The L-550AXII is an integrated amplifier with a pure Class A design, evolved from its predecessor, the L-550AX. It offers enhanced functionality with the latest technologies, such as the ODNF feedback circuit version 4.0 and the LECUA1000 computerized resistance. This amplifier is designed to deliver rich and dense sound, characteristic only of pure Class A amplifiers.

LECUA1000 Computerized Resistance

The new LECUA1000 computerized resistance, integrated into the volume adjustment unit, significantly contributes to the preamplifier section. It features 88 volume adjustment steps for smooth adaptation, reducing sound quality degradation.

ODNF Version 4.0

ODNF is LUXMAN's original feedback amplification circuit, designed for exceptional performance and improved distortion characteristics. The L-550AXII includes the latest ODNF version - Version 4.0, which offers upgraded performance in high frequencies.

High-Capacity Power Supply Circuit

The L-550AXII amplifier features a high-capacity power supply circuit with a large EI power transformer and 10,000uF x4 electrolytic capacitors, providing stability and dynamic sound.

Discrete Buffer Circuit

A discrete buffer circuit ensures the purity of audio signals while enhancing the driving power of the power amplifier.

Low-Resistance Transmission

The high-capacity audio contacts are connected in parallel, ensuring stronger audio power transmission without losses.
