I want to buy the HE-400's for listening to edm and gaming, but I am unsure of what else I need to buy to make the full use of them and have Virtual 5.1 (or 7.1 if it's any good). I've seen in Mad Lust Envy's thread that he connects from his console to the Astro Mixamp to his e17, but that is just for gaming. Right now I have an old Creative Sound Blaster Titanium Fatality Pro that outputs optical to my Astro Mixamp. AFAIK my computer is outputting Dolby 5.1 and the Mixamp is also creating it's own simulated virtual surround and feeding that to my headphones right now.
I want to be able to use my HE-400's and have virtual surround sound from my games and at the same time be able to fully utilize lossless and FLAC audio. Will I need a better sound card, a high quality DAC, and a high quality amp? And if I do need any of those, what exact products would be best for me? They would be used strictly at my desk so nothing portable is necessary.
Edit: I feel like I just had an epiphany that my question was actually pretty stupid. It obviously should work if I go soundcard optical --> mixamp --> o2 amp --> headphones. The only question I have is: will my sound card or mixamp bottleneck my FLAC or lossless files?
Do NOT use the Mixamp for anything other than gaming and Dolby Digital enabled movies. You should NOT use it as a dac or amp for music, ever.
