I think that's the main point here - pretentiousness. I've heard so many different Bose systems in many different environments, and have never been impressed with them. It's easy to jump on the bandwagon and bash Bose (like Monster), but it's always refreshing when someone attempts to go in with an honest objective approach like the OP and see if the product lives up to its high price tag. In just about every case, it simply doesn't.
Are they OK? Sure, they get the job done every bit as much as a Monster HDMI cable will get the signal from your source to your TV, but is it really worth that much cash when it just sounds OK, or
just does the job? I find it amusing still, that Bose is so secretive about their specifications and frequency response numbers, knowing full well that there are numerous audiophiles and 'holics around the world who know what those numbers are telling them. Subjective listening aside, the numbers can still (and do) tell a lot about the performance characteristics of that product, and Bose is understandably reluctant to share this with the world.
Simply put - Bose is a rich boy's toy, someone who only wants to spend that much money because he/she can and doesn't really give a crap about the actual listening environment as much as (we) probably do overall. It's an emblem, an icon, a status symbol, and nothing more.
