Luxman-509X

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”.ODNF* Version 4.0 - innovative amplification feedback circuitAn 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(8Ω) and 220W+220W(4Ω), enabling the L-509X to drive speakers powerfully with rich dynamics and full expression. *ODNF stands for “Only Distortion Negative Feedback”.Chassis structure exemplifies excellence in function and designThe L-509X features a top panel with a beautiful hair-line finish and widened venting to improve heat dissipation. The loop-less chassis structure restricts any increase in ground impedance. Analog level meters, illuminated with white LEDs, add to the elegant and stylish appearance. New LECUA*1000 computerized attenuatorLUXMAN'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. *LECUA stands for “Luxman Electronically Controlled Ultimate Attenuator” Spec Rated output    120W + 120W (8Ω), 220W + 220W (4Ω) Input sensitivity/input impedance    PHONO (MM): 2.5mV/47kΩ PHONO (MC): 0.3mV/100Ω LINE: 180mV/47kΩ BAL.LINE: 180mV/55kΩ MAIN-IN: 1.1V/47kΩ Output voltage    REC OUT: 180mV, PRE-OUT: 1V Frequency response    PHONO: 20Hz to 20kHz (±0.5dB) LINE: 20Hz to 100kHz (within -3dB) Total harmonic distortion    0.007% or less (8Ω, 1kHz) 0.06% or less (8Ω, 20Hz to 20kHz) S/N ratio (IHF-A)    PHONO (MM): 91dB or more PHONO (MC): 75dB or more LINE: 105dB or more Volume adjustment    New LECUA1000 Amplification circuit    ODNF 4.0 Output configuration    Bipolar 4-parallel push-pull Damping factor    370 Max. amount of tone control    BASS: ±8dB at 100Hz TREBLE: ±8dB at 10kHz Power supply    230V~(50Hz) /115V~(60Hz) Power consumption    380W 150W (under no signal), 0.5W (at standby) External dimensions    440(W) x 193(H) x 463(D) mm front side knob of 20mm and rear side terminal of 37mm included in depth Net weight    29.3kg (main unit) Accessories    Remote control (RA-17A) Power cable Speaker terminal Supported Y-lug terminal dimension    Width of part a: 16mm or less Width of part b: 7mm or more * Connection may not be performed depending on the shape of the Y-lug terminal.

Technics SU-R1000E-S

JENO Engine Jitter is a major cause of distortion in digital systems, and is caused by mis-timing in the master clocks used in digital-to-analogue conversion. To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and re-quantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These technologies enable Technics digital amplifier designs to reproduce the natural and delicate nuances of music. ADCT (Active Distortion Cancelling Technology) The Active Distortion Cancelling Technology newly developed by Technics accurately extracts and removes distortion in the power output stage which is generated by the speaker’s counter electromotive force and voltage drops. In the Hi-Fi audio market where an unlimited number of audio systems can be configured by combining various products, high-end audio amplifiers need to optimally drive a diversity of speakers. The Active Distortion Cancelling Technology accurately extracts distortion by determining the difference between the speaker terminal output and JENO output and then applies correction to the output digital signal, thus correcting the conventional digital amp system. This provides powerful speaker driving force and acoustic energy while offering the superior benefits of a digital amplifier, such as low noise, precise sound image and expansive sound ambience, regardless of the types of connected speakers. Advanced Speed Silent Power Supply The SU-R1000 uses a switching power supply system to ensure a stable supply of voltage and current required by the digital amp. In a conventional switching power supply system, the ON time of the switching operation was controlled in order to stabilise the voltage, and this causes the switching frequency to fluctuate according to the load, resulting in a modulation noise to affect the sound quality. The Advanced Speed Silent Power Supply has eliminated this noise by fixing the switching frequency in the 400kHz band. Furthermore, a Super Low Noise Regulator is provided in the later stage. This prevents the decrease of regulation resulting from the fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a high-response power supply that results in the best performance from the digital amplifier. Four Independent Power Supply Units In the SU-R1000, every element comprising the power supply has been diligently studied and revised for higher sound quality. What’s more, four independent power supply units are provided for different circuit blocks for further enhancement of sound quality. Since the SU-R1000 is an integrated amplifier, the internal circuits consist of a pre-amp stage and power amp stage in a mix of analogue and digital circuits. The Phono-EQ section which processes minute analogue signals is particularly susceptible to the effect of noise transmitted through the power supply line. The SU-R1000 uses separate power supply units for the analogue circuits and digital circuits in the pre-amp stage. It also uses separate power supply units for the right and left channels in the power amp stage that requires large electrical power. With the four independent power supply units, the SU-R1000 prevents power-line-induced interference among the circuit blocks and realises a high S/N ratio and superb separation. High-grade Digital/Analog I/O Circuit The phono input section and analogue input section feature a full-discrete circuit design. Technics has realised an ideal, symmetrical circuit layout and performed meticulous tuning. The new circuits prevent interference between the right and left channels and achieve excellent channel separation. Furthermore, the phono input section and XLR input section employ completely balanced transmission to ensure high-purity signal transmission with minimum effect of noise. The USB input circuit in the digital input section is equipped with a capacitor of high-quality ruby mica and a power conditioner with nonmagnetic carbon film resistors for blocking electrical noise e.g. from a PC and for minimising the effect of external noise. The A/D converter incorporates a high-performance chip made by Asahi Kasei Microdevices (AKM) for high-precision A/D conversion. Thus, the SU-R1000 reproduces outstanding sound quality from any analogue or digital input sources. High Rigidity Chassis and Design The rigidity of the chassis has been enhanced extensively to suppress the enclosure vibration that is also a source of noise. The inner chassis features a double-deck separated structure. Mounted on the upper deck is the power amp section consisting of the amplification circuit and its power supply circuit. Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates.They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels. Input and output terminals made of meticulously selected high-quality parts - Speaker terminals designed to allow connection of extra-large diameter speaker cables - Y-lug terminals for ensuring reliable cable connection - Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC) - Analogue input terminals with gold-plated, machined brass parts Technics’ refined design - Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter - Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finished Intelligent Phono EQ The Intelligent Phono EQ mounted in the SU-R1000 utilises the sound quality improvement technology for DSP, which Technics has accumulated through the development of LAPC, in order to realise high sound quality not possible with analogue Phono-EQ. This technology consists of three parts: 1. Accurate EQ Curve, 2. Crosstalk Canceller and 3. Response Optimiser. These functions can be turned ON/OFF to suit the user’s preference. Accurate EQ Curve – Made possible by hybrid analogue/digital circuit design An accurate EQ curve is achieved by a hybrid analogue-digital system. The high-gain low-pass filter (LPF) performs analogue processing, while high frequencies are raised after the A/D conversion. The use of the 40-dB LPF(Low-pass filter) in the analogue region suppresses the bit loss during digital filter processing, and high frequencies are raised with high accuracy in the digital region to achieve a high S/N ratio. Crosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridge This function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000. It then performs reverse-correction using the built-in DSP to achieve significant improvement of the crosstalk characteristic. This results in a more precise sound image and a wider sound ambience. Phono Response Optimiser - For correction of disturbance in cartridge frequency characteristics This function measures the frequency characteristics of the installed pickup cartridge by using a TSP (Time Stretched Pulse) signal recorded on the bundled Calibration Record, and corrects characteristics disturbance. It corrects the effect of impedance matching between the pickup cartridge and the phono equaliser to reveal the true sound quality of the cartridge. This technology aims to improve sound quality by avoiding a selector such as a switch in the high-sensitivity phono input line for the removal of the possibility of noise disturbance. *Although the record may be warped depending on the production method or its characteristics, this record passed the test for proper signal reading and is shipped. *The record may be warped depending on the storage environment in your house. Please note a badly warped record may not only disturb the measurement but also hurt the cartridge.

Musical Fidelity M8xi Silver

In 1990, Musical Fidelity made the first-ever Super Integrated amplifier: the A1000. lt received a rapturous welcome and, even today, second hand, is selling at high prices. The A1000 was the first of a long line of Super Integrated Amplifiers from Musical Fidelity. Its children: the NuVista M3, Tri Vista 300, kW500, M6/500i, NuVista 800 and NuVista 600 all were equally enthusiastically welcomed to the audiophile world. The M8xi is the latest and the best of the breed. General Description The M8xi is a separate preamp with two monobloc power amps sharing a common chassis. Each has its own heat sink and separate transformer. Genuinely dual mono. The preamp has its own separate power supply and is mounted close to the input sockets. Consequently, PCB tracks are very short. This elegant idea ensures that both channels' signals are ultra-low impedance the instant they get into the amplifier. This is a significant detail. Each channel has twelve big bipolar transistors - 200 amps peak to peak is easily available. The metalwork is high quality. The front panel is a custom made fine line extrusion of milspec aluminum. The custom made heat sinks have outstanding dissipation characteristics and finish. The M8xi construction has a feeling of solidity and quality. New Circuitry Over the last 5 years our power amp circuitry has reached a high state of development. In our never-ending quest for improving performance and customer value we have been looking for ways to improve our designs. One of the prime directives was to keep the low feedback configuration unchanged .. continue with low feedback! The problem was how to improve efficiency and performance without affecting the sound quality. If I say so myself, I think we have come up with a brilliant solution. Our new M8xi power amp design gives higher power, lower distortion, and better sound quality. Incredible but true. The output stage efficiency has been increased thus yielding about 10% more power for similar power supply voltage. More importantly, the whole driver stage is pure Class A. We believe that this innovative approach has a substantial effect on the sound quality. The sound stage appears wider whilst the micro and macro dynamics have more impact. This effect is particularly noticeable on well-recorded piano. I am sure you all know the piano is a percussive instrument but in truth, this is rarely audible on most Hi-Fi systems. Using an M8xi a piano‘s percussive nature becomes instantly obvious and jumps out of the loudspeaker. lt is a surprising and satisfying improvement to the sound quality. Vocals have more subtly, detail and presence. Large scale music has depth, width, and incredibly dynamic presentation. All in all the M8xi is a consummate all-rounder. Mostly it sounds like a small Class A amplifier with huge power. The DAC The M8xi also features a 5 input DAC. DACs are increasingly common in integrated amplifier designs to add convenience when connecting a variety of digital sources, so the decision was taken to build-in a DAC that would perform to a high standard, independently of the amplifier. For added integrity, the DAC features its own power supply. Based around the Texas Instruments PCM5242 TI low-distortion and low-noise DAC chip, which is also employed in many other premium products in the hi-fi industry as well as in previous Musical Fidelity products, the M8xi has 2 x coaxial (S/PDIF), 2 x optical (S/PDIF) and 1 x asynchronous USB Type-B inputs. The coaxial and the USB inputs are capable of supporting hi-res audio streams up-to 24-bit / 192kHz, and the optical input is capable of supporting up-to 24-bit / 96kHz. For maximal performance, all data streams are up-sampled and re-clocked by an internal converter to reduce jitter and remove unwanted artifacts in the sound. Technical Performance The M8xi delivers 550 + 550wpc into 8 ohms. It is extremely stable and very linear. The distortion is low too; lower than 0.005% in the audible frequency range of 20 Hz to 20 kHz. The M8xi has remarkable linearity and consistency. lt is unconditionally stable and will drive any loudspeaker in existence easily with ample power reserve. Our Approach to Technical Measurements In our view an amplifier should be completely neutral. lt is ‚a straight wire with gain‘. Easy to say but hard and complex to do. We want to stress that we do not believe that the technical performance is an end in itself. lt is a method of validating the total amplifier system concept. The aim of our circuit/PCB designs is to have low feedback and achieve complete neutrality, transparency, and great technical performance. The proof that we are on the right track is the technical performance. We think that technical performance cannot be summed up by the distortion at 1 kHz. Our view is that an amplifier has to be able to satisfy a wide range of technical requirements before it can be neutral. Linearity Almost all loudspeakers have complex impedance and loading curves. An amplifier must be able to maintain its voltage virtually, regardless of loading. If an amplifier cannot maintain its voltage across the spectrum, then the ultimate frequency response and distortion will be nonlinear. This is not neutrality. Distortion The overwhelming majority of amplifier manufacturers only talk about distortion at 1 kHz. We believe that this is only a fraction of the story. From our perspective, an amplifier must have very low distortion from 20 Hz- 20 kHz and beyond. We believe that an amplifier‘s high-frequency performance proves the total performance of the circuit and PCB layout. The M8xi distortion hardly changes from 10 kHz to 50 kHz. An outstanding achievement and validation of the circuit design and PCB layout. Noise Ratio Amplifiers should be quiet. If they are not, low-level detail is irretrievably lost. Also, the dynamic range is seriously compromised. Dynamic range is not just how much power an amplifier will produce, it is also how quiet it can be. Dynamic range is the total from the quietest to the loudest. The M8xi excels in this respect. Precision Volume Control The M8xi has a precision volume control. This ensures perfect tracking right down to very low levels which is unattainable with standard potentiometers. This outstanding precision is achieved by laser-trimmed substrate resistors. Sound Quality The M8xi is effortless, fluid, and dynamic. lt doesn‘t sound ‚loud‘. lt just sounds right. The dynamics are handled with no drama or fuss. They come and they go. There is no distortion; just pure undiluted music. lt sounds like a superb small Class A amplifier but with limitless headroom. Perfection!
