With that budget you 've got some great options depending on room size and layout, i would opt for the B and W range something like the 685 and Onkyo 875 for £1800 you can also mix and match from the different ranges 863, 864, or even just buy the centre, fronts and sub and add some MT30 satellites for the rears and wall mount them. Other options Tannoy F4 Customs and F1 customs for £800 F4 being floorstanders. I think if you've got the room go for the traditional packages, if not than the Kef 3005se or the B and W MT-30 would be your best bet
