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.

OePhi Lounge 2 and 2.5 – Compact Speakers with Very Precise Sound
The recently announced OePhi Lounge 2 and OePhi Lounge 2.5 speaker systems have gone on sale. The first model is designed as a bookshelf speaker and is aimed at small rooms, while the larger second speaker (made in a 2.5-way scheme), made in a floor-standing form factor, easily works even in large rooms.
Pro-Ject Head Box E – a Cool Headphone Amp for Only One Hundred Euros
Pro-Ject has released an entry-level headphone amplifier model - Pro-Ject Head Box E is available for 119 euros, and the small dimensions of the model allow you to easily place the device even on a heavily cluttered table.
Vandersteen Quatro Wood CT Evo — the Evolution of Iconic Speakers
Vandersteen Audio has introduced an upgrade of the famous Vandersteen Quatro Wood CT acoustic systems — the new speakers are called Vandersteen Quatro Wood CT Evo. Traditionally for the company, a scheme with active subwoofer sections in each speaker is used here. The acoustics has a stable impedance of 8 Ohms, but a rather low sensitivity of 87 dB — so, for operation, an amplification of 40 to 200 W is required.
Topping A900 – Headphone Amplifier with Record-Breaking Performance
Topping has released a truly powerful headphone amplifier – the Topping A900 model develops 2 x 22 W of power into a 16 Ohm load and achieves revolutionary performance – a dynamic range of 151 dB, a signal-to-noise ratio of 151 dB, and a THD+N distortion level across the entire frequency band (90 kHz BW) of 0.00003%!
