Luxman L-505Z

Overview

The Luxman L-505Z is a solid state integrated amplifier that carries the refinement and engineering philosophy of Luxman's celebrated 500 series into a modern, versatile package. Built around the company's proprietary ODNF (Only Distortion Negative Feedback) amplification circuit, now in an updated generation, it delivers clean, low distortion output with a natural tonal balance and an easy, unforced sense of flow that Luxman is known for. The result is an amplifier that combines high resolving power with a musical, listenable character.

Engineering highlights include the LECUA (Luxman Electronically Controlled Ultimate Attenuator) volume control for precise, low noise level adjustment, and a high damping factor output stage that grips demanding loudspeaker loads with authority. A discrete phono stage supports both MM and MC cartridges, and the amplifier offers a full complement of line inputs alongside a robust preamp and power amp section that can be separated for flexible system building. Careful attention to the power supply, chassis construction, and signal path reflects Luxman's century of engineering heritage.

The L-505Z is ideal for the listener who wants a genuine high end integrated amplifier with the control, transparency, and long term reliability to anchor a serious two channel system. It suits a wide range of loudspeakers and rooms, from detailed standmounts to full size floorstanders, and rewards careful source and cable selection with clarity and finesse.

How the L-505Z Compares

Luxman L-505Z vs Luxman L-507Z

The L-507Z sits one step above the L-505Z in the Luxman range and offers more output power, a larger power supply, and additional refinement in the amplification and control circuitry. Both share Luxman's core ODNF and LECUA technologies and the same musical character, so the choice comes down to the scale of your system and speakers. Move up to the L-507Z if you drive larger or more demanding loudspeakers or want more headroom in a bigger room. See the Luxman L-507Z.

Luxman L-505Z vs Accuphase E-3000

The Accuphase E-3000 is another Japanese high end integrated amplifier with its own distinct design goals, emphasizing Accuphase's signature smoothness and modularity with optional DAC and phono boards. The Luxman L-505Z leans on its ODNF circuit and LECUA attenuator for a clean, flowing presentation. Both are excellent anchors for a two channel system, and the decision often comes down to tonal preference and expansion needs. See the Accuphase E-3000.

Luxman L-505Z vs Yamaha A-S2200

The Yamaha A-S2200 pairs a floating, balanced amplification design with the brand's classic level meters and toroidal power supply for a full bodied, tactile sound. The Luxman L-505Z counters with its high damping factor and ODNF circuit for a refined, controlled character. Both suit listeners who value build quality and analog inputs, so choose based on the tonal signature that fits your speakers and taste. See the Yamaha A-S2200.

Recommended Speakers

The L-505Z combines high damping with strong resolving power, so it pairs well with speakers that reward control and detail across a range of efficiencies and room sizes.

• Marten Parker Duo Diamond Luxman and Marten are a natural pairing, and this diamond tweeter standmount rewards the L-505Z's transparency and control with fast, detailed, holographic sound in small to medium rooms.
• Marten Oscar Trio A more accessible Marten floorstander that still delivers the brand's clarity and coherence, letting the L-505Z's refinement and damping shine on a full range speaker.
• Amphion Argon 7LX Amphion's controlled directivity and neutral voicing align with the L-505Z's clean, resolving presentation, making for an accurate and room friendly system.
• Spendor Classic 100 This three way stand mount adds a warm, natural midrange that complements the Luxman's flowing character, and its load is well served by the amplifier's confident grip.
• Gauder Akustik Arcona 80 MKII SD Gauder Akustik's steep crossover design and high resolution benefit from the L-505Z's control and detail, delivering precise imaging and tight bass in medium rooms.
