Internal view of the FiiO K7 and its converters

Two AK4493S

Conversion rests on two AKM AK4493S, one per channel, with an XMOS XUF208 USB stage ahead of them. Volume runs through two NJU72315 driven by a sampled potentiometer. Two gain levels cover impedances from 16 to 300 ohms.

6.35 mm and 4.4 mm headphone outputs on the front

THX AAA 788+ amplification

Two THX AAA 788+ modules carry the output stage. The 4.4 mm balanced socket delivers 2000 milliwatts per channel into 32 ohms and 560 milliwatts into 300 ohms. The 6.35 mm single-ended socket stays at 1220 and 140 milliwatts into the same loads.

RCA line output at the back of the K7

A hundred and twenty-eight decibels

Signal-to-noise reaches 128 dB on the analogue input and 120 dB over USB, for distortion of 0.0003 % into 32 ohms. Crosstalk exceeds 124 dB balanced. The RCA line output delivers at least 2 volts RMS.

USB, coaxial, optical and line inputs of the K7

Four inputs

The USB-B input rises to 384 kHz at 32-bit and DSD256; the coaxial input caps at 192 kHz/24-bit and the optical at 96 kHz. An RCA line input completes the set. An indicator changes colour with the incoming sampling rate, and the unit weighs 610 grams.
