Hey all! I recently purchased the Beyerdynamic DT770 Pro 80 ohm headphones and am looking for an upgrade to the ****ty DAC in my PC tower. The one in my MacBook is supposedly pretty good and can output 96k, but my PC cannot. Need something I can use on my phone as well. I've looked at the SMSL M2, FiiO E10K, and a few others, but don't have anywhere nearby where I can test them. Any thoughts?
