Luxman L-505Z Integrated Amplifier

Heartfelt Sound New Criteria That Redefines The Standard
Designed in honour of our L-505 amplifier, which continues to fascinate many audio enthusiasts as possibly our most familiar hi-fi model and equipped with our newly developed “LIFES” amplifier feedback engine, which is at the core of LUXMAN’s contemporary designs, we would like to complete the Z series circle with the L-505Z. While inheriting all the high-quality sound and design know-how from our higher-end models, it has achieved even more as a multifunctional integrated amplifier. Redefining the standard and now entering a new era, the L-505Z invites you into the world of exciting high-end audio.

Our Latest Amplification Feedback Engine Brings Music To Life With LIFES Version 1.0
The L-505Z, like the L-509Z and L-507Z, is equipped with our “LIFES” high quality amplification feedback engine, a feature integral to our next generation of amplifier designs. LIFES is based on the technical concept of our revolutionary ODNF feedback circuitry, which achieved excellent static characteristics without feeding back any of the musical input signal to the main amplifier, yielding a natural sound quality more akin to a non-feedback system. The circuit has been redesigned from scratch through multiple simulations. By combining carefully selected components and through repeated listening tests, we have achieved the ultimate performance and sound quality, truly worthy of being adopted for Luxman’s next-generation components. In LIFES Version 1.0, the entire circuit has been reconstructed and simplified, improving performance, whilst also successfully reducing the number of parallel elements, reducing distortion during amplification to less than half. The output stage uses a parallel push-pull configuration with bipolar transistor elements, achieving ample Class AB power of 100W+100W (8Ω) and 150W+150W (4Ω).
*LIFES stands for “Luxman Integrated Feedback Engine System”.
*ODNF stands for “Only Distortion Negative Feedback”.

Electronically Controlled Attenuator LECUA
The volume control section is crucial to both the functionality and performance of an integrated amplifier and requires dedicated signal processing. The L-505Z is equipped with Luxman’s original, high-clarity LECUA* electronically controlled attenuator, which has been significantly downsized by adopting a solid-state (IC) circuit configuration. LECUA is an ideal level control system that minimizes variations in audio quality and enables smooth and detailed volume adjustment over 88 steps. The LR balance adjustment control also relies on LECUA's volume shift function. Despite multitasking, LECUA succeeds in minimizing deterioration of sound quality across the full range of the volume control. Intuitive operability is maintained while linked with operations from the remote control. A traditional rotary volume knob achieves that weighty, tactile response and operational feel enthusiasts will enjoy, combining convenience with pleasing operability.
*LECUA stands for “Luxman Electronically Controlled Ultimate Attenuator”.

Discrete Buffer Circuitry For Preamp
The concept of a “power amp driver” is fundamental to the design of a preamp section, outputting an energy-rich signal is its ideal state of operation. The L-505Z is equipped with discrete buffer circuitry and high current supply capability at the output of the preamplifier stage, maintaining the fidelity of delicate musical signals whilst significantly enhancing the driving energy and performance of the power amplifier stage. The input selector switch controls a switching IC with excellent separation and low crosstalk. Proudly joining our latest Generation Z series, the L-505Z has achieved a dramatic development in musicality that far surpasses its class. In addition, responding to the reestablishment of vinyl record playback as an important contemporary source, a high-quality MM/MC compatible phono EQ amp circuit with a parallelized first stage is provided to realize supreme analogue playback similar to our other high-end components.

Highly Regulated Power Supply Circuit
The power supply is the beating heart of an amplifier and must supply instantaneous current and stable output voltages. The L-505Z is equipped with LUXMAN’s traditional, highly stable, 540VA large-capacity, EI type power transformer, combined with four custom-made 10,000μF filter capacitors. This combination provides the instantaneous energy required to faithfully reproduce the most radical or gentlest of musical dynamics and maintain a stable voltage supply under any load fluctuations.

Large Needle VU Level Meter And 7-Segment LED
Like our higher-end models, the L-505Z is equipped with large needle-type VU meters, highly visible with white LED back-lighting, that smoothly follow changes in the music signal. Between the left and right meters, a new 7-segment LED level display has been installed, allowing you to check the current volume level from your listening position. Using the remote control, you can turn the meter lighting and 7-segment LED on and off as you like.

Headphone Terminals With Independent Grounding
The L-505Z's high-quality headphone playback functions support the most intimate of listening environments. In addition to a standard φ6.3mm terminal, the L-505Z has a new φ4.4mm terminal with independent left and right ground wiring and separate unbalanced amplifiers, vastly improving left-to-right separation. By connecting compatible headphones and cables, the listener can enjoy further enhanced, three-dimensional, high-quality playback.

Various Functions And In/Output Terminals
The L-505Z has our proprietary tone controls, loudness, LR balance adjustment and a separate function, facilitating bi-amp configuration with an additional power amplifier or coexistence with an AV amplifier set-up, all in one unit. On the rear panel, the 18mm pitch RCA input/output terminals offer compatibility with high quality cables with large plugs, and the robust speaker terminals with an in-line layout (same LR characteristics) are compatible with Y-lugs and banana plugs.

Luxman’s Original Technology
The L-505Z is designed with sound quality as the top priority in every detail, including the non-angled wiring on the circuit boards that ensures smooth current transmission. “Bee-Line” construction informs component location, offering the most logical and shortest route for audio signals to travel. Internal wiring using OFC copper cable that ensures natural signal transmission with spiral wrap shielding for each non-plated core wire, and a loop-less chassis structure which suppresses increases in ground impedance.
