At the moment I own a pair of in-ear Fidelio S2 for my mobile/on-the-go music and the reviews and opinions of the Fidelio X1 look pretty good. What would be a good bang for the buck to get the best out of these headphones, in a game like BF4 on a Sabertooth 990FX with Win 7 64 bit?
You can either go with just a soundcard and let it do the processing the DAC conversion and the amping (with it's integrated amp). OR you can just let the soundcard apply the virtual surround processing than send it out to an optical DAC then feed the signal to an external amp. The latter obviously costs more, but you could also use it for music listening too of course.
The X1s aren't hard to drive so you don't need a monster amp with them. An amp like the Magni would probably be overkill for them. The gain may be too high, forcing you to stay too low on the volume pot - where the channel imbalance issues are. I'm not sure if there are any other <$100 desktop amps with low output impedance and either low gain settings and/or lower power output.
