I have this sound card. This was a major upgrade over my previous sound card with Dolby headphone surround. I swapped out the OP amps for a pair of Sparko's Labs SS3602 and it got even better. I primarily bought the ZxR to improve my play on COD BO3, soon after buying this I sold my AKG K701 for a pair of K7XX then sold those for HD800s. This card runs all of them perfectly. If you like great sound this card will deliver. I also ran my PS4 through the optical so I could have excellent sound with the PS4 too, the card will do SBX for the PS4, so don't waste your money on a terrible Astro Mixamp when this can do your PC and console sound brilliantly.
