Combining 80 years of innovation with passion and emotion, Luxman represents the embodiment of the very best in Japanese high end audio sensibility. Think Zanden, Kondo/Audio Note and Esoteric and you will know what I mean.


Since 1925 (no misprint!), Luxman has manufactured tube and solid state electronics of exceptional quality and performance delighting generations of audiophiles. Their current line up of preamplifiers, power amplifiers, integrated amplifiers and other electronics range in price from $2,000 to $48,000 per unit and express a level of sheer musicality we have come to expect from only the finest and most revered audio designers.

Luxman's build quality is like a Swiss watch. The grade of parts and circuit boards that they use in even their less expensive components are better than those employed by competing manufacturers in their most sophisticated models.



Sound By Singer is thrilled to be the exclusive dealer in New York for Luxman. If you have $7,500 or more to spend on an audio system, consider a Luxman amplifier for its engine.


The range of Luxman components is too vast to consider here in its entirety. A complete and thorough description of each one is available at: However, we would be remiss if we failed to make a brief mention of a few of our favorite Luxman components.

Consider their amazing integrated amplifiers, including the SQ-38U, L-505u, L-550A and L-590, tube separates Like the Cl-88 and MQ -88, and of course their remarkable “MINI SYSTEM” the SQ-N100 tube amp and D-N 100 CD Player.


With the D-N100 Compact CD Player you will enjoy a big musical performance from a small jewel-like musical box.

By cleverly hanging the transport mechanism from the top plate, the drive mechanism’s vibrations are isolated from the delicate electronics. This compact CD player upsamples regular CDs (44.1 Hz/16 bit) to 176.4 KHz/24 bit for a smoother, natural & more musical playback. Remote Control included.

As a noted critic recently observed:

"This is one sweet machine, a joy to use - with neat details llike a transport mechanism hanging from the top of the chassis to isolate it from vibration - and it upsamples regular CDs to 192kHz/ 24 bit. The sound is silky, non-fatiguing and a perfect match for the SQ-N100." Ken Kessler, Hi Fi News & Record Review (UK), May 2008


When Luxman set out to design the companion piece to the D-N 100 CD Player,the compact EL-84 based vacuum tube SQ-N100 integrated amplifier, they painstakingly researched every detail and individual component until each stage of the amplifier and preamplifier was created without compromise. With each design consideration came extensive listening sessions to be certain that the end result was one of the most musically satisfying integrated amps on the market. Only then did they feel that the SQ-N100 was ready to carry forward Luxman's tradition of building audio products that marry function and form in a beautiful package.




The NeoClassico design harks back to Luxman’s long tradition of producing superbly musical vacuum tube amplifiers. Connect your iPod and/or your record player. The SQ-N100 is remarkably compact and when matched with the D-N100 CD player makes a desk top /mini system of remarkable musicality that can easily be used in an office, den or bedroom.

"Even before switching them on, there's that whiff of satisfaction that only comes with the handling of a well crafted object."  Ken Kessler, HiFi News & Record Review, (UK) May 2008


Sixty five years in development; the SQ-38u is an heirloom to be passed down to the next generation of music lovers. Timelessness, meticulous craftsmanship, high aesthetic standards....

A first-class  work posseses these and many other rare qualities And when such a product is yours, ownership is nothing less than an exquisite pleasure.


The year 1963 was a watershed for audio equipment manufacturers. Vacuum tubes in TVs and other home electronic products began to be replaced with transistors. Meanwhile, many consumers sought out higher powered amplifiers. Luxman defied contemporary audio trends by releasing a high-quality integrated amplifier with 10W@ channel output that combined miniature triode tubes and OY output transformers. It didn't deliver a great deal of power, but its sound quality was so outstanding that it became a best seller. That's how the legendary SQ-38 came into being. It's now in its 11'th generation and retains the

original's aluminum front panel and wooden enclosure. Twenty & thirty year old models sell in Japan today for a higher price than their original retail price. This is truly an heirloom product.






The L-505u has been in continuous production for over thirty years and has quite often been Luxman's best selling single product. Of course it has been updated refined many times over the past thirty years.



The L-505f was introduced in 2001 and was remarkably successful as many proud Luxman owners will happily testify. Its successor, the L-505u, now has Luxman's unique noise & distortion canceling technology as well as the electronic input selector (trickle-down technology from the flagship C-1000f), which has lowered channel crosstalk; increased channel separation.

 The L-505u is a fully featured integrated amplifier, with a wonderful phono stage, multiple inputs (including one balanced), tone controls (easily defeated at the touch of a button), enough power to drive most speakers in just about any room in your home and a remote control to add convenience to a remarkably comprehensive integrated amplifier. It is a wonderful entrance to the world of Luxman.

Chassis bases have superb vibration absorption in order to supress noise levels. The power transformer, electrolytic capacitors and amplifer output stage are laid out so as not to interefere with each other. To reduce interference further, the block construction isolates each section using shielding panels, and extensive internal filtering to reject magnetic flux interference



Luxman holds many patents for audio engineering; among them is the application of  Global Negative Feedback to the output stage, which while widely used throughout the audio industry, they no longer use themselves.

Luxman nowadays use a distortion reduction circuit called Only Distortion Negative Feedback (ODNF). This system works by isolating amp noise distortion at the output from the music signal and sparingly applying negative feedback to suppress them. Conventional negative feedback systems can have an adverse effect on the music, introducing phase distortion. The circuit features such an ultra-wide range, ultra-high slew rate and ultra-low distortion that it does not use phase compensation for the music signal amplifying circuits. This new technology also ensures that need for a DC servo circuit is alleviated, again improving sound quality.

 Lux man introducd the first Class A amplifier in 1981.

Luxman introduced the L-550A and L-590A in 2005, since then they celebrated their 80th anniversary with commemorative components that have reaffirmed Luxman's status at the pinnacle of high-end audio. In these latest integrated models, the gorgeous texture and three-dimensional performance of our original Class A amplifiers has been retained and further refined. 
The latest iteration of these amps are the L-550AX and the L-590AX.
The LAX  series now uses a variation of the LECUA discrete volume control first introduced in the C-1000f.

Pure Class A
Thanks to the always-on nature of the topology and  the removal of an entire type of distortion, allied to sound that excels in a midrange liquidity, low-level detail, superb dynamics and transparency, its devotees are more than happy to put up with low efficiency and heat. What Class A always seems to offer above everything else is a tube-like sound without the maintenance hassle of tubes.

Input Selector 
The L-590Ax, L-550Ax and the L-509u, feature the new high quality electronic selector switch, which is the heart of the C-1000f pre-amp (one of Luxman’s 80th anniversary commemoration models). The sound quality deterioration using the new electronic input switch is now minimal, while channel separation and crosstalk efficiency were raised substantially in comparison with the L-550A / L-590A. In addition the illuminated position indicator around the input selector knob, makes it much easier to view the selected position even from afar.
Volume Control 
The integrated amplifiers also benefit from the C1000f in that they use a variation of the LECUA 1000 volume control. At any single volume setting only a few resistors are in circuit per channel. The less devices in the signal path, the purer the sound, the cleaner the music.
At low listening levels, potentiometers have trouble keeping both channels in balance,  so one channel might easily be 3dB louder than the other. With the volume control made of discrete parts, this is no longer an issue. 
Two Pairs of Speaker Terminals 
Large speaker terminals for driving two individual sets of speakers. At the turn of the speaker switch, it is possible to change between the two pairs of speakers easily. In addition, if the A+B function is used; Takasina capacitors are used to parallel the output which permits bi-wiring a single pair of speakers.

While the power rating improvement of the 590AX, vis-a-vis the L-550Ax, might not seem like a lot at first glance 30W versus 20W into 8 ohms, power is not the only consideration, the power supply is a lot more robust and capable of driving much more difficult speaker loads at lower impedances. The L-590Ax has a lot more finesse and reproduces music exquisitely. Notes are delivered against a blacker background, as the noise floor is lowered, so too are dynamics enhanced. The texture of the music is further improved, as is the soundstage definition; close your eyes and you will want to reach out to touch the musicians.




Many Luxman parts are custom made for them, which makes these designs truly special. Apart from the shared power supply, most amplifier designs are dual mono. Even the transformers are made according their exact specification.

Luxman select the color paint used on the resistors (to identify value and tolerance) based on extensive listening tests. The chassis are carefully tuned and both vibration and resonance are carefully controlled; they perform like a musical instrument.

Final assembly and testing is all carried on-premises. The attention to detail is fantastic: Luxman amplifiers come wrapped in a cloth shroud with elastic underneath; all of the RCA and XLR sockets are protected from oxidation with individual plastic sleeves. Even the power cord is a cut above the normal give-away and actually sounds good. No wonder Luxman achieves a superior sound.


Luxman's stereo vacuum tube control amplifier the CL-88 sports a precision brass four gang volume control featuring an in-built mute function. By touching the center of the volume control, the sound mutes at once.

Signal switching is performed by a golden switch immersed in a nitrogen container, located near the input terminals in order to maintain a low S/N Ratio











Also available are the MT-88 moving coil step-up transformer and EQ-88 moving magnet phono stage.

Luxman has a long tradition of producing some of the finest vacuum tube amplifiers in the world.


The MQ-88 has taken that tradition and incorporated some recent innovations in resonance and vibration control to raise the ante even higher. This is a classic tetrode design, where low distortion and linear output were chosen in favor of maximum power from the KT88 outpt tubes. The lower output from the output tubes will also help in a longer useful life of the tubes.


There are two sets of outputs on the MQ-88: variable, so that a single input (e.g. a CD player) can be connected directly ) and then the output to the loudspeakers can be adjusted. Or fixed, so that a separate preamplifier  (such as the partnering preamplifier the CL-88) can be using for switching between inputs as well as controlling the volume.

Bias is adjusted on the top panel, the bias meter is a convenient way to monitor each individual output tubes bias setting, to maintain optimum perfromance.
