My serious headphone amp died (I thought my ears would go first to be honest) so I decided to replace it with something a lot more portable. I was a bit skeptical that I’d get the kind of power I wanted out of such a small package but iFi must of used some kind of witchcraft on the tiny GO blu because it sounds like a serious piece of gear. Is it as rich as a wall powered tube setup? No, but it is surprisingly close and can deliver more power than most people can tolerate. The portability is worth the negligible trade-off.
