Thought I'd update this now it's all set up, went for the Yamaha RXV477, with Tannoy HTS101 5.1 speakers and Cambridge audio symphony 300 speaker cable and oh my word I'm absolutely blown away! Coming from a Samsung all in one unit to this is pretty much night and day, I had no idea how good a sound system could sound!
But annoyingly when setting up the banana plugs didn't fit in the back, reading up on it it seems certain European models have smaller holes in the back to stop banana plugs being used, so spent quite a while fiddling about wiring it all up. Everything just sounds, and in a weird way looks just so much better.
Anyway I'll leave thanks here for the help in not only this thread but two others re cables and speakers.
