SONCOZ LP1

High-Fidelity Ultra-Low Noise Linear Power Supply

Pure Power. Pure Sound. The Foundation of Your Audio System.

The SONCOZ LP1 is an advanced Linear Power Supply Unit (LPS) designed for the most demanding audio enthusiasts who understand that every nuance matters. In the world of High-Fidelity, power is the heart of the system—unstable current and mains noise are the primary enemies of signal purity. The LP1 eliminates these issues at the source, delivering perfectly stable, noise-free voltage that allows your devices (DACs, headphone amplifiers, streamers) to unleash their full sonic potential.

Designed as the perfect companion for SONCOZ digital-to-analog converters (such as the SGD1 or QXD1), the LP1 is highly versatile, making it an excellent upgrade for any audio equipment powered by 5V, 12V, or 15V.

Key Features and Technologies

1. Dedicated Custom Hi-Fi Toroidal Transformer At the heart of the unit lies a powerful, shielded toroidal transformer, designed and manufactured specifically for SONCOZ. Unlike cheap switching power supplies, the use of a toroidal transformer drastically reduces magnetic fields and vibration. The entire unit is fully potted (sealed in resin) to eliminate mechanical hum and ensure absolute silence, which is essential for high-end audio systems.

2. Advanced Voltage Regulation (Texas Instruments) To ensure a perfect power line, the LP1 utilises five ultra-low noise TI TPS7A4700 voltage regulators. These are laboratory-grade components characterized by extremely low intrinsic noise and high precision (high-bandwidth PSRR). As a result, the current reaching your equipment is crystal clear, translating to a "blacker background" in music and superior instrument separation.

3. Uncompromised Filtration The power path is supported by a bank of high-quality ELNA electrolytic capacitors, renowned for their excellent sonic properties. Combined with a modular rectifier design, this system effectively eliminates mains ripple, ensuring an instantaneous current response to the sudden dynamic demands of the music being played.

4. Flexibility and Output Configuration The SONCOZ LP1 is incredibly versatile. It offers independent power sections that can be activated via the front panel:

    DC Output (Jack): Users can select the output voltage between 12V and 15V (switchable via a button). This is the ideal solution for larger DACs or headphone amplifiers.

    Two USB Outputs (5V): Dedicated to smaller devices, such as streamers (e.g., Raspberry Pi), digital converters, or compact DACs.

5. CNC Machined Aluminum Chassis All electronics are housed in an elegant case machined from a single block of aluminum using CNC technology. The anodized finish not only gives the device a luxurious look but also acts as a shield, protecting sensitive circuits from external EMI/RFI interference. The minimalist design integrates perfectly with modern audio systems.

6. Intelligent Protection The device is equipped with a range of systems to protect your valuable audio gear. The LP1 features overload detection (signaled by flashing LEDs) and a memory function—upon restarting, the power supply restores the last used output configuration.
