HiFi Rose Silver Integrated Amplifier

Linearity dramatically improved to create a near-perfect sound

Power damping and dead times reduced to 1/10 or less

Transcends the boundaries between digital and analog

This amplifier has developed from Class A to Class AB to Class D. Class AB was developed to improve the high heat generation and low efficiency of A. Class D has higher efficiency and higher output than AB, and also significantly improved S/N and THD characteristics compared to A and AB. However the sound quality has been evaluated as inferior to A/AB due to limitations of the digital circuit. The GaN class AD amplifier developed by HiFi Rose has dramatically improved the problems of the existing Class D by applying innovative new materials.

Class D amplifiers have a topology that theoretically provides a perfect linear output at 0% distortion and 100% power efficiency. In order to achieve this, the switching action requires high speed and accuracy. However, previous products were weak compared to Class A/AB in the linearity aspect due to the limitations of silicon FET, which couldn't produce a smooth and natural sound. In the RA180, a new material, GaN FET, was used instead of Silicon FET to solve this problem. The dead time was dramatically improved to 1/10 or less, and a nearly perfect linear output was realized with a switching speed close to zero. This linearity goes beyond the Class D limits and produces a smooth and natural sound, like an analog amplifier.

The RA180 consists of two modules: one AMP module specialized for stable mid-bass and balance, and another specialized for smooth, high-pitched and and super tweeter areas. Each AMP modules supports 200 W (8 ohms) and can output up to 400 W per channel. When two independent modules are connected to a speaker's high and low frequencies separately, the driving force can be greatly improved without being affected by a counter electro-motive force. BTL mode combines two independent modules for rich, balanced sound.

Designed to Play Up to the Super Twitter Realm

The human hearing range has an upper limit of 15-20 kHz. So, is there no need for higher frequencies? Temporarily high trebles extend well beyond 20 kHz, even in harmonious sound. For example, trumpets have a frequency response that extends to 100 kHz, and 88.2 kHz to 192 kHz sources have a 40 kHz to 96 kHz frequency response. The RA180 is designed with a wide frequency response range so that even high resolution sound sources with an output range of 20 Hz to 50 kHz, 100 kHz at -3 dB, 200 kHz at -6 dB. Although this playability may be outside a person's hearing range, it faithfully reproduces a frequency range, which contributes to expressing a deep and wide sound field with the original sound.

The power supply that has been exclusively developed for the RA180 applies 4th generation SiC FET technology to provide high output with less heat. In addition, by using a self-developed PFC (Power Factor Circuit), it is designed not to be affected by sudden load fluctuations. The power supply device was developed to support a powerful damping factor of at least 200, and the high output of 1000 W is designed to produced powerful bass and soft treble.

The purpose of the PHONO amplifier provided by the RA180 is for the recording producer to accurately reproduce the original intention. It also reproduces the original sound as it is, which is the principle of HiFi Rose. It is designed to respond to a variety of vinyl records with low-mid bass turnover and high frequency roll off adjustment functions. Moving magnet and moving coil stages are provided with a simple switch selection and EQ values corresponding to curves from various record manufacturers are provided using parts with a 0.1% tolerance.

The RA180 is a state of the art integrated amplifier using the latest innovative technologies. Power damping and dead times were reduced to 1/10 or less, while linearity was dramatically improved to create a near-perfect sound that transcends the boundaries between digital and analog. Enjoy the sound of nature.

Luxman is taking their Z-Series integrated amplifiers to a performance peak! 

Luxman L-509Z Integrated Amplifier

Introducing Luxman's next-level “single-chassis separates” concept, pursuing the ideal with a new, all-in-one flagship amplifier. L-509Z is the premium model for the new Z-Series generation, the L-509Z has evolved beyond the concept of a traditional integrated amplifier. Both the preamplifier and power amplifier sections simultaneously use our new generation amplification feedback engine “LIFES” for the first time. The volume control is supported by our new “LECUA-EX” attenuator system that suppresses sound quality deterioration and realizes a more precise feel of operation. The “single-chassis separates” concept, which aims for the ultimate in integrated amplifiers, now achieves unprecedented performance. Pursuing the ideals of audio enthusiasm, we are combining our passion for music with improved technology. The L-509Z, a new pinnacle of LUXMAN integrated amplifier design.

Luxman's latest amplification feedback engine literally brings music to life with LIFES* Version 1.0

By feeding back only the distorted components generated in the audio signal’s journey to the final amp stage, LUXMAN’s proprietary “ODNF” amplification circuitry achieves excellent static characteristics and natural sound quality as if it were a “non-feedback” system. During the development of the M-10X flagship stereo power amplifier launched in 2021, technical concepts explored there were retained and the circuit configuration, which had become very complex over years of improvements has been completely redesigned to realize “LIFES” exquisite, high-fidelity sound and defines an amplification feedback engine blueprint for our next generation of components. The L-509Z is equipped with independent LIFES modules operating simultaneously in each of its fully discrete pre and power sections. The L-509Z is a pre-main amplifier that is worthy of the “single-chassis separates” concept that incorporates quality seperate units into a single, elegant chassis and has achieved an elevated level of musicality and unprecedented detail in comparison to other amplification circuits. The output section utilizes three stage Darlington bipolar transistors in quadruple-paralleled push-pull configuration to achieve outstanding output power and near perfect power linearity performance comparable to a standalone power amplifier, developing 120W+120W at 8 ohms and 220W+220W at 4 ohms.The result is spectacular sound quality with an abundance of energy.  *ODNF stands for “Only Distortion Negative Feedback” *LIFES stands for “Luxman Integrated Feedback Engine System”.

Electronically controlled attenuator LECUA-EX* incorporating an elaborate rotation mechanism

A tactile, satisfying volume control function is essential for audio amplifiers. To feed a fixed gain power amplifier with a musical signal at a level suitable for listening, precise control is required to smoothly attenuate the voltage while maintaining the quality of the input source. LECUA, developed by LUXMAN, is an electronically controlled attenuator system that switches through a series of high-quality, fixed value resistors for each channel independently. These are neatly arranged on the sub-assembly according to the position of the volume control knob. Since the release of the C-1000f control amplifier in 2006 to commemorate LUXMAN’s 80th anniversary, “LECUA1000”, which similarly integrates into the amplification circuitry, has been used in many LUXMAN products as a volume control system that minimizes the effects of external vibrations and changes in sound quality across the operating range of the volume control and is also resistant to deterioration over time. The L-509Z combines a highly precise rotary encoder with a newly developed weighted rotation mechanism to create the “LECUA-EX”, which offers even greater reliability and a natural, high-quality operational feel. 88 fine steps from 0 to 87dB and an acceleration setting for the speed at which the volume knob is rotated and a long-press setting for the remote control allow for comfortable and thorough volume control action with minimal degradation in sound quality.  *LECUA-EX stands for Luxman Electronically Controlled Ultimate Attenuator - Excellent eXperience

The L-509Z is equipped with LUXMAN’s traditional, highly stable power supply circuitry, featuring a bespoke, highly regulated 600VA El transformer and newly developed large-capacity filter capacitors (10,000μFx 8) .

The built-in high-quality phono equalizer circuit, which supports both MM and MC cartridges, features a new two-step gain switch to select between high and low MC settings to accommodate a wider range of MC cartridges, enriching quality vinyl playback in terms of both operation and sound quality. And a Mute-Button is now featured on the front panel.

In addition to BASS and TREBLE, a new MIDDLE control effective in the vocal and lead instrument frequencies bandwidth has been included. LR balance, line straight, loudness, and other functions are also conveniently at your fingertips.

Peel-coat circuit boards are used for the main audio signal path, eliminating the negative effects of the coating film that can adversely affect sound quality. Unique attention has been paid to every detail, such as the beeline construction, which configures circuits to take the shortest route possible, and a non-angled wiring pattern for smooth signal transmission.

Large, low resistance speaker relays are connected in parallel to transmit the driving force from the substantial power supply and output circuitry. Internal, 3.5mm2 ultra-thick cable is directly connected to the speaker terminals to ensure low impedance transmission, achieving a damping factor of 330 (current injection method).

The top panel is made of ultra-thick aluminum with an exquisite hairline finish. Large ventilation holes are carefully machined one by one to ensure efficient heat dissipation. Supporting the unit are four large insulator feet made from cast iron, their density gradient protecting the main chassis from unwanted external vibrations.

Large needle-movement VU level meter and 7-segment LED

Needle-movement type analog VU meters are traditional design statement, proudly characterizing LUXMAN’s solid state integrated amplifiers. The L-509Z is equipped with two large meters, brightly back-lit by LEDs, with sensitive response characteristics. The newly included 7-segment LED display in between the left and right level meters displays the current attenuation amount and is easily visible from the listening position.

In addition to the φ6.3mm standard terminal, a φ4.4mm terminal with independent left and right grounding has been added for pleasurable headphone enjoyment. Using balanced cable equipped headphones improves L-R separation and localization, surrounding the listener with gorgeous three-dimensional sound.

Original high regidity RCA terminals are used for LINE-1 and 2. Separate inputs and outputs for system expansion are provided with two pre-outputs. Two large speaker output terminals with independent on/off switching allow for bi-wire connectivity.

The substantial, ergonomic aluminum alloy remote control can also operate compatible LUXMAN CD players released after 1996.

Luxman L-505uXII - 2 Channel Integrated Amplifier

The attraction of the L-505uXII is its new level of refinement, approaching perfection as an authentically desirable product

The L-505uXII is the eagerly awaited Mark II version of the popular L-505uX that has been at the forefront of pre-amplifier design since it's launch in 2011. Incorporating an abundance of proprietary technologies, such as Luxman's Version 4.0 ODNF (Only Distortion Negative Feedback), as well as LECUA (Luxman Electronically Controlled Ultimate Attenuator), this product is a truly multifunctional integrated amplifier. As Luxman's latest high-end model, the L-505uXII continues the evolution of the L-505 series, which has attracted many fans of audio quality and earned a great reputation. As an amplifier which exudes sophistication and authenticity beyond its class, the L-505uXII represents the latest in a long line of exemplary models.

ODNF Version 4.0 - Innovative Amplification Feedback Circuit

An integral part of the design of the L-505uXII is LUXMAN's original ODNF amplification feedback circuit featuring a high-speed primary slew rate, an ultra-wide bandwidth and a low level of distortion that is achieved by feeding back only the distorted components of the audio from the amplifier's output circuit. The L-505uXII is equipped with the latest Version 4.0 ODNF circuit, resulting in a dramatically enhanced accuracy in distortion detection due to the paralleled first stage and Darlington equipped second stage amplification circuit, as well as a paralleled first stage error detection circuit. With it's lower impedance and higher S/N ratio, the L-505uXII realizes accurate reproduction of even the gentlest audio signals and achieves a full range of dynamic musical expression. The output stage, with it's parallel push-pull structure, has secured sufficient power at 100W+100W(8O) and 150W+150W(4O).

Highly Accurate LECUA Computerized Attenuator

LECUA (Luxman Electronically Controlled Ultimate Attenuator) is at the heart of the pre-amplifier section and the sound volume adjustment function of the L-505uXII. The L-505uXII design also uses a solid state(IC) type circuit to achieve a significant reduction in size. LECUA provides an ideal level control mechanism that allows smooth and fine volume adjustment over 88 steps, thereby minimizing any deterioration of the audio signal. In addition, left and right balance adjustment is integrated into the attenuator's control functions. The multifunctional ability of LECUA ensures accuracy over the full range of the volume control, whilst suppressing any deterioration of sound quality. The volume may also be adjusted with the remote control, but when adjusting the volume manually, the tactile design and gradual motion of the control itself enables intuitive adjustment of the attenuation level.

The L-505uXII features a new discrete buffer circuit in the output stage of the pre-amplifier circuit that is equivalent to the type used in our high-end C-900u separate amplifier. The pre-amp output stage is able to drive the signal with enhanced current supply capacity. The clarity of the audio signal is protected, whilst at the same time, the driving force fed through to the power amplifier stage is significantly increased. The power and reproduction capability of the L-505uXII achieves overwhelming scale sensitivity and a sharpness on start-up that cannot be achieved by conventional pre-amplifiers.

The power supply of the L-505uXII consists of an EI core type power transformer, highly regulated, with four large capacity 10,000µF blocking capacitors creating a highly stable power supply. This ensures an instantaneous, constant and stable current supply.

Large-capacity, low resistance speaker relays are connected in parallel to enable lossless transmission for the powerful driving force that is generated by the large-scale output circuit. In addition, the damping factor has been improved from 180 to 210 by lowering the impedance of the wiring pattern.

Original Technologies Prioritize Sound Quality

To realize a smooth, stress free signal transmission LUXMAN use an original Beeline construction that features a non-angled wiring pattern to allow smooth signal transmission along the shortest optimal route. This is one of many examples of a LUXMAN original design that makes sound quality a priority.

A Wide Variety of Custom-Made Components for High Sound Quality Components for High Sound Quality

OFC cabling is used in the internal wiring of the L-505uXII, achieving natural signal transmission due to the spirally wrapped shielding on each non-plated wire core. A high quality input selector IC is employed to improve separation and eliminate crosstalk. This model is generously equipped with many custom-made parts designed to achieve high sound quality such as in-line layout speaker terminals for easier speaker cable connection.

Luxman L-509X - 2 Channel Integrated Amplifier

The realisation of a desirable ideal the ultimate refinement of separates in a single unit.

The L-509X integrates the features of both a high quality separate amplifier and a high performance integrated amplifier into one product. The goal of creating an ideal integrated amplifier, initiated by LUXMAN with the launch of the L-509fSE in 2002, has now been advanced with the development of the L-509X. The L-509X integrated amplifier is equipped with many desirable features, such as the New LECUA1000 and a discretely configured buffer circuit in the output stage of the pre-amplifier circuit. LUXMAN’s ODNF (Only Distortion Negative Feedback) original amplifier feedback circuit and a power supply with independent left and right channel blocking capacitors are intrinsic to this design, as well as many components used only in high end models, ensuring high-quality audio reproduction. The design of the L-509X incorporates the cream of LUXMAN's proprietary technologies, breaking new ground and creating the ultimate expression of “separates in a single unit”.

An integral part of the design of the L-509X is LUXMAN's original ODNF* amplification feedback circuit, featuring a high-speed primary slew rate, an ultra-wide bandwidth and a low level of distortion that is achieved by feeding back only the distorted components of the audio signal from the output of the amplification circuit. The L-509X is equipped with the latest Version 4.0 ODNF providing a dramatic enhancement of accuracy in distortion detection due to the triple-paralleled first stage error detection circuit. Lower impedance and a higher signal to noise ratio have been achieved due to the paralleled first stage and Darlington equipped second stage amplification circuit. A 3-stage Darlington circuit and a 4-parallel push-pull structure is used for the output stage, similar to the M-700u power amplifier. This achieves output at 120W+120W(8O) and 220W+220W(4O), enabling the L-509X to drive speakers powerfully with rich dynamics and full expression.

ODNF stands for “Only Distortion Negative Feedback”.

This generous custom specification ensures that the power supply unit will not be affected by any load fluctuation.

The L-509X is equipped with a discrete buffer circuit that is equivalent to the type used in the high-end LUXMAN C-900u separate amplifier. The clarity of the audio signal is preserved by this circuit whilst at the same time the following power amplification stage's driving force is significantly increased.

The use of crack-resistant peel coat PCBs for the amplifier boards prevent the quality of audio signals being adversely affected. This product prioritizes audio quality in features such as the non-angled, direct wiring pattern, known as the original LUXMAN’s Beeline construction, ensuring smooth signal transmission via the optimum shortest route.

Large-capacity, low resistance speaker relays are connected in parallel, enabling loss-less transmission of the powerful driving force that is generated by the generous power supply circuit and the amplifier output section of the L-509X. The use of 3.5mm2 cabling for the amplifier board output and the unit's damping factor of 370 enables the L-509X to drive all kinds of speakers accurately.

LUXMAN's New LECUA1000 is at the heart of the preamp section and the volume adjustment control of the L-509X. This computerized attenuator is integrated with the amplification circuit, a feature integral to the high-end LUXMAN C-900u control amplifier. LECUA provides an ideal level control system which allows smooth and fine adjustment of the volume over 88 steps, thereby minimising the deterioration of audio quality at any point of the volume adjustment range. An advancement of the New LECUA1000 is the 3D design layout. The attenuator circuit board is directly connected to the amplification circuit board. Signal routing has been minimized andefficiency has been successfully enhanced. In addition, this design is extremely resistant to external vibration and eliminates changes in audio quality over the volume control range. The robust nature of this system ensures longevity and durability.

A rated output of 20W +20W (8O) of pure class A amplification achieves a mellow, expressive sound with a heightened sense of density with high drivability to speaker systems.

ODNF stands for "Only Distortion Negative Feedback".

A high-inertia power supply circuit that combines a large capacity EI core type power transformer (to which a vibration control feature has been newly added) and a large capacitor block (10,000uF x4) is an integral part of the L-550AXII. This large capacity power supply circuit supports the sound dynamics of the unit by enhancing stability at the core of the design.

A discrete buffer circuit that is the equivalent to those used in the top end LUXMAN C-900u separate amplifier is mounted on the output stage of the pre-amplifier circuit. This protects the purity of the audio signals whilst simultaneously enhancing the drive force for the power amplifier.

The large capacity, low resistance speaker relays are connected in parallel in order to transmit the powerful drive force that is generated by the high inertia power supply circuit and the large scale output circuit without loss. Connecting directly to the speaker terminals in this way significantly improves the damping factor from 160 to 200.

The L-550AXII is designed using proprietary technology and customised parts to optimise the sound quality of this integrated amplifier. For example, the round pattern board enabling smooth signal transmission, and a Beeline construction configuring the optimal parts locations and the shortest signal routes. In addition to this, the loopless chassis structure minimizes the ground impedance increase.

Customised Parts Making Sound Quality the Priority

Original LUXMAN OFC wires are used in the internal wiring of the L-550AXII achieving a smooth signal transmission due to the spiral wrap shielding on each core and the non-plating process on the core wire.

Providing an exceptionally deep resonance of sound sources of various ages and genres, the LX-380 combines LECUA* - a computerized attenuator which carefully reproduces the dynamism of each performance - with a power amplifier circuit that expresses the rich musicality of the 6L6GC output tube. Housed in a wooden case that is reminiscent of the 28 series, the LX-380 appeals to a new generation with a winning combination of cutting edge technology and traditional know-how. *LECUA is an abbreviation of Luxman Electric Controlled Ultimate Attenuator.

The LX-380 is equipped with the 6L6GC beam power tube that has a reputation for high quality, stability and a delicate, soft tonal quality. The rated output of 20W+20W that is sufficient for a domestic sound system is achieved through the combination of a powerful, flexible Mullard type driver stage with a push pull structure final stage. This adopts a fixed bias type to maintain a constant grid voltage. The auditory drive force that is created by a vacuum tube amplifier is not easily quantified. This and a dense, mellow tonal quality have been achieved comfortably in the design of the LX-380 not with a high-power specification but by building in a margin in the vacuum tube and peripherals. The combination of experience and original design knowledge results in longevity of enjoyment of this product with long term peace of mind.

The elegant exterior in a natural veneer finish in a full sized (440mm) square wooden case is reminiscent of the original classic layout that consists of a combination of knob and lever switches made of machined aluminium and resin.

The First Ever Vacuum Tube Amplifier to Feature LECUA

The LX-380 is the first vacuum tube amplifier to feature LECUA, the proprietary computerized control attenuator from LUXMAN that enables the sound to be adjusted smoothly with minimal deterioration using an 88-step method. The LX-380 uses the same high sound quality semiconductor circuit that has been successfully proven in integrated amplifiers such as the L-590AX.

The LX-380 is equipped with an electronically controlled tone control function (bass/treble) for delicate adjustments to the tonal quality per the sound source and listening environment, with 3 selectable turnover frequency positions. The loudness mode interlocks with the sound volume to enable the correction of bass and treble ranges depending on human hearing characteristics.

Due to their profound sound quality, analog records are now becoming popular again and the LX-380 is therefore equipped with a high sound quality semiconductor structured phono amplifier circuit that is compatible with MM/MC types. This circuit derives from the concept of the LUXMAN integrated amplifier and allows users to enjoy genuine analog record playback without adding an extra dedicated phono amplifier. A subsonic switch is provided on the front panel to suppress any woofer fluctuation that is caused by low frequency signals from warped records as well as a monaural switch to activate L channel or R channel with the same signal at monaural record playback. Such detailed design and functionality enable the full enjoyment of analog playback.
