The Matrix Audio MS-1c occupies an interesting position in the current landscape of digital source components. It is a device that refuses to be pigeonholed as merely a streamer or merely a DAC, instead functioning as an integrated digital hub built around a genuine femtosecond master clock and an unusually generous set of digital outputs. For the experienced listener who has already invested in downstream conversion or amplification, the MS-1c presents itself as either a complete source solution or a flexible transport, and that dual nature is the thread that runs through everything below.
What exactly is the Matrix Audio MS-1c?
The MS-1c is a network streamer and DAC in a single chassis. That combination means it can pull audio from your local network or from the internet, decode it internally, and present it to a power amplifier or preamplifier through analog outputs. At the same time, because it carries a full complement of digital outputs, it can also serve purely as a network transport feeding a separate outboard converter. The topology, in other words, is deliberately bifurcated: a network and rendering front end, followed by a conversion stage, with taps available before and after the digital-to-analog boundary.
Digital Architecture and Clocking
How does the MS-1c handle high resolution PCM?
The MS-1c supports high rate PCM playback, so it accepts and renders the elevated sample rate material that populates modern high resolution libraries and streaming catalogs. In practical terms, this means the rendering engine and the internal conversion stage are provisioned to accept files well beyond CD resolution without downsampling, preserving whatever additional information the recording actually contains. For an enthusiast, the relevant point is that the streamer does not become the bottleneck; the ceiling is set by your source material and your ears rather than by an artificially conservative input limit.
Does the MS-1c support DSD, and is it native?
Yes, the MS-1c supports native DSD. The word native matters here. Rather than converting DSD to PCM before playback, which would introduce an additional processing stage and defeat much of the reason listeners seek out DSD in the first place, the MS-1c passes the one-bit stream through a signal path designed to handle it directly. If your collection includes SACD rips or DSD downloads, this is the behavior you want, because it keeps the delta-sigma content in its original form as far into the chain as the architecture allows.
What does MQA support mean on this unit?
The MS-1c supports MQA, meaning it can process the folded MQA stream to recover the higher resolution content encoded within. MQA files carry their additional data in a compact, folded form, and a compatible device performs the unfolding and rendering necessary to reconstruct the intended output. For subscribers to services that deliver MQA content, having that decoding handled within the streamer itself avoids the need for an external decoder and keeps the entire process inside a single controlled environment.
Why does the femtosecond master clock matter?
The MS-1c uses a high precision femtosecond master clock, and this is arguably the single most consequential engineering decision in the unit. Clock jitter, the timing uncertainty in when each sample is converted, smears the reconstructed waveform and manifests audibly as a loss of focus, a flattening of the soundstage, and a hardness in the upper registers. A femtosecond-class clock reduces that timing uncertainty to an extraordinarily low level. Because the MS-1c can act as a transport as well as a converter, the quality of its master clock benefits not only its own analog outputs but also any downstream DAC that locks to the digital signal it produces, particularly over the interfaces that carry clock information most faithfully.
Network and Streaming
How does the MS-1c connect to your network?
The MS-1c offers both wired Ethernet and wireless networking. The wired Ethernet connection is the recommended path for critical listening because a physical link delivers consistent bandwidth and avoids the variability and potential noise associated with radio reception. Wireless is available for installations where running a cable is impractical, or for secondary systems where absolute consistency is less of a concern. Having both means the unit adapts to the room rather than forcing the room to adapt to the unit.
Which streaming services and protocols does it support?
The MS-1c is Roon Ready and supports TIDAL, Qobuz, Spotify, DLNA, and AirPlay. This is a broad and practically complete set of endpoints for most enthusiasts. Roon Ready certification means the unit integrates as a proper Roon endpoint with bit-perfect delivery and full transport control from within the Roon environment, which is the preferred ecosystem for many serious listeners managing large libraries. Native TIDAL and Qobuz support covers the two services most favored for high resolution streaming, while DLNA allows playback from local network shares and media servers. AirPlay provides convenient casting from Apple devices, and Spotify covers the largest mainstream catalog. The presence of both audiophile-grade and convenience-oriented options means the same unit serves both dedicated sessions and casual background listening.
How do you control the MS-1c?
The MS-1c is controlled through the Matrix Audio MA app. This dedicated application handles source selection, playback, and configuration from a phone or tablet, and it acts as the central point of interaction with the unit's streaming functions. For services that carry their own native control paths, such as Roon and AirPlay, you can also drive playback from those environments, but the MA app remains the hub for managing the device itself and for the services that route through it directly.
Analog Output Stage
What analog outputs does the MS-1c provide?
The MS-1c provides balanced XLR and single ended RCA analog outputs. This pairing gives you flexibility to match whatever comes next in your chain. The balanced XLR outputs use differential signaling, which cancels common-mode noise picked up along the interconnect and is the preferred choice for longer cable runs or for feeding balanced preamplifiers and amplifiers. The single ended RCA outputs serve the large number of components that use unbalanced inputs. Having both on board means you are not forced into an adapter or a compromise regardless of your downstream topology.
When would you use the analog outputs versus treating the unit as a transport?
You use the analog outputs when you want the MS-1c to be your complete source, converting the digital stream internally and handing off a line-level signal. This is the simplest configuration and it leans on the unit's own conversion stage and femtosecond clock. If, however, you already own a converter whose voicing you prefer, you can bypass the internal analog stage entirely and use the digital outputs described below, letting the MS-1c function strictly as a clocked network transport. The unit's architecture explicitly supports both roles without penalty to either.
Digital Output Section
What digital outputs are available on the MS-1c?
The MS-1c offers an unusually complete set of digital outputs: optical, coaxial, AES/EBU, I2S (IIS-LVDS), and USB. This breadth is one of the strongest arguments for the unit as a transport. It means that almost any external DAC, regardless of the interface it favors, can be fed directly. The optical output provides galvanic isolation by its very nature, since light carries no electrical ground path. The coaxial output is the common SPDIF interface over a single conductor. The AES/EBU output is the balanced professional digital standard, well suited to longer runs and to studio-grade converters. The USB output addresses DACs that expect a computer-style asynchronous input. The presence of all four alongside I2S is what elevates the MS-1c from a convenient streamer to a serious system anchor.
Why is the I2S (IIS-LVDS) output significant?
The I2S output, implemented here as IIS-LVDS, carries the clock and data on separate lines rather than embedding the clock within the data stream as SPDIF and AES/EBU do. In conventional single-wire digital interfaces, the receiving device must recover the clock from the incoming data, a process that can reintroduce jitter. By keeping the clock lines discrete over an LVDS physical layer, I2S preserves the timing integrity established by the source's clock and hands it to a compatible receiving DAC with far less degradation. For a unit built around a femtosecond master clock, this output is the most direct way to extend that clocking advantage to an external converter. The important caveat is compatibility: I2S pinouts vary between manufacturers, so this connection is best used with a downstream device explicitly matched to it.
Can the digital outputs pass DSD and high rate content?
The digital outputs are the mechanism by which the MS-1c passes its decoded and rendered stream to an external converter, and the interfaces that carry the clock and data with the greatest fidelity, particularly I2S, are the appropriate paths for the most demanding content. In practice this means that when you are running the MS-1c as a transport for native DSD or high rate PCM, the choice of digital output determines how much of that content and its associated timing precision arrives intact. The higher-bandwidth interfaces are the ones to reach for when format capability is your priority.
Interpreting the Design and Measurements
What does the clock specification tell us about expected performance?
A femtosecond-class master clock is the kind of specification that correlates directly with the qualities experienced listeners describe as low-level resolution and imaging stability. When jitter is pushed into the femtosecond region, the timing errors fall well below the threshold that would audibly degrade the reconstructed waveform, which typically presents as blacker backgrounds, tighter transient edges, and a more convincingly located stereo image. Because this clock also governs the digital outputs, the measured benefit is not confined to the internal DAC but is exported to any well-implemented external converter that can take advantage of it.
What does the combination of native DSD, high rate PCM, and MQA imply about the signal path?
Supporting native DSD, high rate PCM, and MQA within one device implies a signal path engineered for flexibility rather than optimized for a single format. Native DSD handling indicates a path that avoids forced PCM conversion, high rate PCM support indicates adequate processing headroom, and MQA decoding indicates the presence of the rendering logic that format requires. Taken together, these tell an experienced listener that the MS-1c is designed to render whatever the catalog delivers rather than to impose its own preferred format on the incoming stream.
System Integration Summary
How should an enthusiast slot the MS-1c into an existing system?
The MS-1c integrates in one of two clearly defined ways. As a complete source, connect it to your network by Ethernet, drive it from the MA app or Roon, and run its balanced XLR or single ended RCA outputs into your preamplifier or integrated amplifier. As a transport, ignore the analog stage and instead feed an existing converter through the digital output best matched to that device, ideally I2S for the tightest clock coupling, or AES/EBU, coaxial, optical, or USB as compatibility dictates. Either configuration lets the femtosecond master clock and comprehensive streaming support work in your favor, which is why the MS-1c earns consideration as a long-term anchor rather than a component you will quickly outgrow.
