Well, let me start by first saying I am no audiophile. I have recently been on a get the most out of my PC phase and now i'm on to audio. I use my on board sound and play my audio with Winamp, Rock preset EQ. I have a 3 speaker (2 regular speakers, one big one with a bass hole or whatever its called.) Altec Lansing I bought from Costco a few years ago. I recently missed the $30 sound card that was a big deal on Amazon.com, but I wouldn't know how to tell if it would make things sound better anyway. I have an iPod but would like to replace it with a Zune within the next few months and am probably going to buy those Beta Brainwavez for it. I bought a pair of Koss KSC75 on Amazon a month ago for $15 and just now opened them. I usually prefer to play games and music through my speakers but may start wearing these for games for added immersion.
