I just found this little device to use with my new Dell XPS 13 laptop to get better audio out of it when I was on the run and this little device is quit good for the 40 bucks spent. I really just got it to make my headphones sound tolerable directly from my computer and it have beat that in spades. This little k1 paired with my Grado sr80i's are a killer little setup for the money and beats a hell of a lot of setups way more expensive. The K1 brings the low end out of the Grado's and makes them really sound great, probably better than any affordable Dac amp that I have paired them with in the past. Any one looking for a great little affordable dac/amp to try should give one a shot
