Created for higher-level audiophiles, this flagship separates system comprises three core components: the NT-1 Digital Audio Transport, the ND-1 Audio DAC, and the NA1 Headphone Amplifier. With versatile combination options, the N Series caters to the uncompromising pursuit, bringing greater refinement, presence, and a true sense of ritual to the desktop Hi-Fi experience. \u003c\/p\u003e\n\u003ch6\u003eThe Texture Of Fidelity\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 is the next-generation audio DAC meticulously crafted by Matrix Audio for separate Hi-Fi systems. Embracing a philosophy of simplicity, it focuses entirely on the critical aspects of D\/A conversion. With sound quality as its foremost priority, the ND-1 combines a rigorously engineered circuit architecture with professional tuning to deliver a clean, transparent, and low-distortion presentation. It's classic, warm tonal character faithfully reveals every detail and emotion of the music - crafted for audiophiles who seek the most authentic, delicate, and lifelike reproduction of the original recording.\u003c\/p\u003e\n\u003ch6\u003eTrue To Your Ear\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 features a custom-built ultra-low phase noise femtosecond clock, providing a high-precision reference signal for the D\/A conversion circuit. In addition, it incorporates a high-performance DPLL clock synthesis circuit derived from the brand’s flagship MS-1, supporting an external clock reference mode. When paired with the Matrix Audio SC-1 reference clock, the system’s full performance potential is fully realized—capturing the most delicate nuances and dynamic contrasts in music, and delivering a sound that is transparent, composed, richly layered, and vividly lifelike.\u003c\/p\u003e\n\u003cdiv class=\"builder-block builder-712fdabce6f14a1e97dc7c3d013d7581 builder-has-component css-mmcd1o\"\u003e\n\u003ch6\u003ePCM Resampling \u0026amp; DSD Conversion\u003c\/h6\u003e\n\u003cp\u003eYou can let the built-in asynchronous upsampling and DSD conversion engine process all the audio data in the digital stage. With asynchronous resampling and interpolation operations, jitters will be isolated, and details will be improved. The DSD converter transforms all playing audio into DSD, enhancing sound density. The processing engine features adjustable PCM or DSD conversion configurations, allowing you to experience the sound differences under different settings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"builder-block builder-2076fd6d58b2493eb9e72e300babd82e builder-has-component css-10xmv9c\"\u003e\n\u003cdiv class=\"builder-columns css-1fuo4gk\"\u003e\n\u003cdiv class=\"builder-column css-1lihfuk\"\u003e\n\u003cdiv class=\"builder-blocks builder-blocks-child css-h47494\"\u003e\n\u003cdiv class=\"builder-block builder-9d4e8a34052d4d3b9e4aea3031345e2a builder-has-component css-19ox3hq\"\u003e\n\u003ch6\u003eDual-Engine Core\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 features AKM's flagship chipset combination: the premium delta-sigma modulator K4191EQ paired with dual premium DAC AK4499EX. While the AK4191EQ handles high-precision digital processing and reclocking, the two AK4499EX chips use an independent channel architecture dedicated to the digital-to-analog conversion of the left and right channels. This '1+2' array architecture effectively suppresses jitter, optimizes channel separation and phase consistency, and achieves an exceptional signal-to-noise ratio and dynamic range. \u003c\/p\u003e\n\u003ch6\u003eMore Than Compatible\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 is equipped with XLR and RCA analog outputs and offers two selectable output levels. This allows the output voltage to be matched to the input sensitivity of downstream power amps or active speakers, achieving precise gain staging and preventing signal overload distortion or dynamic loss caused by insufficient signal level. In addition, it features a high-precision digital volume control with 100-step attenuation, enabling direct connection to a power amplifier or active speakers without a separate preamplifier.\u003c\/p\u003e\n\u003ch6\u003eOne DAC, Two Worlds\u003c\/h6\u003e\n\u003cp\u003eIn a bold departure from convention, the ND-1 utilizes prestigious Lundahl precision transformers for signal coupling in its output stage. Featuring a timbre switching function, it allows users to toggle between Transformer and Op-Amp output modes. In Transformer mode, the sound carries the distinctive warmth and rich, analog-like characteristics of Lundahl audio transformers. In Op-Amp mode, it presents a modern sonic signature defined by speed and high resolution - cleanly delineated lines, sharp transients, and precise retrieval of detail.\u003c\/p\u003e\n\u003ch6\u003eSource Of Purity\u003c\/h6\u003e\n\u003cp\u003eAdhering to our philosophy of circuit aesthetics, the digital and analog sections are strategically layered on two separate PCBs. The digital circuitry is located on the lower level, while the D\/A conversion stage resides on the upper, effectively minimizing interference. Powered by a multi-winding toroidal transformer and multiple LDOs, this fully linear power ensures exceptional performance for every circuit segment at the source.\u003c\/p\u003e\n\u003ch6\u003eRock Solid\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 is equipped with the MA-DAMPER PRO isolation feet, 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.\u003c\/p\u003e\n\u003ch6\u003eVersatile Combination\u003c\/h6\u003e\n\u003cp\u003eThe ND-1 integrates seamlessly with the Matrix Audio NT-1 Digital Audio Transport and NA1 Headphone Amplifier, 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 SC-1 Audio Grade Reference Clock for a comprehensive upgrade, or expanded with the SS-1 Pro to further enhance overall performance at the network transmission level. Flexible in configuration and highly versatile, it allows audiophiles to build a personalized high-performance audio system with ease. \u003c\/p\u003e\n\u003ch6\u003eMasterful Engineering\u003c\/h6\u003e\n\u003cp\u003eThe Matrix Audio N Series is designed not only to be heard, but to be admired. Inheriting the design language of the Matrix Audio family, its CNC aluminum chassis is meticulously sculpted, imbuing 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
