Luxman L-505uXII: Perfection in Sound 

The Luxman L-505uXII Integrated Amplifier, a Mark II version of the esteemed L-505uX, represents the pinnacle of pre-amplifier design. With proprietary technologies such as the Version 4.0 ODNF and LECUA, this integrated amplifier is a testament to Luxman's pursuit of audio perfection, offering a sophisticated and authentic listening experience.

ODNF Version 4.0 - Advanced Feedback Circuit

Luxman's original ODNF amplification feedback circuit is a key feature of the L-505uXII. It ensures a high-speed primary slew rate, ultra-wide bandwidth, and minimal distortion by feeding back only the distorted components of the audio. This Version 4.0 ODNF circuit significantly enhances distortion detection and enables accurate reproduction of even the most delicate audio signals.

LECUA - Precision Volume Control

The heart of the L-505uXII's pre-amplifier section is the LECUA (Luxman Electronically Controlled Ultimate Attenuator). This computerized attenuator allows smooth, fine volume adjustment over 88 steps, minimizing signal deterioration and ensuring precise sound level control.

Discrete Buffer Circuit for Enhanced Clarity

The L-505uXII incorporates a discrete buffer circuit in its pre-amp output stage, similar to those found in Luxman's high-end separate amplifiers. This circuit significantly increases driving force to the power amplifier stage, thereby enhancing clarity and dynamism in audio reproduction.

Stable Power Supply for Consistent Performance

A stable power supply is critical for optimal amplifier performance. The L-505uXII utilizes an EI core type power transformer and four large capacity 10,000μF blocking capacitors to ensure a constant and stable current supply.
