Luxman L-509Z Integrated Amplifier

Combining the performance of separate pre and power components into a single rigid chassis, the flagship L-509Z represents a benchmark for Luxman and the design of high-performance Integrated Amplifiers. At its core is the newly developed LIFES feedback circuit, deployed simultaneously across both the preamplifier and power amplifier sections to correct signal distortion without diminishing musical warmth or dynamic flow.

Pure Sonic Clarity Across Every Frequency:

The LIFES amplification engine functions by isolating and cancelling only distorted components created along the audio path, resulting in a clean, natural playback performance. Supported by a robust power supply with a heavy-duty transformer and high-capacity smoothing capacitors, the amplifier produces 120 watts per channel into 8 ohms. This ensures reliable power delivery and clean linearity, easily driving demanding speaker designs across high dynamic peaks and subtle passages alike.

Uncompromising Volume Precision and Control:

Volume balance is managed by the LECUA-EX attenuator system, which routes the music signal through a succession of fixed resistors. A weighted rotary mechanism provides a smooth operational feel across 88 precise attenuation steps while preventing the signal loss associated with traditional potentiometers. For vinyl systems, the built-in phono equaliser accepts both moving magnet and moving coil cartridges, equipped with a two-step gain switch to accommodate low-output phono pickups.

Refined Sound Tailoring and Visual Feedback:

Beyond standard bass and treble adjustments, a middle control dial focuses specifically on vocal and solo instrument frequencies, allowing you to fine-tune the mid-range balance without muddying the rest of the soundstage. On the front panel, twin backlit VU meters provide immediate analogue signal monitoring alongside a modern digital decibel display. Internal peel-coat boards and direct circuit routes further protect the audio signal from interference from input to output terminals.
