The Harmony uDAC is designed with user comfort and seamless functionality in mind, ensuring an intuitive and effortless experience. A key feature that enhances usability is its dot-matrix display, which provides clear and detailed visual feedback. Unlike basic segmented displays, the dot-matrix screen allows for dynamic text rendering, making it easy to monitor input selection, sample rates, and operational status at a glance.
To further enhance convenience, the Harmony uDAC supports remote control functionality, allowing users to adjust settings from a distance. This is especially useful in desktop and high-end audio rack setups, where quick access to controls improves the listening experience. While the remote control is sold separately, it provides an added level of flexibility for those who prefer hands-free operation. By combining intelligent display technology with remote accessibility, the Harmony uDAC ensures a smooth, user-friendly experience while maintaining a sleek and elegant design.
Unibody CNC Aerospace-Grade Aluminum
Crafted from a single block of aerospace-grade aluminum using precision CNC machining, the Harmony µDAC delivers exceptional durability, a refined finish, and effective heat dissipation, all while exuding premium quality.
Galvanic Isolation for Enhanced Audio Purity
In high-fidelity digital audio systems, preserving signal integrity is paramount, and galvanic isolation between digital and analog components plays a crucial role in achieving this. By electrically decoupling the digital and analog sections, galvanic isolation eliminates unwanted ground loops and minimizes noise transmission, ensuring a cleaner, interference-free signal path. This results in lower jitter, reduced distortion, and improved overall clarity in audio reproduction.
Precision with Ultra-Low Phase Noise Femto Ocsillator with I²S Master Clock Synchronisation
The Harmony µDAC is engineered for great accuracy, featuring an advanced ultra-low phase noise femto ocsillator and the ability to integrate seamlessly with I²S master clocks. Together, these technologies ensure your audio remains impeccably timed and crystal clear.
Accusilicon AS318
Despite its small size, the ultra-low phase noise femto oscillator, designed by a Accusilicon, delivers remarkable precision and timing accuracy, ensuring pristine audio performance.
I²S Master Clock Synchronisation for Enhanced Flexibility
Utilizing I²S master clocks allows seamless synchronization with high-precision clock systems, delivering even greater stability and performance for audiophiles seeking ultimate sound accuracy.
LAiV Harmony R-2R Ladder Network Architecture
The Harmony µDAC harness the power of uncompromised sound to elevate your audio experience with LAiV Harmony R-2R ladder network architecture. Utilizing state-of-the-art technology, including Balanced discrete R-2R architecture and quality components, to deliver unparalleled sound quality.
Unparalleled audio fidelity with our advanced Balanced discrete R-2R architecture
An advanced audio technology that uses carefully arranged individual resistors with a tolerance of 0.05%, to achieve superior sound quality. By focusing on precision and quality, this technology delivers clear and accurate sound reproduction, providing an immersive listening experience with exceptional detail and fidelity.
Discrete Class A Output Buffer
The Discrete Class A Output Buffer in the Harmony uDAC is designed to provide superior impedance matching, ensuring optimal signal transfer between the DAC and the connected amplifier or headphones. By maintaining a low output impedance, it minimizes signal degradation and allows for longer cable runs without loss of fidelity. This is particularly beneficial in high-end audio setups where extended interconnect lengths are required, as it helps preserve the integrity of the audio signal over distance.
Due to its Class A operation, the buffer provides consistent linearity and low distortion, ensuring a pure and natural sound signature. However, as with all Class A circuits, it operates with continuous current draw, which results in a slightly warmer operating temperature compared to more energy-efficient designs. This is a normal characteristic of Class A circuitry and contributes to the smooth, refined sonic performance that audiophiles appreciate.
