Hello! I am new to the audiophile community, and just ordered my first pair of decent headphones, the Massdrop x AKG 7XX. I will be using these along with my MacBook Pro Retina Late 2014 (w/ Toslink) and Spotify Premium HD Streaming. I have heard that these headphones can be difficult to drive not because of their 62 ohm impedance, but from their 105 db/V (~93 db/mW) sensitivity, 200mW max power input, and high current needs. I am currently looking at the Schiit Audio Vali 2 Tube/SS Hybrid Amp (possibly along with the Magni 2 Uber DAC) and the Little Dot I+ 6JI X2. I have heard these two amps are good options in general, but I am not sure how they pair with the 7XX. I would love any suggestions, as again I am very new to this scene and do not know a whole lot about what exactly to look for. Thanks!
