For the last couple of years my trusty Altec Lansing AVS 200's have stood by my side through countless hours of fragging, but it's about time they entered retirement. So, basically I'm looking to buy a nice set of computer speakers, namely the LOGITECH - Z-5500's. The thing is I do not have a separate sound card just the integrated audio on my Asus A8V deluxe motherboard. It supports up to 8 channel sound so the ports aren't really my problem, its the possible decrease in sound quality. My question is can I go through the S/PDIF port (coaxial or optical - is there a difference in quality?) or should I spend the money on a sound card? Also does anyone have any recommendation on brands of cables if I decide to go that route, i.e. what makes the monster cables so damn expensive?
