Experience What's Made Luxman a High-End Standout for Ten Decades: L-505Z Integrated Amplifier Plays with Beautiful Purity, Features MM/MC Phonostage, Discrete Circuity, LECUA Control, and More
What would you do if you had a 100th anniversary to celebrate? If you're one of the finest audio manufacturers in the world, you might try to bring even more people into the fold by making an integrated amplifier that touts much of the signature performance, technology, and craftsmanship for which you're known — and price it at a level that makes it more accessible to a wider range of customers.
That's exactly what Luxman did with L-505Z, the entry-level model in the company's Z Series. Equipped with the Luxman Integrated Feedback Engine System (LIFES1.0), a LECUA volume control that extends to the balance control, and a superb built-in MM/MC phono preamplifier with a parallelized first stage, L-505Z offers music lovers a sonically astute one-stop solution to driving speakers and connecting source components — as well as a component you'll be happy to live with for years to come.
Built to exacting specs in Japan, the conservatively rated 100Wpc L-505Z comes with discrete buffer circuitry and high-current capability for the preamplifier stage to preserve the truthfulness of the delicate signals all the while supplying ample energy and output in the power-amplifier section. Also inside: An incredibly stable 540VA EI-type power transformer combines with four custom 10,000uF filter capacitors to provide instantaneous responsiveness for even the most challenging dynamics on your recordings.
Focused on purity, L-505Z touts beeline topology to minimize internal runs, oxygen-free copper wiring for enhanced naturalism, and spiral wrap shielding for every non-plated core wire. And since slight variations in ground impedance can lead to smearing, L-505Z adopts a loop-less chassis structure that looks as good as this amplifier sounds. More evidence of the extent to which L-505Z goes to set new precedents in its price class: Round-cornered asymmetric-printed circuit traces for smooth transmission, 18mm spacing between input terminals to accommodate beefy interconnects, and inline speaker terminals that allow for large-gauge cables.
On the front of the exterior, a seven-segment LED display and timeless white-illuminated VU meters — both defeatable — add touches of class and practicality. The elegant array of knobs and buttons extend to power on/off, bass and treble tone controls (yep, you get those too), balance control, speaker selection, cartridge selection, and separate. Not one but two headphone inputs — one a 4.4mm five-conductor balanced jack for independent right/left grounding, the other a standard 6.3mm type — round out the front panel along with the large, smooth volume control and input sector knobs.
When it comes to connectivity, the hefty 50-pound unit boasts a pair of balanced XLR inputs, four pairs of RCA line-level inputs, a phono input, phase inverters, and two pairs each of speaker terminals that allow you to hook up two pairs of loudspeakers should you wish. A 12-volt trigger input and output jibe with home-automation systems. Preamp output and power amp input further enable flexibility in the form of bi-amping and powered subwoofer connection.
Sold with a multi-function aluminum remote control, L-505Z exemplifies what high-end audio is about. You can read more about the standout technology in this unit below.

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. L-505Z is equipped with Luxman’s original, high-clarity LECUA electronically controlled attenuator, which adopts 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. 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.
Discrete Buffer Circuitry — And More
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. 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. L-505Z has achieved a dramatic development in musicality that far surpasses its class. Since vinyl record playback is an important contemporary source, a high-quality MM/MC compatible phono EQ amp circuit with a parallelized first stage is provided to realize supreme analog playback.
Proven Luxman Technology
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. Beeline 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 in ground impedance variations.
Headphone Terminals with Independent Grounding
L-505Z's high-quality headphone playback functions support the most intimate of listening environments. In addition to a standard φ6.3mm terminal, L-505Z has a 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 improved, three-dimensional, high-quality playback.
