Completely out of the blue, I was sent a Chord Mojo 2 this Christmas. What a gift! It’s a headphone amplifier and DAC (digital to analogue converter) and if you are interested in hi-fi at all, you’ve probably heard of it. And if you aren’t, you may have no idea what I’m going on about. To put it in layperson’s terms, it takes the music coming out of your phone and makes it sound like a million dollars. It’s a sonic rocket up the arse of dull-sounding digital tunes.
