Matrix Audio MD-1 Integrated Amplifier Music Streamer at Vinyl Sound Buffalo, NY

The MD-1 is a streaming integrated amplifier from Matrix Audio (Xi'an, China), available at Vinyl Sound in Buffalo, New York. Built on the same M Series hardware platform as the flagship MS-1 streamer, the MD-1 combines a Roon Ready network streamer, a mastering-grade DAC with dual femtosecond clock architecture, a full-featured preamplifier, and a 150W per channel Class D power amplifier into a single 7.0kg chassis. A 256-step digitally controlled analog volume system provides perfect channel balance at every level without mechanical wear, while an internal NVMe SSD slot with a dedicated low-noise power supply enables CD ripping and local library storage with NAS functionality. The MD-1 supports native PCM up to 24-bit / 768kHz and DSD up to 24.58MHz via USB Audio, and streams over Wi-Fi 6, Gigabit Ethernet, and Bluetooth 5.0 with LDAC, with full support for Tidal Connect, Qobuz Connect, Spotify Connect, and AirPlay 2.

150W Class D Amplifier with PWM Signal Processing

The MD-1's power amplifier delivers 150W RMS per channel into 8 ohms through a high-efficiency Class D stage employing advanced PWM signal processing technology. The amplifier's frequency response extends to 45kHz at -3dB, well beyond the audible range, and its SNR of 122dB A-weighted reflects the clean noise floor achievable when digital amplification is paired with a precision dual femtosecond clock and FPGA jitter reduction engine upstream. The output stage is stable into loads from 2 to 16 ohms, covering the full range of modern passive loudspeakers from compact bookshelf designs to larger floor-standing models. Gold-plated solid copper speaker binding posts minimize contact resistance and ensure a secure cable connection. An Amplifier Bypass mode removes the internal preamplifier from the signal path, allowing the MD-1 to operate as a dedicated power amplifier driven by an external AV processor for multi-channel home theater integration.

Dual Femtosecond Clocks and FPGA Digital Engine

The MD-1's digital processing section is built around a flagship DAC chip timed by two independent femtosecond clocks, one dedicated to the 44.1kHz sample-rate family and one to the 48kHz family. Separating the clocks by sample-rate domain eliminates the cross-domain jitter artifacts that occur when a single clock handles both families simultaneously. A high-speed FPGA implements Matrix Audio's proprietary clock division and jitter reduction algorithms, delivering a timing reference to the DAC chip at a phase noise level that produces an open, airy, and precisely imaged sound. USB Audio input accepts PCM up to 24-bit / 768kHz and native DSD up to 24.58MHz (DSD512). Optical and Coaxial inputs handle PCM up to 192kHz and DSD64 via DoP. An internal M.2 NVMe SSD slot with an independent ultra-low-noise power supply stores a local music library and exposes it over the network via SMB protocol, allowing the MD-1 to function as a music server for other streamers on the same network.

Complete Analog Hub: Phono, XLR, RCA, HDMI ARC, and Subwoofer Output

The MD-1 consolidates all the analog source connections a modern listening room requires into a single chassis. A built-in MM phono preamplifier with RIAA equalization, 47k ohm input impedance, and +40dB of gain accepts any moving magnet cartridge without an external phono stage. Balanced XLR and single-ended RCA line inputs handle sources up to 8Vrms and 4Vrms respectively. An HDMI ARC input transmits audio from a television at up to 192kHz PCM, while a USB Audio input connects a computer directly for hi-res and DSD playback. Four optical and coaxial digital inputs accommodate gaming consoles, Blu-ray players, and other digital devices simultaneously. The preamp RCA output delivers 2.2Vrms with an SNR of 120dB A-weighted and THD+N below 0.0005%, allowing the MD-1 to drive a separate power amplifier or active loudspeakers. A single subwoofer output with a 150Hz low-pass filter and synchronized volume control extends bass reinforcement to an active subwoofer, with the trigger output managing subwoofer power sequencing automatically.

Frequently Asked Questions

What is the Matrix Audio MD-1?

The Matrix Audio MD-1 is a streaming integrated amplifier from Matrix Audio that combines a Roon Ready network streamer, a mastering-grade DAC with dual 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 430 x 331 x 96mm chassis. It includes MM phono, HDMI ARC, USB Audio, four optical and coaxial digital inputs, a subwoofer output, Wi-Fi 6, Gigabit Ethernet, Bluetooth 5.0 with LDAC, and an internal NVMe SSD slot with CD ripping capability. It is available at Vinyl Sound in Buffalo, New York.

How does the Matrix Audio MD-1 compare to the Cambridge Audio Evo 150 or NAD M33?

The Matrix Audio MD-1 competes directly with high-power streaming integrated amplifiers such as the Cambridge Audio Evo 150 and NAD M33. The Cambridge Audio Evo 150 delivers 150W per channel and uses a Hypex NCore Class D module with a proprietary streaming platform and no phono stage. The NAD M33 uses a Purifi Eigentakt Class D module at 200W per channel with Dirac Live room correction but no HDMI ARC input. The MD-1 differentiates with dual femtosecond clock architecture shared with the M Series flagships, Roon Ready certification, a built-in MM phono stage, HDMI ARC, CD ripping via USB, internal NVMe SSD with NAS functionality, Bluetooth 5.0 with LDAC, and a subwoofer output with synchronized volume control.

Can the Matrix Audio MD-1 be used as a pure power amplifier?

Yes. Setting the MD-1 to Bypass mode disables the internal preamplifier stage and routes a line-level signal from the XLR or RCA input directly into the Class D output stage. In this configuration the MD-1 functions as a dedicated 150W per channel power amplifier driven by an external preamplifier or AV processor, making it suitable as the front left and right amplification channel in a multi-channel home theater system. All streaming, phono, and digital input functionality remains available for two-channel listening when not in Bypass mode.

Does the Matrix Audio MD-1 support CD playback and ripping?

Yes. Connecting any external USB CD-ROM drive to the MD-1's USB 3.0 port enables both direct disc playback and CD ripping to the internal NVMe SSD library. Ripped files are stored on the internal drive under a dedicated ultra-low-noise power supply and are accessible over the local network via SMB protocol. The MD-1 can also share its internal library with other Matrix Audio streamers on the same network, functioning as a music server for a multi-room system.

What is the difference between the Matrix Audio MD-1 and the MD-1P?

The Matrix Audio MD-1 and MD-1P share the same chassis dimensions, streaming platform, dual femtosecond DAC engine, digital inputs, MM phono stage, HDMI ARC, and MA Player OS. The key differences are power output and speaker terminal configuration: the MD-1 delivers 150W per channel with a single pair of speaker binding posts and one subwoofer output, while the MD-1P delivers 300W per channel with two pairs of speaker binding posts for A/B switching and dual subwoofer outputs. The MD-1P ships in matte black only, while the MD-1 is available in silver and black.

Where can I buy the Matrix Audio MD-1 in Buffalo, NY or the USA?

The Matrix Audio MD-1 is available at Vinyl Sound, located in Buffalo, New York. Vinyl Sound is an authorized Matrix Audio dealer serving customers across Western New York and the United States, with expert guidance on loudspeaker matching, system configuration, and subwoofer integration.

How does the 256-step volume control on the MD-1 work?

The MD-1's 256-step volume control is a digitally controlled analog attenuation system that adjusts level in discrete 0.5dB steps from -80dB to +12dB. Unlike a traditional potentiometer, which uses a continuous resistive track and a wiper contact that drifts over time and introduces channel imbalance at low volumes, the MD-1's system switches fixed resistor values in precise increments with no mechanical contact in the signal path. A separate 12-step channel balance control allows left-right level trimming for room asymmetry correction. Both the main speaker output and the subwoofer output track the same volume reference, maintaining a consistent balance between the main speakers and subwoofer at every volume setting.
