I was just about to post a comment that someone else had suggested to me the Sony STR DG910.
By the sounds of it Davey23 you thoroughly recommend it?
How do you have your PS3 connected with the DG910?
Is it just connected via HDMI or do you need an optical connection for the audio? (Bit of a noob)
With regards what speakers I have, they're an old set of mission ones (not sure what model but quite old) I managed to get them off my Dad when he upgraded his system some time ago. I didn't really intend on replacing them.
