Advice needed - Boston Acoustics setup

I am a novice audiophile (pardon the oxymoron), and I'd like some advice on this setup I'm considering for my home theatre system - assume it'll be used 50% for movies and 50% for music.

Floorstanding: Boston HS 450 pair
Centre: Boston HS 225
Surround: Boston HS 50 pair
Sub: Boston HPS10
Receiver/amp: Denon AVR 1610

I am getting this whole set up for around US$1100 - is it worth it? It's to be used in a 15ft X 20ft living room and I place a premium on clarity. Would love to get the Wharfedale Diamond 10 setup, as it is remarkably clear, but I'm afraid they're a bit out of my price range.

I've heard this setup, and it sounds good - just wondering Polk Audio's similar setup (Tsi400 pair, tsi 100 pair, cs10 and psw110) is better? It costs $300 extra - is it worth it? Also, should I plump for Denon 1910 to enable upscaling? I'll be watching quite a bit of TV on this, so might be worth it. Is th4e audio quality that much different between the 1610 and 1910?

Also, what's the general impression of these Bostons - are they respectable for an entry-mid level system? Thanks a ton guys.

Thanks Ron - it's just that I'm getting this whole system as a package in clearance, so it's actually cheaper for me to get these floorstanders than go with something like PSB Alpha B1 5.1, which sounds great, but since they are all small bookshelf speakers, they dont really compare with this setup. Plus, I'm not a huuuge fan of the PSBs in my price raneg - a bit too boomy.

Like I said, Wharfedale Diamond 10.5s are the best ones I've heard in this segment, but they're just a bit out of my budget.

Any thoughts on the 1610 receiver vs 1910? Or should I post that in the receiver forum? Thanks.

I saw some really good info on the 1610 v 1910 on the receiver forum, so that seems to be settled - have decided to stick with 1610 as I don't really need the extra bells and whistles.

Is getting the floorstanders AND a sub actually worse than getting bookshelf speakers and a sub? I mean, I can always turn the sub off if it becomes messy, can't I? Just wondering, coz I'm really getting these Bostons at a bargain, and they sound great. Only problem is the horrible Mist colour.

I've heard good things about Energy - unfortunately, they are well out of my price range where I am. I think I'll stick with the Bostons - thanks a lot for your help.

As for the colour, I'm lucky enough to have a partner whose response (when I pointed out that the colour would clash with the room was - "function before form. If you like them, buy them." Truly awesome reply.
