Micro Precision 5-Series 2-Channel Stereo Amplifier

Uncompromising Quality.

       Introducing the Micro Precision 5-Series 2-Channel Stereo Amplifier, a state-of-the-art audio solution designed for the discerning audiophile. This amplifier boasts a unique “Dual Board Design” that separates the power supply from the analog amplifier board, ensuring minimal radiation interference and preserving signal integrity. The result is a remarkably short and symmetrically designed signal path, crucial for maintaining detail and clarity.

Features &

Adaptive Power Supply: Accepts input voltages from 9V to 15.5V DC. The unregulated power supply adapts to higher input voltages for increased power output.

Voltage Step-Up Converter: Features a 12V step-up converter, providing rail voltages from +/-30V to +/-40V, adapting to input voltage or battery level.

High-Quality Capacitors: Utilizes high-grade, durable 105°C capacitors in all supply circuits, and “Mundorf MLytic®” Low ESR Power Capacitors at 125°C for main power storage.

Impedance and Selectivity: Offers a 12,000 Ohm impedance input with low capacitance. Includes a DIP switch selector for input level adjustment using 1% tolerance metal resistor dividers, eliminating potentiometers in the signal path.

Premium Transistors: Equipped with dedicated “Sanken®” Darlington transistors from Japan, ensuring solid-state technology with audiograde components, all hand-assembled without SMD.

Safety Features: Incorporates protections against reverse input voltage, output short circuit, DC voltage on speaker output, and thermal shut-off at 90°C using an analog sensor.

Optimal Connectivity: Features 4mm laboratory-grade banana terminals for a flawless speaker connection.

Efficient Circuit Design: The PCB is designed with wide copper tracks at 100 micron thickness, gold-plated to reduce internal resistance.

Balanced Current Circuit: Ensures low distortion, extended response, and stable bias during temperature fluctuations.


The Micro Precision 5-Series Amplifier is not just an audio device; it’s an investment in unparalleled sound quality and engineering excellence, making it a must-have for audio enthusiasts and professionals alike.
