The short answer

The Luxman L-507Z is a Class AB integrated amplifier rated at 110 watts per channel into 8 ohms and 220 watts per channel into 4 ohms, built around the new LIFES 1.0 feedback engine and the 88 step LECUA1000 volume attenuator. Owners and reviewers describe pure, low grain tonality, dynamics that stay realistic without fatigue, and a muscular grip on speakers that runs well past the wattage rating. The Absolute Sound calls the combination of purity, balance, and dynamics hard to find at any price, SoundStage! Ultra says it is what its reviewer would buy in this bracket, and TONEAudio named it the 2022 Overall Product of the Year. It is $10,495 at All Elite Audio in Timonium, Maryland, where a used L-507Z is also available at $6,995. The honest caveats: an occasionally finicky volume control, a slight forwardness next to the flagship L-509X, a 56 lb chassis, and no DAC inside.

What is the Luxman L-507Z?

The L-507Z is the debut model of Luxman's Z series and the successor to the L-507uX Mark II. It is the first amplifier to carry the new LIFES 1.0 feedback engine, which replaces the ODNF circuit Luxman used for more than a decade. Per Luxman, LIFES is twice as sensitive at identifying unwanted distortion as the fourth and final generation of ODNF, achieved in part by reducing the number of paralleled elements in the circuit.

The output stage keeps what worked: the 3 stage Darlington triple paralleled push pull configuration Luxman has refined for years, here running in pure Class A for the first 1.3W RMS before transitioning to Class AB. A custom EI power transformer and eight 10,000 uF filter capacitors feed it, and the new 88 step LECUA1000 attenuator, first featured in Luxman's $20,000 C-900u control amplifier, handles the volume. The Z series philosophy is a 100 percent analog amplifier: there is no DAC inside, but there is a full MM/MC phono stage, tone controls, a loudness function, and headphone outputs in both 6.3mm single ended and 4.4mm Pentaconn balanced.

For many shoppers the L-507Z is the sweet spot of the lineup: the newest feedback technology, flagship derived volume control, and 110 real watts per channel in one chassis.

What it sounds like, in owners' words

A straight word on sourcing first. The L-507Z has a thinner owner footprint online than a flagship like the L-509Z. No dedicated discussion threads for this model turned up on Reddit, Audio Science Review, or the Steve Hoffman Forums in multiple searches, and owners mostly mention it inside broader Luxman threads. What does exist is consistent, and the professional reviews line up behind it.

The Absolute Sound put the core of it in a sentence:

"The L-507z presents music with an uncommonly pure, low grain tonality that isn't compromised by frequency response or dynamic trickery. This combination of purity, balance and dynamics is hard to find at any price and makes the L-507z an especially good value."

The Absolute Sound, L-507z review show notes

SoundStage! Ultra's Hans Wetzel, who lived with the L-507Z against his reference Hegel H590 and three pairs of speakers, came away with the strongest endorsement in the model's press file:

"Luxman's L-507Z is a fabulous integrated amplifier. Its sound is beyond reproach, being at once linear and dynamic, highly engaging yet non fatiguing. The Luxman is quiet, more muscular than its modest specs might otherwise indicate... And for that reason, Luxman's L-507Z is what I'd buy if I were in the market for a high four figure integrated amplifier."

Hans Wetzel, SoundStage! Ultra

And an original owner on Audiogon, selling only to make room for upgrades, put it the way owners do:

"I've really enjoyed the L-507Z... I have it paired with MartinLogan speakers and the combined sound is amazing and one I will certainly miss."

Audiogon listing, original owner

Five things owners and reviewers praise

  1. 1 Pure, low grain tonality

    This is the description that shows up in nearly every review. The Absolute Sound calls it "an uncommonly pure, low grain tonality," and hi-fi+ frames the same quality as its headline superpower. There is no etched treble trick, no midrange dip to fake detail. It is the LIFES circuit doing what Luxman claims for it: distortion identified and cancelled before it colors the music.

  2. 2 Dynamics that stay realistic without fatigue

    Reviewers keep pairing two words that rarely travel together: dynamic and non fatiguing. The Absolute Sound says the dynamics are "outstandingly realistic," and SoundStage! Ultra calls the sound "highly engaging yet non fatiguing." You can turn it up and lean in at the same time, which is exactly what the Dr. Dre and Nirvana sessions in the SoundStage! review demonstrated.

  3. 3 Muscular drive well past its wattage rating

    One hundred and ten watts per channel reads modest on paper. In the listening room it does not play modest. SoundStage! Ultra calls the L-507Z "more muscular than its modest specs might otherwise indicate," and proved it by driving 86 dB, 4 ohm T+A S 530 towers past the reviewer's highest likely listening levels with no compression and no clipping:

    "It was gratifying to drive my KEF Reference 3s... to insanely high levels, the L-507Z's VU meters bouncing wildly along the way. It never faltered."

    Hans Wetzel, SoundStage! Ultra

  4. 4 A deep, layered soundstage

    On solo piano the L-507Z painted "a soundstage that was not only deep but layered," with the hall extending "quite deeply beyond" the front wall. Vocal outlines are laser drawn between the speakers, and the reviewer repeatedly caught himself listening instead of evaluating, goosebumps and all. Transparency without editorializing is the thread: "no added tonal color or editorializing, no hash or edge, just wicked transparency to the source."

  5. 5 Owners reach the end of the upgrade road

    The owner voices are few but telling. On Reddit, an owner summarized the whole hobby in one line:

    "It gets different, but not better than this."

    Reddit r/audiophile owner, via thread summary

    Another owner on Audiogon runs the L-507Z with Klipsch Cornwall IVs and reports it sounds "great at low levels or rockin out." This is the pattern with the Z series: people buy it, stop shopping, and talk about the music again.

The features, named by name

Owners and reviewers keep returning to the same hardware. These are the features they call out by name:

  • LIFES 1.0. The Luxman Integrated Feedback Engine System, the debut of the Z series topology. It replaces the long running ODNF circuit and is, per Luxman, twice as sensitive at identifying unwanted distortion.
  • LECUA1000 volume attenuator. An 88 step electronically controlled attenuator that first appeared in Luxman's $20,000 C-900u control amplifier, now standard in the L-507Z for precise low level detail.
  • Backlit needle VU meters. The signature Luxman meters with soft white LED illumination and watch like mechanical movement, flanking a 7 segment red LED volume readout that can be dimmed or turned off from the remote.
  • MM/MC phono stage built in. A newly developed phono amplifier circuit for moving magnet and moving coil cartridges, no separate board to buy.
  • Tone controls, balance, loudness, and more. Bass plus or minus 8 dB at 100 Hz, treble plus or minus 8 dB at 10 kHz, plus balance control, a loudness function for low volume listening, a subsonic filter, home theater bypass, and a new front panel mute button.
  • Two headphone outputs. A 4.4mm Pentaconn balanced jack with independent left and right ground wiring for improved channel separation, alongside the standard 6.3mm jack, both pulled down from the amplifier section.
  • Full input and output flexibility. Four unbalanced RCA inputs, two balanced XLR inputs with adjustable phase control, RCA pre out and main in, and two pairs of speaker terminals for A and B operation.
  • Cast iron feet. Density gradient cast iron feet that protect the signal from vibration, plus beeline construction, a loop less chassis, and copper alloy RCA input terminals.
  • Custom EI transformer and eight 10,000 uF capacitors. A highly regulated power supply built for instantaneous current delivery, with direct wiring to the speaker terminals for a damping factor of 300.
  • RA-17A aluminum remote. A substantial machined remote that also operates Luxman CD players released after 1996, with 12V trigger in and out for home automation.
  • Made in Japan. Built at Luxman's Shinyokohama factory with a 3 year parts and labor warranty.

YouTube reviews

Honest criticisms

Nobody in print had a bad word for the L-507Z overall, but the reviews are specific about the nits. Here they are, in the reviewers' own words where possible.

The volume control is occasionally finicky

SoundStage! Ultra found the 88 step control could be hard to land exactly where wanted, whether by dial or remote:

"It scaled quickly and was sometimes difficult to dial in, with a remote button press sometimes resulting in a jump from, say, 48 to 50, and from 50 back to 48; it sometimes took several attempts to land on an indicated 49. Hardly a deal breaker, but annoying for sure."

Hans Wetzel, SoundStage! Ultra

A slight forwardness next to the flagship L-509X

In a UK dealer head to head, the consensus was that the L-509X was the better amplifier overall: "Playing the same recordings on the L-509X reduced the slight tendency towards brightness with the L-507Z, with more nuance and emotion to voices, and better dynamics to individual instruments." The dealer also stressed the L-507Z remains "a superb integrated amplifier," just not the flagship.

It is heavy

At 25.4 kg (56 lb) the L-507Z is a two person lift up a flight of stairs. The weight is the power supply and the chassis doing their job, but plan the rack position before it arrives.

No DAC inside

The L-507Z is a 100 percent analog amplifier. Streamers and disc transports with digital outputs need an outboard DAC, which is a feature for purists and a shopping item for everyone else.

The red LED display color

SoundStage! Ultra was not sold on the red 7 segment readout between the white lit VU meters: "Though I'm not the biggest fan of the color choice, the display does provide a digital readout of the unit's volume that can be easily seen from the listening position." It can be set to turn off automatically from the remote, which solved it for the reviewer.

How much does the Luxman L-507Z cost?

The Luxman L-507Z is $10,495 at All Elite Audio, an authorized Luxman dealer in Timonium, Maryland. A used L-507Z is also available in the store at $6,995.

Is the Luxman L-507Z a Class AB amplifier?

Yes. The L-507Z runs in pure Class A for the first 1.3W RMS and then transitions to Class AB, which is how it delivers 110 watts per channel into 8 ohms without the heat of a full Class A design.

How much power does the Luxman L-507Z make?

The L-507Z is rated at 110 watts per channel into 8 ohms and 220 watts per channel into 4 ohms. Reviewers report it drives well past those numbers in practice, including 86 dB, 4 ohm towers at very high levels with no compression.

What is the LIFES 1.0 feedback engine?

The Luxman Integrated Feedback Engine System is the feedback topology that debuted in the L-507Z and the rest of the Z series, replacing Luxman's long running ODNF circuit. Per Luxman it is twice as sensitive at identifying unwanted distortion, and reviewers credit it with the amplifier's grainless sound.

Does the Luxman L-507Z have a built in DAC or phono stage?

The L-507Z has a built in MM/MC phono stage. It does not have a DAC; the L-507Z is a fully analog amplifier, so digital sources need an outboard DAC.

What did the Luxman L-507Z replace?

The L-507Z succeeds the L-507uX Mark II and is the debut model of Luxman's Z series, bringing the new LIFES 1.0 circuit and the LECUA1000 volume attenuator.
