Setup Guide
Do you need a DAC or amp, or just a better headphone fit?
Before buying a DAC or amp, check output level, noise, fit, seal, pads, tips, and EQ. Many listening problems start before the source chain.
FiiO makes sense when your listening problem is about clean output, inputs, portable power, or desk control. It should not be the first answer for every tonal complaint; fit, pads, tips, and EQ may solve more than a new box.
