Since budget has become an issue, I'd like to suggest a different course. Take a look at the Salk Songtowers.

Here is a review by a fellow Audioholic that owns a pair.

The beauty of these is that they should, by all the accounts I've seen, provide you with everything you are looking for a little over half the price of even the Dynaudio setup. Salk Sound is a different type of company than the usual speaker maker. Everything is custom, right down to the veneer and finish on the cabinet if you like. When you call, you generally speak to Jim Salk personally to answer your questions.
I have to admit, I have a fascination with Salk even though I've never heard them. By all accounts, sound quality is superb. Apparently, no Salk speaker that's ever been sent out for an in-home demo has ever been returned, and somewhere around 90% of all Salk speakers are still with their original owners. That seems quite a testimonial in my book.
As for budget, if they don't have the SongSurrounds ready yet, four Songtowers for front and surround and the SongCenter will only cost $3,700. But they are a 4 ohm speaker, so you would still want the XPA-5. All told with the Salk Song Series, XPA-5 and the Yamaha 663 as a pre/pro, maybe a HSU VTF2-MK3 subwoofer for theater use and a Blu-Ray player and you could walk out with an awe inspiring system for around $6K, plus the TV of your choice. It's a very budget friendly system that doesn't involve a lot of compromise, as far as I have seen from reading them but without actually hearing them.
At the very least, give Jim Salk a call at the number listed on the contacts page of his site and see what he can do for you.
