Luxman L-509Z Integrated Amplifier with 120 Watts per Channel
Flagship Class AB stereo integrated amplifier • 120W + 120W (8Ω) / 220W + 220W (4Ω) • LIFES 1.0 amplification feedback engine • LECUA-EX 88-step electronically controlled attenuator • 3-band tone control (Bass, Middle, Treble) • discrete MM/MC phono stage with 2-step MC gain • dual needle VU meters with 7-segment LED volume display • handcrafted in Japan
The Luxman L-509Z Integrated Amplifier with 120 Watts per Channel represents the pinnacle of Luxman's "single-chassis separates" philosophy, uniting ultra-refined preamplification and robust power amplification into an iconic flagship component. Driven by Luxman’s revolutionary LIFES 1.0 (Luxman Integrated Feedback Engine System) circuitry and the ultra-smooth LECUA-EX computerized attenuator, this reference amplifier delivers 120 watts per channel of pristine Class AB power into 8 ohms and 220 watts into 4 ohms. Featuring dual illuminated analog needle VU meters, a discrete MM/MC phono stage with multi-step gain, 4.4 mm balanced and 6.3 mm headphone outputs, and a specialized 3-band tone equalizer, it sets a reference benchmark for musical transparency, harmonic realism, and effortless dynamic headroom.
Key Features & Innovations
Next-Generation LIFES 1.0 Feedback Engine — the Luxman L-509Z Integrated Amplifier with 120 Watts per Channel replaces ODNF with the innovative LIFES 1.0 topology, suppressing distortion to negligible levels while preserving the natural harmonic texture, breath, and realism of live instrumentation.
New LECUA-EX Electronically Controlled Attenuator — incorporates an ultra-precise 88-step computerized attenuator driven by a rotary mechanism with heavy brass weighting, ensuring perfect left/right channel tracking balance and zero signal degradation across all volume levels.
High-Inertia Power Supply with Massive EI Transformer — anchors the 120W-per-channel output stage with a custom 600VA high-regulation EI power transformer and dual 40,000μF filter capacitors, delivering explosive dynamic peaks and absolute control over low-impedance loudspeakers.
Audiophile MM/MC Phono Preamplifier with 2-Step MC Gain — features a built-in, fully shielded phono stage offering dedicated settings for Moving Magnet cartridges as well as Low-Gain and High-Gain Moving Coil cartridges, accommodating both modern and vintage low-output MC designs.
3-Band Tone Equalizer & Dual Headphone Outputs — introduces a dedicated "Middle" frequency adjustment alongside traditional Bass and Treble controls to fine-tune vocal bands, paired with both standard 6.3 mm (1/4") unbalanced and 4.4 mm Pentaconn balanced headphone jacks.
FAQ — Luxman L-509Z
How much power does the Luxman L-509Z Integrated Amplifier with 120 Watts per Channel deliver into 4-ohm speakers?
The Luxman L-509Z Integrated Amplifier with 120 Watts per Channel delivers 120 watts per channel into an 8-ohm load and scales up to 220 watts per channel continuous into a 4-ohm load, providing stable, high-current delivery for demanding low-impedance loudspeaker designs.
Does the L-509Z feature balanced inputs and outputs?
Yes. The back panel includes two pairs of premium Neutrik XLR balanced line-level inputs, as well as separate pre-out and main-in connections for external processor or bi-amplification integration.
Can the tone controls and display lights be completely bypassed?
Yes. Engaging the "Line Straight" function completely bypasses all tone and balance circuitry for shortest-path signal purity, while the meter switch allows you to dim or turn off both the VU meter backlighting and the central 7-segment LED volume display.
What headphone connections are supported on the front panel?
The L-509Z features both a standard 6.3 mm (1/4") stereo headphone jack and a 4.4 mm Pentaconn balanced headphone jack with independent ground wiring for high-performance audiophile headphones.
