Pathos Classic One MKIII

After having won over the international audiophile community with state-of-the-art reference amplifiers, to conceive a product with a set price point as the main design limit has been a true challenge to Pathos.
The Classic One project was initiated to transfer, in a more affordable amplifier, all the know-how and expertise acquired developing reference products.
Classic One represents a new standard in its price category: it success fully blends in a single chassis a preamplifier and power amplifier, completely separated from each other and provided with their own individual power supplies.
The pre-stage – or, better, the pre-amplifier – is purely tube, balanced, pure Class A, extremely low noise, with high intrinsic linearity and without any feedback. It provides an exquisitely tube sound in terms of transparency, air, harmonics and refinement… in one word, musicality.
The power stage is a solid state power amplifier, high bias current, Class A/AB in order to adequately drive every load. It provides the sound with speed and dynamics, without influencing the tube nature of the sound. The volume control is motorized and remote controlled, the remote itself is in solid wood. Power supplies are over-dimensioned and stabilized. Selected components, pure silver Pathos signal cable wiring, gold plated terminals, high quality materials and refinement at its highest standard are additional benefits provided with the Classic One.

Together with such sound performance and overall quality, the Classic One is offered at a price that clearly demonstrates a philosophy of value for money. This is possible thanks to an aimed design approach, coupled with extremely accurate engineering and superior aesthetic form.

The H590 includes user friendly services such as Apple AirPlay®, while at the same time embracing ultra high performance formats like DSD. With SoundEngine 2 technology and Hegel’s finest amplifier implementation to date, the H590 really personifies our strive to bring High End to the people. The H590 uses the patented SoundEngine2 technology combined with a very high power, low distortion amplifier design. The result is unmatched dynamic capabilities while still maintaining a smooth, natural sound with all the details of the music. You will experience a huge soundstage and only want to turn the volume up, up, up and up.

The H590 is a reference amplifier throughout. From the carefully designed balanced and unbalanced inputs, with hand matched transistor pairs, ensuring minimal distortion to the delicate signal from an analog source such as a phono stage. Via the pre-amplifier, with its dedicated high quality power supplies and a unique volume control, to the massive output stage where you will find 12 ultra-fast high power output transistors… per channel. The H590 is a beast. Many people nowadays use digital music as their main source of listening, so great care has been put into the DA-Converter, where all signals will be kept in their original form throughout. If you play high resolution or CD-format, they will all be played in their native form for best sound quality. Via the USB input, the H590 will also support high end formats like DSD. The H590 includes MQA decoding and rendering technology, which enables you to play back MQA audio files and streams, delivering you the sound of the original master recording.

The H590 is also a dream for people who are into streaming. First of all, there is Upnp streaming and second there is Hegel’s proprietary implementation of AirPlay. That means Apple Airplay user friendliness combined with the high performance Hegel sound. It does not stop there though, as the H590 is also software upgradable, and additional functionality will become available in the future. If you live in a smart home, the H590 can be a natural part of that too. With services like Control4 built in, and 2-way IP control for other smart home control systems, using the H590 can be as easy as switching on the lights. In short, while many high performance audio systems are made “only” for the enthusiast himself, the H590 is designed to give joy to the entire family.

There is ease of use and there is security. Afraid that the kids will play too loud when you are away from home? No problem. Simply set a desired maximum volume level and lock it there. The H590 can even be used to provide better sound in your Home Theater, or to combine a Theater and a system for music listening. Do you enjoy your Sonos or Bluesound app and want to use those, but without losing the sound performance of the H590? No problem. Connect them, lock the volume on the input and you are in full control using only the Sonos app (example).

Hegel P30 Reference PreAmplifier

Hegel P30The P30 is the best preamplifier ever developed by Hegel. With its patented technology and hand matched components, the P30 is a confident contender in the race towards being the best pre amplifier in the world. Regardless of price. Despite of what many Hi-Fi enthusiasts believe, preamplifiers are actually one of the most difficult audio components to develop. At the same time it is one of the most important components in a well sounding system. The reason is that the signal strength is very low when entering the preamplifier, and is therefore very susceptible high frequency noise and distortion elements. The most critical phase in the preamplifier is the volume regulation, and in the P30 this is a master piece in it self. The physical volume control knob is only used to describe the desired volume output level to the array of Gigahertz MOS-transistors. These direct the music signal through a network of high quality resistors that reduce the signal level.

Hegel H30 Reference Amplifier

Hegel H30With a power rating of more than 1,1 kW in 8 ohms it is on the verge of being easier to measure the H30 in horsepower. The massive H30 mono power amplifiers from Hegel play any loudspeaker in the world with ease and authority. The H30 is our best power amplifier ever, and is definitely a combatant for being the best power amplifier in the world. The H30 is developed as a mono block, but there is also the possibility to use it as a stereo power amplifier to start with if you are on a budget. Progress is a one way street and so for our power amplifiers. The H30 is using a new and improved version of the patented Hegel SoundEngine amplifier technology. This further reduce all types of distortion. In addition to the improve SoundEngine we are also using the highest possible level of the Hegel FET-technology in the input stage and the voltage gain stage. This technology reduce a very specific type of distortion called Harmonic Distortion. This particular type of distortion causes what many people call “transistor sound”, and this is therefore dramatically reduced in the H30. It will simply let the music reach you in a different way than what you have ever experienced before.

Luxman L-550Ax, Pure Class A, Integrated Amplifier

L550AX_front_smallLuxman produced the world’s first Class A integrated amplifier in 1981 – L-550.

Luxman introduced the L-550Ax and L-590Ax in 2005, since then we have celebrated our 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. For example, the amplifiers feature a new electronic selector switch, adopted from the input section of the C-1000f control amplifier; the internal circuitry has been revised to include customized OFC wiring and a high-speed Schottky barrier diode has been selected for the power source section; improvements that have notably enhanced the sound quality for greater musical enjoyment.

Chassis bases have superb vibration absorption in order to suppress noise levels. The power transformer, electrolytic capacitors and amplifier output stage (see amp block below) are laid out so as not to interfere 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, amongst 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 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.

 

Both the L-590AII and L-550AII, 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 previous 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.

Luxman Control Amplifier C800f

c800fWe have acquired a great number of technologies for improvement of sound quality through the development of our flagship model, C-1000f. Such technologies have been integrated into newly appeared C-800f, a masterpiece of control amplifier. Our original feedback circuit, ODNF, is introduced into C-800f, which is version 2.4 as the same as used in C-1000f. In the attenuator section that is integrated into the amplification circuit, 4 pieces of “LECUA1000-WM” that has been newly developed for improved efficiency with the signal path are mounted. Various gorgeous specifications are inherited from our flagship model including full-balanced transmission circuit, power supply equipped with current supply source comparable to a power amplifier, and bi-amplification output mode. C-800f can fully exercises its unlimited dynamism and richness of music essence when a high-performance power amplifier such as M-800A is driven.

Luxman M800 Pure Class A Amplifier

m800Luxman’s emphasis is on reproducing natural music, with lots of warmth, detail; not frightening it into scaring up non-existent detail, which is sometimes described as etched. Luxman’s engineer’s are fanatical in their attention to detail; while they spend a lot of time analyzing how components perform on their test equipment, the final arbiter is the listening evaluations. Is the product able to play music, convey the emotion, reproduce the ambience of the venue as well as the timbre of each instrument, distinctly. This is where Luxman shines.

Beneath the elegant shell of a Luxman amplifier, lies innovative circuitry, meticulous attention to detail and plain common sense.

Using trickle down technology from the flagship B-1000f, comes this stereo Class A power-house amplifier, with pure A 60W x 2 per channel, into 8Ω. It is stable driving any loudspeaker, even 1Ω loads, with 480 watts to spare.

Modulus 3B Full-Function Valve Line Stage

OLYMPUS DIGITAL CAMERAIn 1981 Audible Illusions began production of the first Modulus preamplifier. Almost instantly, it became known as a breakthrough component setting new standards for sonic performance and reliability. Four years later, Audible Illusions introduced the Modulus 2 which carried the promise even further, quickly becoming one of the best-selling tube preamplifiers ever made. With the introduction of the Modulus 3 in 1992 the M3A in 1995 and the Modulus 3B in 2008 our Modulus preamplifiers have continued to earn a reputation for sonic excellence, construction quality and reliability.

To date over 20,000 Modulus preamps have been manufactured with over 150 excellent product reviews from audio critics around the world.

Adhering to our circuit design philosophy that “Simple is Better” and based on the proven superiority of single-ended, triode-tube designs our engineers continue to refine the preamplifier. Some of our innovations include the elimination of cathode followers, buffers, and negative feedback. The Modulus was also the first preamplifier to parallel tube output stages, and to design high performance Teflon capacitors. These are but a few innovations that have made our company a pioneer in modern-day tube technology.

The M3B is the natural evolution of the M3A. It remains one of the few full-function preamplifiers made and is built for vinyl and digital enthusiasts alike. Our goal was to retain the sonic signature of our previous design while improving on fundamentals that simply, let the music flow. The result is a preamplifier with a further simplified the signal path, improved switching, and reduced vibration. These improvements are elegant and results great sonic benefits.

The M3B is the finest full-function preamplifier we have ever made and continues to be the benchmark by which many others are compared.

Nagra BPS Solid State Battery Phono Stage

bps4The reduced size of the Nagra BPS phono preamplifier is the immediate result of using completely solid-state technology, less costly to implement than for the valve version.

The BPS electronics consumes so little that it operates on a single 9-volt battery with a life expectancy of about 100 hours. It is thus possible to renounce the usual Nagra very-low-noise external power supply that is complex and expensive to manufacture.
The Nagra BPS enjoys an attractive positioning thanks to a simplified approach as regards functions. Nagra however retained the popular load adaptation found on the VPS model, which allows to obtain, with small plug-in modules, the desired matching between the phono preamp and the specific cartridge used on the turntable arm.
The equipment supports either moving-coils (MC) or moving-magnet cartridges (MM) by means of appropriate switching.

Assembled on a single motherboard, the electronics use exclusively discrete and military-type components (JAN standard). The amplification is provided by selected and matched bipolar transistors. The capacitors on the signal path are of audiophile quality and the precision resistors are MELF (Metal Electrode Leadless Face). Versatile, simple and easy to use, it is intended to work with the best modern turntable units.

Quad Classic – Electronics

quadbanThe history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with the Quad 1 amplifier which brought the benefits of 15 years and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of it’s age.

A few years later, the product which set the standard for amplifiers was the Quad II Power Amplifier that was introduced in 1953, the year of Queen Elizabeth’s Coronation and the year in which Mount Everest was finally conquered. This amplifier pioneered the principal of cathode coupling through the output transformer to reduce harmonic distortion to almost negligible levels. Such was it’s clear superiority that this model remained in production for 18 years.

Three years later in 1956, Quad demonstrated the first true full-range electrostatic speaker. This remarkable product (know later as the ESL-57) used a virtually mass-less plastic film as a moving diaphragm between two charged plates. Compared to the loudspeakers of the time, the ESL free of unwanted colourations and distortions. This landmark product remained in production, virtually unchanged, for 28 years.
