Expert Audio Engineering Commentary

Headroom notes

FiiO gives peak-to-peak volts rather than Vrms: 12 Vp-p single-ended, 24.5 Vp-p balanced. Converted, that is 4.24 and 8.66 Vrms, and both agree exactly with the 300-ohm power ratings in the same table — a rare case where a manufacturer's numbers are internally consistent. Runs from a 12 V wall adapter, so USB supplies data only.

Amplification Warning

Output impedance is 1.2 ohms single-ended and 2.4 ohms balanced. For 300-ohm headphones that is irrelevant; for a 16-ohm IEM the balanced jack is the worse choice despite being the more powerful one.
