Hi everyone. I have Koss porta pro and Fiio E10k and I am not sure if I should switch to sound card or external sound card(preferably)... I am a bit curious about it's special effects, dolby headphone and stuff described in mad lust thread. I find it a bit limitating having to connect headphones to pc front or back panel. That is the only reason I went for e10k few years ago, so I can connect headphones under monitor, behind keyboard. Speakers are also connected to this. I also have mxied feelings about e10k bass boost. The huge bonus is no drivers for e10k are needed. What is the opinion on this topic? Also... I can't be the only one using porta pro for desktop use and gaming right? The headphone sounds good and is so comfortable I am having difficulty finding anything else even at twice the price, so recommendations are also welcome.
