This Denon/Kef setup I've picked up sounds far better than I would have thought possible for the money. It really does sound awesome with movies and pretty damn good with music. Took a while to work out how to use the amp though
My only trouble now is that I didn't realise i'd need a Dolby Live sound card to output 5.1 game audio through the optical cable. I think the cheapest option for now would be to output through the 3.5mm jacks for game audio, and the opticlal cable for movies.
