I Tried the FiiO Q15 and Discovered an Unusually Brainy and Brawny DAC/amp

Overall, I enjoyed my time with the FiiO Q15. It finally brings EQ to big-boy DAC/amps and can completely transform how one’s system sounds, provided the owner bothers to dial it in. Powerful enough for just about any headphones and sufficiently silent for IEMs, the Q15 is a Swiss Army knife but with the big blade of a Bowie.
