I recently picked up a pair of Beyerdynamic dt1990 pro's and they sound great. However, I am aware that since these are rather difficult headphones to drive that I should be in the market for some kind of AMP + DAC combination. Can someone tell me what would be more useful for me (dac or amp) or recommend something in the 200 dollar range that would help drive these cans better?
I am still using the on board audio on my PC and my audio source is Spotify.
Thanks in advanced!
