Matrix Audio MD-1 Streaming Integrated Amplifier One box, one pair of speakers, one genuinely great hi-fi system. The Matrix Audio MD-1 is a streaming integrated amplifier that com bines a full network streamer, a high-performance DAC with dual femtosecond clocks, a precision analog preamplifier, and a 150W per channel Class D power amplifier into a single chassis. Add a pair of passive speakers and you have a complete, high-quality hi-fi system with nothing left to buy, no interconnects to source, and no power supplies to match. The MD-1 handles everything from TIDAL and Qobuz over your network to vinyl from your turntable through the built-in MM phono stage, with a 256-step digitally controlled analog volume control and the full MA Player streaming ecosystem behind every source. It is Matrix Audio's answer to the question most audiophiles eventually ask: what if I could get all of this in one box without giving anything up? Available now at All Elite Audio, your authorized Matrix Audio dealer in Timonium, Maryland — with in-store demos, expert guidance, and nationwide shipping. 150W Class D Amplifier With PWM Signal Processing The MD-1's power amplifier section delivers 150 watts per channel into 8 ohms using a high-efficiency Class D design with advanced PWM (Pulse Width Modulation) signal processing. The PWM approach minimizes audio signal distortion across the power stage, ensuring the amplified output is an accurate reproduction of the input signal rather than a distorted, thermally compressed approximation. The high-efficiency topology achieves this power output with lower energy consumption and significantly less heat generation than equivalent Class AB designs, which means the MD-1 runs cool and operates passively without fans — completely silent in any listening environment. The speaker terminals are gold-plated solid pure copper, chosen for their low electrical resistance and reliable grip on speaker cables. Lower terminal resistance preserves fine signal detail through the connection point — a detail that matters when the rest of the signal chain is this carefully optimized. Speaker impedance compatibility covers 4–16 ohms, making the MD-1 a confident match for virtually any passive speaker. Dual Femtosecond Clocks With FPGA Jitter Reduction The MD-1's digital audio processing section is built around a dual femtosecond clock architecture using two custom Matrix Audio femtosecond oscillators — one dedicated to the 44.1 kHz sample rate family and one to the 48 kHz family. A high-speed FPGA implements Matrix Audio's proprietary clock division and jitter reduction algorithms, minimizing phase jitter and improving the accuracy of every digital audio sample processed. The FPGA handles automatic frequency division and switching between the two clocks as the source material changes sample rate. The result is what Matrix Audio describes as an "airy" quality to the sound — the sense of space and natural decay around instruments that comes from precise, low-jitter digital processing. 256-Step Digitally Controlled Analog Volume One of the MD-1's most significant engineering distinctions is its 256-step high-precision digitally controlled analog preamplifier volume system. Unlike mechanical potentiometers that introduce wear, channel imbalance at low volumes, and progressive signal degradation, the MD-1's volume control operates in the analog domain but is adjusted digitally — providing the sonic benefits of analog signal handling with the precision and repeatability of digital control. The volume range spans -80 dB to +12 dB in 0.5 dB steps, with advanced algorithms optimizing the voltage output curve to ensure perfect phase synchronization between left and right channels at every volume setting — including the low-volume range where conventional potentiometers typically suffer the worst channel tracking. A separate 12-step channel balance compensation allows fine-tuning of the left-right level balance based on speaker placement and listening room asymmetry. Bypass Mode — Pure Power Amplifier for AV Integration The analog inputs on the MD-1 can be configured to Bypass Mode, which routes the input signal directly to the power amplifier stage, bypassing the preamplifier volume control entirely. In Bypass Mode the MD-1 functions as a pure power amplifier, accepting a fixed-level signal from an external preamplifier, AV receiver, or processor and amplifying it directly. This feature makes the MD-1 genuinely useful in home theater systems where the AV processor handles volume and channel management — the MD-1 handles the two-channel power amplification while the processor controls the output level. Switching between integrated amplifier mode and Bypass Mode does not require any hardware reconfiguration. Complete Digital Input Suite — Up to Four Optical/Coaxial Inputs The MD-1 is designed as a hub for all digital sources, not just network streaming. Up to four optical and coaxial digital inputs accommodate multiple devices simultaneously — set-top boxes, gaming consoles, Blu-ray players, CD transports, or any other S/PDIF source can be connected and selected without unplugging anything. HDMI ARC enables high-quality audio from a compatible television. A USB Audio input accepts direct playback from a computer. Four digital inputs plus HDMI ARC and USB means the MD-1 can serve as the audio center for a complete living room or dedicated listening room without compromise. Analog inputs include balanced XLR and unbalanced RCA line inputs for external preamplifiers, DACs, or other line-level sources. The built-in MM phono stage with a precisely tuned RIAA correction curve accommodates a turntable directly — no external phono preamplifier required. Bluetooth 5.0 With LDAC For high-quality wireless playback from a phone or tablet, the MD-1 includes Bluetooth 5.0 with LDAC codec support. LDAC transmits audio at up to three times the data rate of standard Bluetooth codecs, approaching lossless quality for compatible source devices. This makes Bluetooth a genuinely useful secondary input rather than a convenience-only compromise — for streaming from a phone while the network streamer is busy or for guests who want to play from their own device, LDAC delivers quality appropriate to the MD-1's overall performance level. Preamp Output, Subwoofer Output, and Trigger Interface The MD-1 includes preamp and subwoofer output ports with synchronized volume control, allowing seamless integration with an external power amplifier or active subwoofer. The preamp output tracks the MD-1's master volume in real time, making it straightforward to add a monoblock or multichannel power amplifier to the system later. The subwoofer output precisely carries audio below 150 Hz to a powered subwoofer, extending deep bass without requiring a separate crossover. A trigger interface enables automatic power synchronization with an active subwoofer — when the MD-1 powers on or off, the subwoofer follows. NVMe SSD Storage With Dedicated Ultra-Low-Noise Power Supply An NVMe M.2 SSD slot on the MD-1 accepts a drive for internal music library storage, creating a self-contained music server alongside the streaming capabilities. The SSD slot has its own dedicated ultra-low-noise independent power supply — a level of isolation from the main digital processing circuits that ensures drive access activity does not contaminate the sensitive clock and audio circuits. NAS drives on the local network can be mounted directly for access to large remote libraries. Cloud storage can also be mounted. CD ripping is supported via an external USB CD-ROM drive. MA Player Streaming Ecosystem The MD-1 runs Matrix Audio's MA Player OS on a custom Linux platform, connecting via Gigabit Ethernet or Wi-Fi 6 on both 2.4 GHz and 5 GHz bands. Streaming services include TIDAL Connect, Qobuz Connect, Spotify Connect Lossless, AirPlay, DLNA, UPnP, and internet radio. The MD-1 is Roon Ready. The MA Remote app on iOS and Android provides full remote control of all playback, sources, volume, and settings. MD-1 vs MD-1P — Which Is Right For You? The MD-1 and MD-1P share the same streaming platform, DAC architecture, femtosecond clock system, 256-step volume control, connectivity suite, and chassis design. The differences are in amplifier power and speaker output configuration. The MD-1 delivers 150W per channel into 8 ohms with a single pair of gold-plated speaker terminals. The MD-1P doubles the amplifier power to 300W per channel into 8 ohms and adds a second pair of speaker terminals, allowing two pairs of speakers to be connected simultaneously and switched between via IR remote for A/B comparison. The MD-1P also adds a second subwoofer output for larger rooms requiring dual subwoofers. For most rooms and speakers, the MD-1's 150W is more than sufficient. For listeners who want the extra headroom for demanding speakers, very large rooms, or the dual-speaker A/B capability, the MD-1P is the right step up.

The Matrix Audio MD-1 is a streaming integrated amplifier that combines a complete network streamer, a high-performance DAC with dual custom femtosecond clocks and FPGA jitter reduction, a 256-step digitally controlled analog preamplifier, and a 150W per channel Class D power amplifier in a single chassis. It includes a built-in MM phono stage for turntables, Bluetooth 5.0 with LDAC, up to four optical and coaxial digital inputs, HDMI ARC, USB Audio, balanced XLR and unbalanced RCA line inputs, an NVMe SSD slot for internal library storage, and the full MA Player streaming ecosystem. Add a pair of passive speakers and the system is complete. What amplifier class and power output does the MD-1 have? The MD-1 uses a high-efficiency Class D amplifier with PWM signal processing, delivering 150 watts per channel into 8 ohms. The Class D design achieves this output with minimal heat generation and passive cooling — no fans, no thermal noise, completely silent operation. Speaker impedance compatibility spans 4 to 16 ohms. The speaker terminals are gold-plated solid pure copper for low contact resistance. What makes the MD-1's volume control special? The MD-1 uses a 256-step digitally controlled analog volume system that adjusts the signal in the analog domain with digital precision — no mechanical potentiometer, no wear, no channel imbalance at low volumes. The range spans -80 dB to +12 dB in 0.5 dB steps, with Matrix Audio's algorithms optimizing the voltage curve at each step to maintain perfect left-right phase synchronization even at low listening levels. A separate 12-step channel balance control allows fine tuning for asymmetric speaker placement. What is Bypass Mode on the MD-1 and when would I use it? Bypass Mode configures the analog input to route the incoming signal directly to the power amplifier stage, bypassing the MD-1's own preamplifier and volume control entirely. This turns the MD-1 into a pure 150W per channel power amplifier taking a fixed-level signal from an external source. It is particularly useful in home theater systems where an AV processor or receiver handles volume and channel management — the MD-1 takes the two-channel output from the processor and amplifies it without any additional level control in the path. How does the dual femtosecond clock system work in the MD-1? The MD-1 uses two custom femtosecond-grade oscillators — one optimized for the 44.1 kHz sample rate family and one for 48 kHz — managed by a high-speed FPGA running Matrix Audio's proprietary clock division and jitter reduction algorithms. The FPGA automatically handles frequency division to generate all derived sample rates from each master clock using integer ratios, and switches transparently between the two oscillators as the source material changes. This design minimizes phase jitter at the point of digital-to-analog conversion, contributing to the spatial clarity and timing precision in the MD-1's presentation. How many digital inputs does the MD-1 have? The MD-1 supports up to four optical and coaxial S/PDIF inputs combined, plus a USB Audio input for computers and an HDMI ARC input for television audio. All inputs are selectable without any hardware changes, making the MD-1 a practical hub for a complete living room or dedicated listening room with multiple sources. Can the MD-1 connect to a turntable directly? Yes. The MD-1 includes a built-in moving magnet (MM) phono preamplifier with a precisely tuned RIAA equalization curve, allowing direct connection from a turntable's phono output without any external phono stage. The phono input is treated with the same low-noise design philosophy as the rest of the analog input stage. What is the difference between the MD-1 and MD-1P? Both share identical streaming hardware, DAC architecture, femtosecond clock system, volume control, and input/output connectivity. The MD-1 delivers 150W per channel into 8 ohms with a single pair of speaker terminals. The MD-1P delivers 300W per channel into 8 ohms and adds a second pair of speaker terminals for simultaneous connection of two speaker pairs with IR remote A/B switching. The MD-1P also adds a second subwoofer output for dual-sub setups. The MD-1P is priced at $4,999 vs. the MD-1 at $3,999. For most rooms and speakers, the MD-1's 150W is more than adequate. For demanding speakers, very large rooms, or the dual-speaker capability, the MD-1P is the step up. What streaming services and formats does the MD-1 support? The MD-1 supports TIDAL Connect, Qobuz Connect, Spotify Connect Lossless, AirPlay, DLNA, UPnP, and internet radio natively through MA Player OS. It is Roon Ready. Supported formats include all major lossless and high-resolution PCM formats plus DSD playback. The MA Remote app on iOS and Android provides full remote control. Does the MD-1 support an NVMe SSD for local music storage? Yes. An NVMe M.2 SSD slot allows installation of a drive for internal music library storage. The SSD has its own dedicated ultra-low-noise power supply, isolated from the main digital processing supply, ensuring drive activity does not introduce noise into the audio circuits. NAS drives can also be mounted over the network, and cloud storage services can be mounted directly. CD ripping is supported via an external USB CD-ROM drive.
