First of all - Hi to all forum users! Please advise if you can as I am totally new to this. Just awaiting arrival of my TV - Sharp LC46XD1E and Denon DVD 1730. I have just bought a bargain KEF KHT 1005 speaker set and would like advice on how to get the best from these. Would I for instance be better off with an amplifier of some sort? Grateful for any advice!
