Meet the Matrix Audio NA-1
The Matrix Audio NA-1 is a dedicated reference headphone amplifier built around a fully balanced analog architecture. Matrix Audio made its name as a digital source and streaming specialist, and the NA-1 is the analog partner that lets those sources shine through demanding headphones. It is a pure amplifier stage, so it is designed to receive a line level signal from a separate DAC or source and drive your headphones with authority and control.
One thing to understand up front: the NA-1 is not a DAC and not a streamer. It does not decode digital files on its own. It takes an analog line input and amplifies it. That focused role is exactly what makes it a reference piece, because every part of the chassis is devoted to a clean, powerful analog output rather than shared with digital conversion.
Design and Technology
The NA-1 is housed in an aluminum chassis that reflects Matrix Audio's usual build discipline. Inside, the fully balanced analog architecture carries the signal through matched paths from input to output, which helps reject noise and preserve channel separation from the source to your ears.
Inputs and Outputs
On the input side you get both balanced XLR and single ended RCA line inputs, so it accepts whichever connection your DAC or preamp offers. On the output side the NA-1 provides a balanced XLR headphone output alongside a single ended (unbalanced) output. The balanced output makes the most of the fully balanced circuit for headphones that support balanced cabling, while the single ended jack keeps traditional connections easy.
Volume Control
Level is handled by a precision electronic volume control, which delivers repeatable, fine grained adjustment and keeps left and right channels tracking evenly at low listening levels. This is where an attentive volume stage really matters, and it is part of what earns the NA-1 its reference designation.
Sound and Performance Character
Because the NA-1 concentrates entirely on amplification, its character is one of clarity and grip. The fully balanced design and clean volume stage aim to let the source through without editorializing, so what you hear is largely a reflection of your DAC and headphones. That neutrality is a deliberate design goal: the NA-1 wants to be an accurate window rather than a flavor. Pair it with a warm DAC or warm headphones and it will convey that warmth honestly.
Where It Sits and What to Pair
Since the NA-1 needs a line level source, it is happiest fed by a capable DAC. The Matrix Audio ND-1 Audio DAC is a natural companion, keeping the whole chain within the Matrix Audio family and giving the NA-1 a clean balanced or single ended signal to work with.
If you also want streaming and want a single box that can act as a source, the Matrix Audio MS-1 Pre streamer, DAC and preamplifier can feed the NA-1 through its line outputs while adding Roon Ready, TIDAL, Qobuz, Spotify, DLNA and AirPlay via the MA app. The Matrix Audio TS-1 streamer and DAC is another source option that brings the same streaming platform to your setup. Note that the TS-1 has its own headphone stage, so pairing it with the NA-1 makes sense when you want a dedicated reference amplifier handling headphone duty.
Headphone Matches
The NA-1 rewards fine headphones. Open back designs suit its transparent, detailed presentation and give the widest sense of air and staging. If you prefer a closed back sound, wooden housed models tend to offer a rich, resonant tone, while lighter closed back designs bring an engaging character for everyday listening.
A Note on the Digital Chain
If you build out a network based source with Matrix Audio, remember that audio grade network switches, isolators and clocks serve the digital chain that precedes your DAC. They do not make sound on their own and they do not connect to the NA-1 directly. The NA-1 sits at the analog end, taking over once your DAC has done its work.
How It Compares
Within the broader category, AEA also carries the TEAC HA-507 pure analog headphone amplifier and preamplifier, and the Luxman P-100 Centennial headphone amplifier. Each of these takes its own design approach. The NA-1 leans on Matrix Audio's fully balanced philosophy and precision electronic volume for a transparent reference presentation, the TEAC pairs headphone amplification with preamplifier flexibility, and the Luxman follows Luxman's long standing house voicing. The right choice comes down to the character you want and how the amplifier fits your headphones and source, not a question of one brand outdoing another.
