Matrix Audio Mini-i Pro 4

The entry point into Matrix Audio's world: streamer, DAC and headphone amp

The Matrix Audio Mini-i Pro 4 is the most accessible entry point into Matrix Audio's streamer lineup – and despite its compact footprint, it's not a stripped-down product. Network streamer, D/A converter and headphone amplifier come together here in a very small space, ideal for a desk, a shelf, or as a compact source in a smaller system.

At its core sits an ESS Sabre ES9039Q2M converter, known for its high resolution and very low noise floor. The headphone output comes in two flavours, a 4.4mm Pentaconn jack and the classic 6.3mm socket, so both modern balanced cables and existing headphone gear plug in without a hitch.

On the connectivity side, the Mini-i Pro 4 offers coaxial and optical inputs, USB-B for a computer connection rated up to PCM 768kHz and DSD 24.58MHz native, HDMI ARC, Ethernet and USB-C. Control is handled conveniently through the MA Remote app; the unit is Roon Ready certified and supports AirPlay 2, Audirvana, UPnP, plus Spotify Connect, TIDAL Connect, Qobuz and vTuner – available in black or grey.

Want more connectivity, an extra subwoofer output and more headroom? The slightly larger TS-1 is the natural next step on the same idea. The Mini-i Pro 4 remains the most compact, most affordable door into the Matrix Audio world.
