I'm a tech and gaming enthusiast that has been lurking on Massdrop and the audiophile community for a little over a year. I'm looking to upgrade my audio setup at home but I do have a few questions and would love some feedback and recommendations. I currently have my PC and console running thorough my Astro A40s and Mix Amp. I have been eyeing the Fostex TX-00s now for the longest time and I am leaning towards those as my headphone upgrade (still open to opinions around $400 and below). I am, however, a lot less certain about my DAC upgrade. I enjoy the connectivity options of my current DAC/AMP its just really limited as far as audio quality goes. I do like having Dolby Digital decoding for surround sound and, if possible, I'd like to keep that capability when playing FPS. Are there any mid range DACs that can provide this or do you guys know of a solution? I have looked into Creative Sounds X7 but haven't been too impressed with some of the reviews. Should I just forget about 5.1 and become accustomed to stereo when gaming? I know there are a lot of knowledgeable people in the audiophile community and any help or opinions are welcomed.
