If you can stretch your budget slightly, go for the Kef q series(the old range), I use to have the q55.2 fronts and q55 for rears, total cost a year ago for those four was £400, I only had the coda centre though.
They sounded brilliant, but you will have to factor in a decent sub in the future as well, but that can come later.
Some people still reckon they are better than the new series for sound, I do like the look of the new ones, I demoed them and preferred the sound of my Q55.2s to the new ones.
In any case you want to demo them, that way you can see if you like the sound or not.
Demo Demo is the only way to go with speakers, have a shortlist of a few ranges so you can compare for yourself, then you know you've made the right decision.
There are lots of other choices in that price range.
Good luck and enjoy whatever you get.
