hi all, i purchased the onkyo home theatre setup for my room (replacing computer speakers) but i thought the upgrade was subtle and not as impactful as anticipated. right now my setup is computer digital out -> receiver -> all standard cables that came with the box -> speakers/woofer. my roommate suggested that the cables should probably be replaced with higher quality ones, but i'm totally clueless as to whether this will make a big difference and if that is enough to improve the sound. i'm looking for anybody who can help me out, perhaps giving me specific items that i should buy from certain websites. if you own this particular setup and have configured it to your liking, please do share! thanks in advance.
