Master Fidelity Nadac L Preamplifier - The Ultimate Preamplifier
04.06.2025 05:36 | ~1 minute read
Master Fidelity has unveiled the Master Fidelity Nadac L preamplifier, which features a dedicated volume control chip developed in collaboration with a semiconductor manufacturer using a JFET-like CMOS ASIC architecture. This analog gain control circuit delivers silent operation, less than 0.1 dB channel-to-channel imbalance, ultra-low distortion (THD+N) and a signal-to-noise ratio of 116 dB. Thanks to silicon-level design, the Master Fidelity Nadac L is claimed to achieve performance far superior to standard components.
The Master Fidelity Nadac L preamplifier is built using a dual mono design. The audio path uses ultra-precise resistors with a 2 ppm tolerance to maintain stability and ultra-low noise. The capacitors are high-quality hybrid models.
The Master Fidelity Nadac L features a linear power supply based on a custom-designed toroidal transformer. The power supply system also features a rectifier circuit to minimize AC-to-DC conversion losses. High-quality capacitor arrays provide ample power reserves, while multi-stage linear regulators reduce noise and optimize transient response. The Master Fidelity Nadac L preamplifier will be available soon, along with a suggested retail price.
