I'm extremely new to the world of home cinema set up, and have what I feel will be a very basic question to a lot of people! I have a Sony 40" LCD Full HD television, with Sky HD and a Pioneer DV600-AV DVD player. I want to add surround speakers to my set up - what should I be looking for? I am right in thinking I need an amplifier with speakers? Where does the amplifier plug into? Also, do I buy an amplifier and speakers separate, or do they normally come as a package? Sorry for all the questions!
