A palm-sized desktop USB-C DAC/headphone amp with an ESS DAC, a 3.5mm S-Balanced headphone jack rated at 211mW into 32Ω, RCA line outputs and Music, Movie and Game EQ modes, all powered over USB. It suits computer users who want cleaner sound on headphones or powered speakers without a separate power supply.
Who the iFi audio Uno is for
Computer desks: One USB-C cable from a PC or Mac carries both audio and power (5V/0.5A), so no wall adapter is needed.
Powered speakers: RCA line outputs (2V max) connect directly to active speakers or an amplifier.
Headphones and IEMs: The 3.5mm S-Balanced jack delivers 211mW into 32Ω with under 1Ω output impedance, and PowerMatch raises gain for over-ear headphones.
Movies and games: A button cycles Music, Movie and Game EQ modes; iFi says Movie mode lifts dialogue and Game mode brings out low-level effects.
Hi-res files: The ESS DAC plays PCM to 32-bit/384kHz, DSD256 and DXD, renders MQA, and shows the incoming format with a color-coded LED.
Skip it if: You need a 4.4mm balanced output or a mic input; the Uno has one 3.5mm headphone jack plus RCA line outs, and iFi says Windows PCs need its driver.
