I can't tell the difference between a Macbook Air and a Magni 3 + Hifiberry DAC+ 2018-04-18 04:09:45 This will likely come as no surprise to the folks on this board, but ... In some of the headphone enthusiast communities which I frequent, there persists the belief that certain high impedance, low efficiency headphones like the Sennheiser HD 600 benefit from additional power in amplification and/or that there are audible differences between DACs. The counterpoint to this would be that all properly implemented amplifiers with sufficient power to drive a headphone to listening levels will sound the same and that all properly implemented DACs sound the same too.Well, I wanted to see for myself so I ran an ABX test. In short, I can't tell the difference between a Macbook Air's headphone out and a Schiit Magni 3 fed by a Hifiberry DAC+. I've got a more detailed writeup on Reddit.
