After about 2 years and tons of research I have the setup I've always wanted.
Asus Xonar Essence ST --> Blue Jeans LC-1 ---> Little Dot MK III ---> Beyerdynamic DT 880 (600 ohm)
Even though I am passionate about music I really bought this equipment for FPS gaming on my PC. Now that I am using the xonar only for the DAC and not the DAC+AMP I seem to have lost the ability to use Dolby Headphone.
Also, eve though the Little Dot has brought to life the Beyers and I do not regret the purchase, I seem to have lost some of that audio positioning us gamers love.
Anyone out there have a similar setup / interests that can provide some tweaking advice to get better positioning?
