Am about to take the plunge into home cinema but don't know whether to go for a 5.1 package or just the 2 fronts and a centre speaker? My living room is not ideally shaped for rear speakers (TV sits in the corner of the room) so these would need to be stand mounted and be moveable so they can live in the corner of the room when not in use. I'm thinking that I may just be better off going for a decent set of fronts and centre. How much would I be missing by losing the sub and the rears? I have a budget of about £300 - £400 for the amp and speakers so any advice appreciated.
