Luxman L-509Z er Luxmans flaggskip blant de integrerte forsterkerene og en av de råeste produktene vi kjenner til!


Det er få produkter i butikken med større "må-ha-faktor" enn denne forsterkeren. Den ekstreme byggekvaliteten, den perfekte finishen, tyngden, det analoge utseende og ikke mins den silkemyke, fyldige lyden med krefter, anslag og driv i overflod.

L-509Z er Luxmans beste og kraftigste integrerte forsterker noen sinne. Den driver selv tunge laster med letthet og er bygget for å vare i generasjoner. Det er noe veldig tilfredsstillende ved å se de store VU-metrene danse i takt med musikken og vi tør påstå at L-509Z er DEN integrerte forsterkeren i butikken som gir oss størst eieglede og størst lyst til å lytte til musikk.

Informasjon fra produsent:


Our latest amplification feedback engine literally brings music to life with LIFES*

By feeding back only the distorted components generated in the audio signal’s journey to the final amp stage, LUXMAN’s proprietary “ODNF” amplification circuitry achieves excellent static characteristics and natural sound quality as if it were a “non-feedback” system. During the development of the M-10X flagship stereo power amplifier launched in 2021, technical concepts explored there were retained and the circuit configuration, which had become very complex over years of improvements has been completely redesigned to realize “LIFES” exquisite, high-fidelity sound and defines an amplification feedback engine blueprint for our next generation of components.

The L-509Z is equipped with independent LIFES modules operating simultaneously in each of its fully discrete pre and power sections. The L-509Z is a pre-main amplifier that is worthy of the “single-chassis separates” concept that incorporates quality seperate units into a single, elegant chassis and has achieved an elevated level of musicality and unprecedented detail in comparison to other amplification circuits. The output section utilizes three stage Darlington bipolar transistors in quadruple-paralleled push-pull configuration to achieve outstanding output power and near perfect power linearity performance comparable to a standalone power amplifier, developing 120W+120W at 8 ohms and 220W+220W at 4 ohms. The result is spectacular sound quality with an abundance of energy.

*ODNF stands for “Only Distortion Negative Feedback”
*LIFES stands for “Luxman Integrated Feedback Engine System”.


Electronically controlled attenuator LECUA-EX* incorporating an elaborate rotation mechanism

A tactile, satisfying volume control function is essential for audio amplifiers. To feed a fixed gain power amplifier with a musical signal at a level suitable for listening, precise control is required to smoothly attenuate the voltage while maintaining the quality of the input source. LECUA, developed by LUXMAN, is an electronically controlled attenuator system that switches through a series of high-quality, fixed value resistors for each channel independently. These are neatly arranged on the sub-assembly according to the position of the volume control knob.

Since the release of the C-1000f control amplifier in 2006 to commemorate LUXMAN’s 80th anniversary, “LECUA1000”, which similarly integrates into the amplification circuitry, has been used in many LUXMAN products as a volume control system that minimizes the effects of external vibrations and changes in sound quality across the operating range of the volume control and is also resistant to deterioration over time. The L-509Z combines a highly precise rotary encoder with a newly developed weighted rotation mechanism to create the “LECUA-EX”, which offers even greater reliability and a natural, high-quality operational feel. 88 fine steps from 0 to 87dB and an acceleration setting for the speed at which the volume knob is rotated and a long-press setting for the remote control allow for comfortable and thorough volume control action with minimal degradation in sound quality.

*LECUA-EX stands for Luxman Electronically Controlled Ultimate Attenuator - Excellent eXperience



Highly regulated power supply

The L-509Z is equipped with LUXMAN’s traditional, highly stable power supply circuitry, featuring a bespoke, highly regulated 600VA El transformer and newly developed large-capacity filter capacitors (10,000μFx 8).


High-quality phono EQ

The built-in high-quality phono equalizer circuit, which supports both MM and MC cartridges, features a new two-step gain switch to select between high and low MC settings to accommodate a wider range of MC cartridges, enriching quality vinyl playback in terms of both operation and sound quality. And a Mute-Button is now featured on the front panel.



3-band tone control

In addition to BASS and TREBLE, a new MIDDLE control effective in the vocal and lead instrument frequencies bandwidth has been included. LR balance, line straight, loudness, and other functions are also conveniently at your fingertips.


Original technology, special attention

Peel-coat circuit boards are used for the main audio signal path, eliminating the negative effects of the coating film that can adversely affect sound quality. Unique attention has been paid to every detail, such as the beeline construction, which configures circuits to take the shortest route possible, and a non-angled wiring pattern for smooth signal transmission.


Low-impedance transmission

Large, low resistance speaker relays are connected in parallel to transmit the driving force from the substantial power supply and output circuitry. Internal, 3.5mm2 ultra-thick cable is directly connected to the speaker terminals to ensure low impedance transmission, achieving a damping factor of 330 (current injection method).


High-quality hairline finish top panel

The top panel is made of ultra-thick aluminum with an exquisite hairline finish. Large ventilation holes are carefully machined one by one to ensure efficient heat dissipation. Supporting the unit are four large insulator feet made from cast iron, their density gradient protecting the main chassis from unwanted external vibrations.


Large needle-movement VU level meter and 7-segment LED

Needle-movement type analog VU meters are traditional design statement, proudly characterizing LUXMAN’s solid state integrated amplifiers. The L-509Z is equipped with two large meters, brightly back-lit by LEDs, with sensitive response characteristics. The newly included 7-segment LED display in between the left and right level meters displays the current attenuation amount and is easily visible from the listening position.


Headphones outputs with ground isolation

In addition to the φ6.3mm standard terminal, a φ4.4mm terminal with independent left and right grounding has been added for pleasurable headphone enjoyment. Using balanced cable equipped headphones improves L-R separation and localization, surrounding the listener with gorgeous three-dimensional sound.


High quality input/output terminals

Original high regidity RCA terminals are used for LINE-1 and 2. Separate inputs and outputs for system expansion are provided with two pre-outputs. Two large speaker output terminals with independent on/off switching allow for bi-wire connectivity.


Ergonomic aluminum remote control

The substantial, ergonomic aluminum alloy remote control can also operate compatible LUXMAN CD players released after 1996.
