The Matrix Audio mini-i Pro 4 Music Streamer/Headphone Amplifier is a compact all-in-one desktop audio component designed for high-resolution streaming, DAC performance, and serious headphone listening. With network streaming, digital inputs, balanced headphone output, and a clean touchscreen interface, it gives listeners a flexible hub for modern hi-fi systems.
Whether it is used on a desktop, in a headphone setup, or as a compact source for a two-channel system, the mini-i Pro 4 combines Matrix Audio’s streaming platform with a fully balanced amplifier circuit and ESS digital conversion.
System note: this is an excellent option for customers who want one compact component for streaming, DAC duties, and headphone listening without building a large stack of separate boxes.
The mini-i Pro 4 is built around a Quad Cortex-A55 platform and ESS ES9039Q2M DAC chip, giving it the processing and digital conversion foundation needed for high-resolution streaming and DAC use.

That makes the Matrix Audio mini-i Pro 4 Music Streamer/Headphone Amplifier a practical centerpiece for customers who use multiple headphone types or want a cleaner, more powerful desktop listening setup.
The 3.46-inch LCD touchscreen keeps control simple, while network connectivity, USB audio, optical, coaxial, and HDMI ARC support make it flexible enough for computer audio, streaming, and compact living room systems.
