hi i am wondering if one of you guys can help? i bought a cyberhomeadl 528 last month, and am now looking to buy some surround sound speakers. the dvd player has a digital 5.1 decoder built in, but my pal told me that i would still need an amp to put it through. i read somewhere else that i can buy a set of speakers and that is all i would need! can someone please help me?? much appreciated!
