Matrix Audio MD-1P

The MD-1P is a different kind of product from anything else in the Matrix Audio lineup. Everything discussed on the NT-1, ND-1, MS-1, MS-1c, and SC-1 pages is about building a source chain — transport, DAC, clock, isolation. The MD-1P is the opposite approach: collapse the entire chain into a single chassis, add 300 watts per channel of power amplification, connect a pair of speakers, and stop there.

That is either exactly what you want or it is not what you want at all. If you are building a dedicated two-channel reference system where every component is chosen and upgraded individually, this is not the product. If you are building a serious system for a second room, a home office, or a living space where a stack of separates is impractical — or if you want a genuinely capable all-in-one that does not compromise where it matters — the MD-1P deserves a careful look.

The Amplifier

The MD-1P delivers 300 watts per channel into 8 ohms. The MD-1, its lower-powered sibling, delivers 150 watts into 8 ohms. Both will drive speakers from 2 to 16 ohms. The amplifier section uses high-efficiency switching topology with advanced PWM processing — Matrix's description of the technology is deliberately general, but the output impedance of under 3mΩ and SNR of 122dB A-weighted are the numbers that matter in practice. An output impedance that low means an extremely high damping factor, which is what gives a solid-state amplifier tight control over speaker drivers, particularly in the bass.

The MD-1P has two pairs of speaker terminals — gold-plated solid copper — allowing two pairs of speakers to be connected simultaneously and switched between via IR remote. A/B comparison between two speakers in the same room, or driving a second room from a single unit. The MD-1 has one pair. Speaker impedance for simultaneous A and B use is 4 to 16 ohms.

The Digital Processing Section

The DAC section uses a mastering-grade AKM chip — Matrix does not specify which in the consumer-facing documentation, but the dual femtosecond clock architecture and FPGA jitter reduction are the same design philosophy applied across the N Series. Two custom femtosecond clocks, one for 44.1kHz-based sample rates and one for 48kHz-based rates, feed a high-speed FPGA that handles frequency division and jitter reduction before conversion. Local playback reaches PCM 768kHz and DSD 24.58MHz.

Volume Control

The preamp section uses a 256-step digitally controlled analogue volume system — finer resolution than the 100-step control in the ND-1 and MS-1c. Range is -80dB to +12dB in 0.5dB steps, with algorithmic optimisation of the voltage output curve to maintain channel balance at low volumes. A 12-step channel balance compensation is available for speaker placement asymmetry. This is analogue attenuation with digital control — not a digital volume control that reduces bit depth, which matters at the power levels the MD-1P operates at.

Analogue Inputs

XLR balanced and RCA unbalanced line inputs handle any analogue source — maximum input levels of 8Vrms on XLR and 4Vrms on RCA, input impedance 47kΩ on both. A bypass mode disables the preamp stage and routes the analogue input directly to the amplifier, turning the MD-1P into a pure power amplifier for use with an external preamplifier or in a multichannel AV system.

A built-in MM phono stage covers vinyl — RIAA equalised, 47kΩ / 100pF input impedance, +40dB gain. It is voiced for MM cartridges only; MC users will need a step-up transformer or a separate MC stage.

Digital Inputs

Four optical and coaxial inputs handle set-top boxes, gaming consoles, CD transports, and Blu-ray players at PCM up to 192kHz and DSD 2.8MHz DoP. HDMI ARC carries audio from a television at up to PCM 192kHz. USB audio from a computer reaches PCM 768kHz and DSD 22.4MHz native. Bluetooth 5.0 supports aptX, aptX HD, AAC, SBC, and LDAC up to 96kHz — the LDAC codec in particular gives the Bluetooth input more resolution than most wireless implementations.

Streaming & Network

The MD-1P is Roon Ready and also supports Audirvāna, TIDAL Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA/UPnP, vTuner, and Radio Paradise. Gigabit Ethernet is the primary network connection; Wi-Fi 6 covers situations where a wired run is not practical. The MA Remote App controls everything from iOS, iPadOS, and Android. An NVMe SSD slot on the underside — M.2 2280/2242/2230, PCIe 3.0/4.0/5.0 — handles local library storage, with SMB sharing and NAS serving to other devices on the network. CD ripping via external USB drive is supported.

Outputs Beyond The Speakers

A preamp RCA output at 0–2.2Vrms with 120dB SNR and under 0.0005% THD+N allows the MD-1P to feed an external power amplifier or additional zone. A subwoofer output — also RCA, 150Hz fixed low-pass, 0–2.2Vrms — connects an active subwoofer directly, with the trigger output handling automatic power synchronisation. The MD-1P has dual subwoofer outputs; the MD-1 has one. A 12V trigger input and output handle system power sequencing.

Where It Fits

At 300 watts per channel with dual speaker outputs, a phono stage, HDMI ARC, and the full Matrix streaming ecosystem in a single 96mm-tall chassis, the MD-1P is genuinely capable of being the only component between your sources and your speakers. It is not a compromise product designed to cover all bases inadequately. The amplifier section has the output impedance and noise floor of a serious amplifier. The streaming section has the same femtosecond clock architecture as the N Series. The DAC section performs at a level consistent with the rest of the Matrix lineup.

Where a separates system still wins is in the ability to isolate and upgrade individual components — a better clock, a better DAC, a better power stage — without replacing everything at once. The MD-1P trades that flexibility for integration. For the right system and the right listener, that is the correct trade.
