Have you not thought about a Sound Projector, especially from Yamaha, I have the latest 30D model as it only fits on my AV Rack and does a commendable job of simulating 5.1 surround without the hassle of an amp and 5 separate speakers. Depending on your budget they do the YSP 600 below £400, mine is just over on Sound & Vision or Digital Direct and the 40D - Flagship is around the £600 or less. Both 30D and 40D have DAB radio built in. Just a thought/alternative to the norm!!!
I have your TV Model plus the BD-30 Panny Blu Ray Player a previous award winner.
