Luxman L-595ASE
ODNF and LECUALatest circuit
The L-595A SPECIAL EDITION incorporates the finest of LUXMAN’s latest circuit technologies. Our original ODNF feedback circuit, which achieves the highest initial slew rate, has evolved into the latest ODNF-u version with improved error detection circuitry. The volume control section uses the new LECUA1000 88-step electronically controlled attenuator, which minimizes sound quality deterioration at low levels, and a discrete buffer that increases the driving force of the preamplifier circuit. Copper-clad steel shielding protects the transmission path of delicate signals from external noise. The copper alloy RCA terminals have the conductivity of copper and hardness of brass.*LECUA : Luxman Electronically Controlled Ultimate Attenuator*ODNF : Only Distortion Negative Feedback
Commitment to Pure Class AFor irreplaceable musical expression
The L-595A SPECIAL EDITION operates in pure class A mode, eliminating crossover distortion during amplification. A rated output of 30W + 30W (8Ω) is generated by the power amplifier circuits. It's 3 stage Darlington equipped, triple paralleled push-pull configuration greatly improves S/N ratio and high-frequency distortion characteristics, bestowing a textural clarity and the drivability of a pre and power amplifier combination. The power supply section features a large, highly regulated power transformer with independent left and right channel high-capacity filter capacitors which combine to supply instantaneous power with great stability. And unique, vibration damped constructions are employed throughout. Large speaker relays with very low resistance achieve low impedance at the speaker terminals. All of these technologies contribute to achieve the finest level of musical expression expected from a pure class A product.
Unique LUXMAN design details and knowhowApplying accumulated LUXMAN technologies developed over decades
Design methods and housing structures are major factors that affect sound quality and timbre. Our goal was to design levels of deep musicality for the L-595A SPECIAL EDITION. The joint input/output circuit board is peel-coated without resistant green film coating which can cause high-frequency noise components. Smooth, rounded trace rounded trace patterns connect points on the custom-made, gold plated peel-coat circuit board.
A substantial and exceptional stereo integrated amplifierMulti-functionality and convenience
The L-595A SPECIAL EDITION combines the quality of a separate amplifier and preamp with the functionality of integrated amplifiers into a single unit. The built-in phono amplifier, with MM/MC compatibility, allows you to enjoy superb analog record playback. The unit features electronically controlled bass/treble tone controls and a volume-linked loudness function that matches human hearing characteristics. There are also perfect applications for different listening environments, such as a bi-amp configuration with an added power amplifier and the SEPARATE function that enables coexistence with the surround environment of an AV amplifier. In addition, we have included our premium RA-17A aluminum remote controller that can also operate compatible CD/SACD players.

Luxman L-595ASE — Pure Class A refinement with modern precision
The Luxman L-595ASE is a limited-edition integrated amplifier that pairs Pure Class A clarity with meticulous analogue engineering. Its sonic character emphasises textured midrange, taut low end and clean, unharsh treble thanks to the ODNF-u feedback, triple-parallel push-pull output stage and an oversized transformer that delivers engaging dynamics for a 30W/ch Class A design. Performance highlights include Luxman’s LECUA1000 88-step attenuator for ultra-precise, low-noise level control and a built-in MM/MC phono stage for vinyl systems. The 29kg chassis, hairline aluminium front and density‑gradient cast-iron feet underline exceptional build quality. Suited to analogue-focused audiophiles and compact high-end systems, the L-595ASE is a collectible statement piece with limited availability—endorsed in reviews by Tomasz Karasiński and Brian Mitchell.
Pros
- Superb mechanical construction and anti‑resonant design (heavy 29kg chassis, hairline aluminium finish and cast‑iron feet) that reduce vibration and reinforce longevity.
- Pure Class A amplification and advanced ODNF‑u topology produce very low distortion and highly detailed, natural textures.
- LECUA1000 88‑step precision attenuator and careful volume implementation deliver quiet, accurate level control with minimal channel imbalance or noise.
- Comprehensive analogue feature set—built‑in MM/MC phono, balanced inputs, PRE OUT and robust speaker relays—makes it a flexible hub for high‑end source components.

Cons
- No front‑panel VU or power meters, a stylistic choice noted by reviewers that may disappoint users who value visual power readouts.
- Limited‑edition positioning and premium SRP place it firmly in the high‑end niche, which limits accessibility for many buyers.

Dynamics
88/100
As a 30W/ch pure Class A design, dynamics expectations are restrained, but reviews note 'instant, effortless power' from an oversized transformer and large filter capacitors and claim stability into 2Ω. Those comments plus Luxman's implementation (high damping factor, low distortion) justify a strong dynamics score for its topology and power class.
Soundstage Imaging
88/100
Although reviewers do not focus heavily on explicit imaging metrics, repeated references to textural clarity, low distortion and improved error detection (ODNF-u) imply very good channel separation and image focus. The sonic clarity described supports a holographic, well-defined soundstage presentation.

Build Quality
94/100
Physical construction is highlighted throughout: heavy 29kg chassis, aluminum hairline front, two-tone finish, density-gradient cast iron feet and large speaker relays. Reviewers stress 'superb build quality' and a massive, well-damped presence, supporting an excellent build score.
Features Connectivity
89/100
Very strong analogue feature set: LECUA1000 88-step precision attenuator, built-in MM/MC phono stage, balanced line input (BAL.LINE), PRE OUT and high-quality speaker relays; remote included and tone controls present. Missing are digital inputs, DAC, streaming or HDMI, so the unit scores as well-featured in the analogue/high-end domain but not a networked/DA-capable hub.
Value for Money
89/100
SRP of $11,995 (limited to 100 North American units) positions this as a premium limited-edition product. Reviewers emphasize build, sonic refinement and exclusive presentation; while not framed as a bargain, the consensus is that the price is consistent with the level of engineering and finish—a justified premium rather than a mass-market value.
