$6-8k Speaker Options

[Intamin]

So after much debate, research, and decision making, I've settled on a price point of 6-8k for a pair of towers. I'll be saving my money up over the course of this next year or half year (I'm a college student with no expenses at all, lucky me!). Anyways, I've decided on this price range as it seems it's generally the top of line area for most speaker brands, without going into the 5 figure range. So I'm trying to weigh my options and figure out which brands I should be listening to in the upcoming months so that way I can plan out the trips (if needed) and get it all lined up. I want these speakers to last me at least 10-15 years so I can enjoy my setup hopefully without getting the upgrade bug. Here's my current list of options:

Paradigm Signature S8's
B&W 803D's (right at 8k a pair I believe, if more, not really a problem)
Revel F52's
Dali (not sure which ones fall in that price range)
Monitor Audio PL300 (I have no idea what these run, but the GS series is 3k, so I would figure that the PL's would be in the range).

So are there any other big name brands I'm missing that need to be listened to? Thanks all, and any advice or insight to the speakers if you have heard them yourself would be great.

Finally, I'm located in Indianapolis, so if you happen to know of dealers in my area (I've done the dealer locater bit on the websites) that you would recommend that would also be preferable. Let the quest begin!
