I agree with the above. Ditch the Bose and never look back. For a budget of $5000-$7000, you can really do some damage...hell, you could probably do some damage for less if you just read some of the posts in these forums. Figure out what pieces you want, then look around the forums for reviews/suggestions on those pieces and then make your purchases...and of course demo stuff before you actually pull the trigger.
Wow, I'd love to see what I could do with $5K-$7K. Lucky.
