This high-end headp hone amplifier unlocks the vast depths of your music and infuses your audio system with new energy. Our Take With the NT series, Matrix Audio introduces a new family design language, equipped with the same Hi-Fi streaming hardware as the M Series. With a powerful core upgrade and a next-level display enhancement, it delivers a brand-new experience that captivates both your ears and eyes. The Texture of Fidelity As the newest addition to the Matrix Audio N Series separates Hi-Fi system, the NA-1 Headphone Amplifier delivers ample driving power, precise control and a pure, transparent sonic presentation. Whether driving full-size flagship headphones or serving as a preamp in a Hi-Fi active speaker system, it performs with effortless authority and composure - adapting seamlessly to a wide range of listening scenarios. The Discrete Class A Core The NA-1 features a fully discrete, pure Class A circuit design. Its fully balanced architecture employs four independent amplification units to effectively suppress common-mode interference during the amplification process. Building upon an excellent SNR and expansive dynamic range, it further minimizes distortion to ensure that every musical passage is conveyed with purity - infusing each playback with full-bodied and unrestrained energy. Order in Layers The NA-1 adopts a vertically layered circuit architecture. The preamp circuitry, along with the linear power and filter capacitor array, is located on the lower PCB, while the headphone amplification stage resides on the upper. By physically isolating the voltage and the current amplification stages, the NA-1 effectively reduces interference and thermal distribution is optimized. This ensures enhanced operational stability and improved heat dissipation efficiency - allowing the unit to perform with composure throughout every moment of pure listening. Dual Gain Modes Both the preamp and headphone outputs of the NA-1 feature independent dual-gain control. The high gain mode of headphone output provides increased voltage swing, effortlessly unleashing the potential performance of high impedance headphones. While the high gain mode of preamp output is ideal for power amplifiers and active speakers with lower input sensitivity, providing ample drive to restore authentic musical dynamics and fully reveal the purity of the sound. Diverse Connections The NA-1 is equipped with one balanced input and two single-ended inputs, allowing up to three audio sources to be connected simultaneously. On the output side, it features 6.35 mm single-ended, 4.4 mm and 4-pin XLR balanced headphone outputs, for flexible compatibility with a wide range of headphones. It also provides one XLR and one RCA pre-out, enabling seamless connection to a power amplifier or active speakers to accommodate diverse listening setups. Effortless Control With its high damping factor and ample power reserves, the NA-1 maintains abundant drive capability and sufficient power headroom even in large-scale, high-dynamic musical passages. With its precise control, the NA-1 effortlessly masters various flagship full-sized headphones, unleashing the full tension and grandeur of the music with complete authority. The Analog Soul With its high damping factor and ample power reserves, the NA-1 maintains abundant drive capability and sufficient power headroom even in large-scale, high-dynamic musical passages. With its precise control, the NA-1 effortlessly masters various flagship full-sized headphones, unleashing the full tension and grandeur of the music with complete authority. The Power of Poise The NA-1 features an independent, high-performance preamp circuit powered by 60V rails. This high-voltage design provides exceptional voltage swing and headroom, allowing the sound to remain effortless and spacious while maintaining a steady sense of power. Even at low volume levels, the audio remains rich in detail and full of dynamic impact. Seamless Volume Flow Equipped with an motor-driven quad-unit Type 27 potentiometer from ALPS, the NA-1 preserves the traditional approach to analog volume control with intuitive and straightforward operation. When changing volume via the IR remote control, the knob rotates smoothly and automatically - adding a tangible sense of ceremony to every adjustment. Renowned for its excellent channel-matching accuracy, the Type 27 potentiometer ensures consistent attenuation and stable dynamic performance across different volume levels. The Silent Power Source: The NA-1 Features an 80W Ported Toroidal Transformer Its potting construction effectively suppresses mechanical vibration and acoustic noise, while the metal magnetic shielding enclosure precisely blocks electromagnetic leaks - reducing noise at the source and creating an exceptionally black background for listening. Capacitor Array with Up To 39,000 µF Independent power supply design provides dedicated low-ripple, highly stable power for both the preamplifier and power amplification circuits, forming a robust electrical foundation for outstanding sonic performance. Rock Solid The NA-1 is equipped with the MA-DAMPER PRO isolation damper, jointly developed by 「Matrix Audio」 and Audio Bastion. Constructed from five materials—aluminum, stainless steel, rubber, isolation beads, and composite cork - they form a multi-layer damping and vibration-control system. This effectively absorbs and counteracts external mechanical interference. When paired with Matrix Audio's custom TEMPO DX RACK, the system works in precise synergy to create a comprehensive vibration-control solution. Masterful Engineering The N Series is not only a feast for the ears but a masterpiece to behold. Inheriting the design language of the Matrix Audio family, its precision-crafted CNC aluminum chassis infuses every detail with both tactile and visual refinement. It is our most restrained expression of craftsmanship, and our most profound tribute to the art of listening. Versatile Combination The NA-1 integrates with the Matrix Audio NT-1 Digital Audio Transport and ND-1 Audio DAC, forming a complete desktop Hi-Fi separates system that combines playback, D/A conversion, and amplification in one setup - adaptable to a wide range of listening scenarios. It can also be paired with the any 3rd party music players, DACs, amplifiers or active speakers. Flexible in configuration and highly versatile, it allows audiophiles to build a personalized high-performance audio system with ease.
