Expert Audio Engineering Commentary
Headroom Notes
All the audio figures are qualified UAC decoding, that is USB mode; FiiO publishes nothing separate for Bluetooth playback, where the same amplifier runs off the 460 mAh battery. The general table caps the whole device at PCM 96 kHz/16 bit, which is a real ceiling and unusual for a dual CS43131 dongle — the sampling-rate display exists mostly for Bluetooth codecs.
