I like decent audio when watching films but I don't really want kit encroaching on my living space so I feel a soundbar will be a good option. What I'm wondering though is do they require an AV amp or do they plug direct in the the telly or Bluray player (PS3)? If they do would an AV amp enhance it or make no difference? I'd probably looking to spend £500-600 on the bar. Cheers chaps. Andrew.
