Hi, It's been a while since my last post here. I avoided head-fi (for economical reason) and managed to save myself some money and built a new PC earlier this month. I need help on deciding an amp and/or sound card for $200. This time, budget is strictly $200 or under (if possible). I have 2 choices: 1. To go with a headphone amplifier + cheap sound card combo for $200, or 2. Buy a better sound card that has integrated headphone amp for $200. Which one do you think is better? The headphone amplifier that I want to buy is Fiio E9 or JDS Labs O2. The cheaper sound cards that I have in mind are Asus's/Creative's (I don't know which one is better). The better sound card that I want to buy will be Asus Xonar Essence STX. Currently using Fiio E10 with AKG Q701. I don't mind if my E10 will become unusable after I make this purchase. I usually play FPS games and listen to Rock/Metal/Pop music.
