I've been using the G6 with a pair of Audio Technica ADG1X. I've just about ran every configuration I can think of, USB into PC, into PS4, and every combination of options with audio out settings and also Creatives software options and different buttons on and off. I have come to the point where I think I've found the best settings for myself to replicate the best positional audio for playing CoD. 5.1 Dolby via optical to the G6. USB to PS4 and chat only function to G6. SBX turned on. Low gain on. Playing with high gain is painful with harsh highs. Playing with low gain allows me to hear a wide range without being fatigued. I'm going to now switch between the G6 and the Astro Mixamp to see how they compare and I'll try that over a few weeks. But playing hard core search with a friend with the Astro and AD700X combo, we both tend to hear the correct directions from my observations. If you had to buy a mixamp / dac for PS4, I'd have no trouble recommending the G6.
