about to fork out for a onkyo 606 and im starting to think of suitable speaker set to go with it - either 5.1 or 7.1.

I dont have golden ears and mainly im just interested in getting out the popcorn laxing back and watching movies, hummm and the F1 (although chances of turning the sound up past a whisper at 1am during the season are small unless i want a divorce)

Does anyone have any recommendations for some decent $midrange speaker setups - or some thumbs up for systems you already have?

I quite like the wharfdale diamond 9's although starting to get to the pricey end of what i'd consider spending. In saying that i'd rather spend the money and be happy than cheap out and have to look at something crappy for the next 5 years.

any helpful suggestions appreciated.
