About the Matrix Audio MD-1
The MD-1 is Matrix Audio’s most affordable streaming integrated amplifier – a network streamer, DAC, preamp and 150W-per-channel power amplifier built into one chassis, so a pair of passive speakers is all that’s needed to build a complete system around it.
It shares its digital and streaming platform with the rest of Matrix Audio’s range, but adds a proper amplifier stage, a phono input and a wide set of TV and computer connections, aimed at anyone who wants one box to do the whole job. For more headroom or a larger room, the MD-1P steps up to 300W per channel with dual switchable speaker outputs.
Power and amplification
Output is rated at 150W per channel into 8 ohms, with output impedance below 5mΩ and +30dB of gain, enough to drive most bookshelf and floorstanding speakers with authority. PWM-based amplification keeps efficiency high and heat low compared with a conventional Class A/B design, and a single pair of Matrix Audio’s own gold-plated, solid copper speaker terminals keeps the connection to the speaker cable itself low-resistance.
Clocking, conversion and volume control
The digital side runs on two custom femtosecond clocks, one referenced to 44.1kHz and one to 48kHz, paired with an FPGA handling clock division and jitter reduction. The digitally-controlled analogue volume control provides 256 steps from -80dB to +12dB in 0.5dB increments. The voltage curve is tuned to keep left and right channels in phase even at low volumes, and it has a 12-step channel balance for fine positioning.
Sources and connectivity
A built-in MM phono stage with a RIAA-tuned, low-noise design means a turntable connects straight in, alongside XLR and RCA line inputs, with a bypass mode that turns the MD-1 into a pure power amp for an AV system.
On the digital side there’s HDMI ARC for a TV, USB for a computer, two optical and two coaxial inputs for other digital sources, and Bluetooth 5.0 with aptX HD and LDAC for convenient ad hoc streaming.
Preamp and subwoofer outputs share the same volume control as the speaker terminals, with a low-frequency output below 150Hz and a trigger connection to bring a subwoofer on automatically.
Storage and streaming
An NVMe SSD bay gives the MD-1 its own local library, shared over the network via SMB or as a NAS for other streamers in the house. CDs rip automatically from an external USB drive through the MA Remote App, turning a physical collection into digital files without a computer. Roon Ready, with TIDAL, Qobuz, Audirvana and the usual streaming services all supported.
