My motherboard sound has been acting up lately. I've always been quite keen on moving to a headphone amp/DAC and right now it appears as a must. I would like the best of both worlds gaming and music. My idea was that I could run an internal or external soundcard for my surround sound gaming purposes and have this hooked up to headphone amplifier. The idea being that the headphone amp/DAC would be much more respectable for music listening. I am looking at something like the Sound Blaster Audigy Rx, it has all of the gaming surround features I would like but it also has a dedicated headphone amp/DAC, so I wonder if it would be overkill/waste to hook this up to a separate HP amp to never use the HP amp on the Sound Blaster? Should I perhaps be looking for a sound card that has surround features but needs amplifying?
