Master Fidelity has unveiled the Nadac L preamplifier at the High End Show 2025 in Munich, expanding its esteemed Nadac series. This latest addition joins the Nadac D external DAC and the Nadac C reference clock generator, showcasing Master Fidelity's commitment to delivering ultra-precise audio components. Building on the expertise gained from designing the Nadac D, the Nadac L integrates a custom volume control chip developed in collaboration with a leading semiconductor manufacturer, utilizing a JFET-like custom CMOS ASIC architecture.

The Nadac L exemplifies Master Fidelity’s dedication to precision engineering with its true dual-mono architecture, ensuring complete isolation between left and right channels. This design minimizes crosstalk, providing superior imaging and channel separation. The audio path is meticulously crafted using ultra-precision 2 ppm resistors and high-quality hybrid capacitors, selected for their transparency and musicality. Additionally, the preamplifier features a super linear power supply architecture, including a custom toroidal transformer and multi-stage linear regulators, which collectively deliver a dynamic and noise-free power source suitable for the most demanding musical passages.

Technical prowess is further demonstrated in the Nadac L’s performance metrics. The advanced analog attenuation system offers channel imbalance of less than 0.1 dB, ultra-low total harmonic distortion plus noise (THD+N) of 0.00012% at 0 dB gain, and a high signal-to-noise ratio (SNR) of 132 dBA. Users can adjust the volume with 1 dB precision from 0 dB to –60 dB, ensuring seamless control without introducing noise. The front-panel peak level meters provide accurate real-time monitoring with an precision of ±0.05 dB, facilitating precise system tuning.

Connectivity options are versatile, featuring four balanced (XLR) and two single-ended (RCA) inputs, along with three balanced and one single-ended outputs, all independently controlled. The galvanic isolation between the analog audio circuitry and the digital control system preserves signal purity, eliminating interference and maintaining the integrity of the musical signal. The Nadac L’s true differential design for XLR connections and single-ended circuitry for RCA inputs ensure high linearity and maintain musical integrity under all conditions.

While the release date and recommended retail price for the Master Fidelity Nadac L preamplifier have yet to be announced, the introduction at Munich’s High End Show underscores Master Fidelity’s ongoing pursuit of excellence in high-end audio. Audiophiles can expect the Nadac L to deliver uncompromised sound quality, backed by meticulous engineering and superior component selection that set it apart in the competitive high-end audio market.
