I have got a 5.1 Samsung speaker set, PS DL-70 laying around and I have decided to use it with my PS3. I need to hook it up to an amplifier but don't know which amplifier should I buy. I mean what should I consider when buying the AMP. I got the manual for the speakers and here are the specs. Any recommendations are highly appreciated Note: Samsung sells the speakers with its own dvd player plus amplifier.
