The FiiO AIR AMP is a compact streaming amplifier that pairs a TI TPA3255 Class D stage, rated 120W + 120W at 4Ω on the included 48V/5A adapter, with an ES9020Q DAC and Roon Ready, AirPlay and QPlay streaming over Wi-Fi or gigabit Ethernet. It suits listeners who want one box to stream to a pair of passive bookshelf or small floorstanding speakers.
Who the FiiO AIR AMP is for
Passive speaker owners: The included 48V/5A adapter delivers 120W + 120W into 4Ω and 90W + 90W into 8Ω, which FiiO says is enough for most bookshelf and small-to-medium floorstanding speakers.
Roon and AirPlay users: Roon Ready, AirPlay and QPlay run over dual-band Wi-Fi or a gigabit Ethernet port, so no separate streamer is needed.
Local music libraries: It plays files from a NAS on your network or from a USB drive or portable hard drive, picked through the FiiO Control app.
Desk and TV setups: Two USB-C DAC inputs, optical, coaxial, RCA line in and Bluetooth 5.2 with LDAC cover computers, TVs and phones, and an RCA subwoofer out adds a powered sub.
Tone tweakers: Bass and treble controls (±10dB) sit alongside 10-band PEQ and AUTO EQ in the FiiO Control app or web interface.
Skip it if: you need HDMI ARC or a headphone jack; the AIR AMP has neither, so a TV connects over optical and headphones need a separate amp on the 3.5mm line out.
