition?. I would think about that. These are, I think $7K speakers. It would be worth 10% of that to experience them? I am sure you can drive or fly to a city with B&W on display. Make it a weekend trip for the fun of your pursuit. Nothing wrong with confirming your love of the sound of these speakers. B&W are great rock speakers with substantial bass and a pretty hot high end. Set up auditions in advance… with a couple competitive speakers. Take your wife with you… take her out for dinner and a show. Make it fun for both of you.
The differences folks here are talking about are pretty small nuances unless you are very familiar with the sound of B&W.
