Surround sound advice needed
Was wondering if anyone could suggest how I can upgrade/better my current living room 'surround' sound set-up.
I currently have a Sky+HD box, PS3 for blu-ray/dvd, and a yamaha soundbar - and herein lies the problem. The soundbar worked surprisingly well in our flat which was small and very square. We now live in a house with a much larger living room that has a massive bay window - and the soundbar now sounds awful/doesn't work well!
My initial thought was to get rid of the PS3 (i dont play games) & soundbar, and just get an all in one like Panasonic BTT 370 or the Sony BDV N590. However, I would ideally like to keep the PS3 as I've spent ages storing my music and dvd collection onto its 250G hard drive from my external hard drive.
Or, is there a speaker package that I could just add to the PS3/Sky box to give it good surround sound? I'm not totally against 2.1 sound set-ups either as I am used to having a sound bar/wide sound stage with no actual rear sound.
Lastly, I would also like to be able to play CD's/Ipod through the system so something that is decent with music is also important - apologies, I know this is a big ask.
