After visiting our son and hearing the quality of sound from his surround sound system my wife has decided she would like a surround sound system in our living room. Am I correct in thinking that these need to be powered from a dvd/amplifier? The problem is we already have a dvd player/hard drive recorder that is only 1 year old and we dont want to change it. We use it a lot for recording from tv and its invaluable. From the info in the unit handbook I think it wont serve as an amp for speakers etc. Is there any other way round this? For example are there speaker systems that have an amp built in? A lot of posts seem fairly technical. I would be grateful for simpler, easier to grasp answers for the untechnical myself. Grateful for any guidance.
