LUXMAN L-505Z Integrated Amplifier

Built to honor the legacy of LUXMAN’s beloved L-505 line while pushing the series into a new generation, the L-505Z is a full-featured integrated amplifier engineered around LUXMAN’s LIFES 1.0 amplification feedback engine for lifelike musical energy, low distortion, and effortless control. Its Class AB output stage uses a bipolar parallel push-pull configuration to deliver confident drive and dynamic headroom, while the LECUA electronically controlled attenuator provides ultra-smooth, high-clarity volume control across 88 steps—with precise remote operation and balance adjustment via volume-shift control.

Beyond power, the L-505Z is designed for real-world high-end systems: a high-quality MM/MC phono EQ supports modern vinyl setups, PRE OUT/MAIN IN connectivity enables bi-amping or integration with an AV system, and a thoughtfully laid-out rear panel offers 18mm pitch RCA terminals for premium cables. Up front, classic needle-type VU meters and a 7-segment LED volume display blend vintage appeal with modern usability, while headphone listeners get both a standard 6.3mm output and a dedicated 4.4mm connection with independent left/right ground wiring for improved separation and a more dimensional presentation. From LUXMAN’s “Bee-Line” signal routing concept to OFC internal wiring and a loop-less chassis structure, the L-505Z is tuned to deliver a refined, engaging sound that feels unmistakably high-end.

The LUXMAN L-505Z is part of ListenUp's LUXMAN Integrated Amplifier Collection.

What It's Good At:

• High-end musical realism at everyday usability thanks to LIFES 1.0 feedback design and carefully voiced circuit tuning
• Driving demanding speakers with authority via 100W/ch (8Ω) and 150W/ch (4Ω) Class AB power
• Vinyl playback done right with a built-in, high-quality MM/MC phono stage for turntable systems
• Precision listening at any volume using the 88-step LECUA attenuator for smooth, detailed level control
• Headphone listening with better separation through the dedicated 4.4mm output with independent L/R grounds
• System-building flexibility with PRE OUT/MAIN IN, tone controls, loudness, and separation features for bi-amp or AV integration

LUXMAN L-505Z Q&A:

Does the L-505Z have a phono input for a turntable?

Yes. It includes a built-in phono EQ stage that supports both MM and MC cartridges, making it ready for serious vinyl playback without an external phono preamp.

How much power does the L-505Z deliver per channel?

It’s rated at 100W + 100W into 8Ω and 150W + 150W into 4Ω, providing strong control for a wide range of speakers.

Can I use the L-505Z with an AV receiver or in a bi-amp setup?

Yes. With PRE OUT/MAIN IN connectivity and separation functionality, it can be configured for bi-amping with an external power amp or integrated into an AV-based system.

What is LIFES 1.0 and why does it matter?

LIFES 1.0 is LUXMAN’s amplification feedback engine designed to reduce distortion and enhance realism while preserving natural musical flow, contributing to a more lifelike, high-end presentation.

Is the volume control purely analog?

The L-505Z uses LUXMAN’s LECUA electronically controlled attenuator. It delivers smooth, consistent volume control across 88 steps while helping maintain sound quality at different listening levels.

Does it support balanced sources?

Yes. It includes a balanced line input (BAL.LINE) with specified sensitivity and impedance for integrating balanced source components.

What headphone connections are included?

You get both a standard 6.3mm headphone output and a 4.4mm output with independent left/right ground wiring to improve separation and clarity with compatible headphones and cables.

Can I turn off the meter lights and display?

Yes. Using the remote, you can switch the VU meter lighting and the 7-segment LED volume display on or off to suit your room and listening preference.
