...IMHO....

Actually, hold on a sec; you didn't mention that you had a sub, sorry that I missed that first time around. You'll want a sub with for HT if you go for the 685s.
If you *can* move up to the 683's, I'd recommend it. Mine cost me 800 quid plus another 300 quid for the center and they were well worth the expense. Of course, they're a lot bigger than both the 684 or 683.
And one other thing to consider. 685+speaker stands is almost the price of a pair of 684s.
I guess the question in all of this really is, do you have future budget for expansion? My order of preference would be:
1. 683+htm62
2. 685+asw610+htm62
3. 684+htm62
But again, that's just all my opinion. YMMV.
