What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

MASH multi-stage noise shaping

Technics' Innovative MASH 1-bit Digital-to-Analog Conventer.

To achieve ideal digital-to-analog conversion, Technics develloped the MASH 1-bit DAC. An improvement on conventional DAC's this advanced system uses high-order oversampling technology and noise shaping technology to theoretically eliminate non-linear distortion, thereby assuring accurate reproduction of minute signals.

All of Technics Cd players feature the MASH 1-bit DAC, and it is now the most widely used digital-to-analog conventer. 1-bit DAC is the general term for D/A conventers that output only two kinds of voltage, high and low . Because there are only two output voltages, even if there are changes in output voltage due to temperature changes and changes over time, DAC linearity is maintained.

TAD CR-1


With the flagship TAD Reference One TAD gained the whole-hearted trust and respect of many of the world’s top artists and recording engineers. As the ultimate realization of the point-source sound concept, it was created by merging advanced technologies with our decades of engineering experience. Now we have reached a new zenith with the TAD Compact Reference, which takes advantage of all of the top-level technologies that went into the flagship model.
Our objective was to achieve, in a compact size, point-source sound of such high quality that listeners will forget about the existence of the speaker. Its extraordinary sound will surely exceed your expectations.
"The CR-1 is the stand-mount sibling to the $70,000 320-pound TAD Reference One. Smaller yes, but it takes a dry sense of humor to characterize the CR-1 as a compact. At a thick 25" tall (it looks taller) and weighing in at hernia-threatening 100 pounds (it feels heavier), the CR-1 is anything but the kind of compact suitable for a meter bridge in a home recording studio. Rather its resemblance—both external and internal—to the Ref One is so complete that, except for the stands, it appears almost like an optical illusion of the flagship."


The refined CST Driver achieves wide-range reproduction and superior directivity control.
The CST (Coherent Source Transducer) is an advanced coaxial speaker designed to control the drive unit’s response and directivity over a wide frequency range. A design based on detailed simulations gives the midrange cone superior acoustic characteristics.
The concentric configuration controls the directivity of the tweeter to match the midrange. This unifies the acoustic center of the tweeter and midrange, reconciling response and directional characteristics through the crossover range. The resulting ultra wide range reproduction from 250Hz to 100kHz is accompanied by a consistent directivity pattern that results in extremely clear and stable imaging over a wide frequency range, for incredibly natural sounding reproduction.


The beryllium diaphragm: using TAD’s vapor deposition technique achieves the ideal characteristics.
The tweeter dome and midrange cone are constructed of beryllium, whose light weight and rigid properties make it perfectly suited for mid and high frequency sound reproduction. The vapor deposition technique developed by TAD and refined over three decades provides strength, uniformity and damping to achieve a new level of quality in a diaphragm. The shape of the tweeter is optimized through a computer analysis process known as HSDOM (Harmonized Synthetic Diaphragm Optimum Method), ensuring control of differential vibration and response to as high as 100kHz. The design of the midrange cone was derived from boundary and finite-element analysis to be the ideal partner for the tweeter and provide sound that is astonishingly transparent, direct and precise across a wide frequency range.


ISO drive technology draws out the full potential of the CST Driver.
In order to maximize the performance of the CST Driver and preserve accurate sound reproduction, TAD’s ISO (isolation) technology includes a mechanism to prevent driver unit vibration from entering the enclosure by structurally separating the CST Driver from the enclosure. Thanks to this unique construction the CST driver is isolated from powerful low frequency vibrations and its considerable drive capability is
prevented from exciting the enclosure. This reduces the radiation of secondary sound allowing for minute details in the sound to be precisely delivered.



Low loss, high linearity and a powerful motor system.
The 20cm (8.0 in.) bass driver reproduces waveforms with consistent accuracy.
The bass driver was designed to achieve total linearity of the magnetic circuit, diaphragm and suspension. The magnetic circuit features our unique short voice coil OFGMS (Optimized Field Geometry Magnet Structure). With a long gap of 20mm (0.8 in.), it linearizes the magnetic flux density along the gap. This stabilizes drive performance from small to large amplitudes, achieving high linearity and consistently accurate waveform reproduction. The TLCC (Tri-Laminate Composite Cone) aramid diaphragm has a triple-laminated construction that provides near ideal physical properties. It delivers rich and clear low-bass with a mid-bass free of coloration. The suspension system employs TAD’s traditional corrugated edge, further contributing to the high linearity.


SILENT cabinet combines extreme strength with gracefully flowing elegance.

The SILENT (Structurally Inert Laminated Enclosure Technology) cabinet, inherited from the TAD Reference One, is a compact 63cm (25 in.) in height. It has a strong internal framework formed by 21mm (0.9 in.) thick CNC machined birch plywood clad with high frequency hot press formed laminated MDF panels, resulting in extremely high strength. The 27.5mm (1.1 in.) thick aluminum base lowers the center of gravity and stabilizes the cabinet against the forces generated by the powerful bass driver motor system. Combining differing materials in this way both distributes and minimizes the enclosure resonances and achieves high vibration control. Its flowing teardrop shape minimizes sound diffraction and unwanted resonance from internal standing waves.
With a beautiful piano-like finish of natural Pommele Sapele wood, the cabinet imparts an air of elegant craftsmanship.


Aerodynamic port system employs TAD horn fluid design technology.
In order to make the most of the linear performance of the 20cm (8.0 in.) bass driver and its suspension, the bass reflex port is aerodynamically optimized based on precise fluid design technology refined by TAD professionals. This flare-shaped port produces absolutely no air noise or rectification effects, even when the bass driver unit is driven at the limit of its excursion range, achieving deep, clear bass.



The TAD Compact Reference employs strictly selected materials and parts, many inherited from the TAD Reference One
- Isolated bass, midrange and treble crossover networks eliminate electrical and magnetic interactions.
- Rear terminal panel is made of 27mm (1 in.) thick aluminum to act as a heat sink for the network.
- Custom-made parts include air-core coils, non-inductive resistors and PP film capacitors.
- Large custom-machined speaker terminals have thick gold plating to ensure reliable connections.
- All wiring is carefully routed away from magnetic parts to prevent degradation of sound quality due to magnetic distortion.
- Not only the speaker system itself, but also the drive units are subject to strict quality control based on serial numbers.

CDM 1SE

Stand - mount/Bookshelf loudspeaker system


Braced cabinet construction dramatically reduces cabinet resonance by adding the twin

virtues of strength and rigidity to the cabinet walls. Gold-plated terminals permit bi-wiring

or bi-amplification.

Having the tweeter separate from the main cabinet readily allows it to be set back and

time aligned with the acoustic centre of the bass/midrange cone, which is located behind

the plane of the front baffle, and minimises the effects of diffraction from the cabinet edges.

This results in improved imaging and coherence

CDM 2SE

Stand - mount/Bookshelf loudspeaker system


The CDM 2SE is ideal for the smaller room, as it offers superb sound from a compact

enclosure.

An integral part of the CDM 2SE is the use of rounded baffle edges, which reduce the

effect known as diffraction. In normal cabinet construction, sound waves from the drive units

radiate toward both the listener and the cabinet edges. If the sound waves meet sharp

edges, they re-radiate towards the listener and, due to time delay, interfere with and blur

the sound coming directly from the drive unit. Rounding the edges reduces this time

smearing, giving you the listener a clearer sound and better defined stereo image.

Audio Analogue Crescendo Tuner/USBDAC

The Crescendo Tuner/USBDAC is an extremely interesting and innovative product. It is not just a Tuner but also includes an entire high performance USBDAC section. The Crescendo Tuner/USBDAC can be seen as two different audio sources combined in a single piece of equipment, each source corresponding to a different working mode: Tuner Mode and USBDAC Mode.

The specific circuits for each mode are completely separated physically and just one section at a time is supplied, according to the selected mode (This avoids any kind of interference between the two signal paths). Instead, the analogue output stage is the same for both of the modes. Everything has been realized according to the well known Audio Analogue experience. The power supply is based on a toroidal transformer and each section has its own voltage regulator stage.

The tuner is based on a high performance circuit already used by Audio Analogue on its tuner products. The whole tuner section has been realized in a metallic separated box to shield the RF interference and a special buffer stage has been put between the tuner section and the output stage to further decrease the RF noise.

The USBDAC section is composed by a dedicated section which, working on the USB data, supplies a SPDIF digital audio signal. The digital audio signal is then converted into an analogue one by a high performance DA section composed by: a 96 KHz/24Bit, very low recovered system clock Burr Brown receiver (residual jitter less than 50ps!) and a 24 Bit/192KHz Enhanced Multilevel Delta Sigma architecture DAC (The conversion circuit is placed on a separated board to avoid any high frequency disturbance on the audio signal).

The Crescendo Tuner/USBDAC is controlled by a microcontroller and both the switches on the front board and the remote switches have different functions depending on the mode the unit is working on. The Crescendo Tuner/USBDAC has a very reliable low emission display to not interfere with the audio signals.

All the components, passive and active have been chosen considering their electrical characteristics and sound performance too.

The USBDAC permits you to connect the Hi-Fi system to the PC or MAC via a USB connection. In this way the PC/MAC sees the Hi-Fi system as its audio board and everything which is played on the PC/MAC is reproduced by the Hi-Fi System. This opens up a wide spread of possibilities which we think will be soon appreciated by every, also “old style”, audiophile:

• Listening to tracks in any format (MP3, WMA, FLAC, APE and so on…..) which you have in your PC via a software player. In such cases, according to the player, you can also control the PC (Next track, Previous track, Play, Stop, Pause) by the Crescendo Tuner/USBDAC front switches or remote.

• Listening to an on-streaming tuner. On the web there are a lot of tuner stations which transmit on-streaming, so a lot of stations from everywhere in the word can be listened to.

• Listening to audio movie tracks which are playing on the PC.

The Crescendo Tuner/USBDAC has also a SPDIF Out which can be sent to an external DA converter.

The Crescendo Tuner/USBDAC has both the Trigger In and Trigger Out connections so it can be switched on/off by another unit of the chain and also can switch on/off another unit of the audio chain.

SME 3009 & 3012

SME precision pick-up arms offer a standard of design and engineering which has earned them many distinctions. Throughout the world thousands are in daily use by enthusiasts, profesionals, broadcasting and recording companies, who appreciate a specification that is eminently suited to the needs of modern high quality sound reproduction.

The realism and clarity of a stereo record reflect the skill and technical perfection underlying its manufacture. Only when this is maintained in the reproducing equipment can justice be done to the art of the recording engineers. In playing a gramophone record the stylus must follow a path of extraordinary complexity and be highly compliant if the minute detail of the groove is to be traced without damage. Even the best cartridge cannot achieve this unless it is poised free from extraneous influences. The design of a carrying arm capable of realizing the full potential of pick-up and record is highly specialized involving many problems. These have been successfully resolved in the SME, an instrument of unrivalled quality presented with confidence that the user will endorse the claim "The best pick-up arm in the world"

Two models are made, 3009 and 3012, pivot to stylus distance 9 and 12 inches respectively. The most popular is the 3009 because it can be accommodated in a smaller space. It is also lighter and for this reason sometimes preferred for a very high compliance cartridge. However, the 3012 is also suitable in this respect as the effective mass is not greatly different and is further reduced by an improved dynamic damping system now fitted. Tracking error is lower which is an advantege, especially when using an elliptical stylus.

Extremely low pivot friction is achieved by the use of high precision ball races protected against the entry of dust. The tonearm is carried on knifeedge bearings. Approximately ,020 gramme applied at the stylus will deflect the arm vertically or laterally. The bearings never require adjustment.

Low inertia. This is as important as low friction and must be considered with it. Careful design of the balance system and choice of material for tone arm and shell keep inertia suitably low in either model for high compliance cartridges.

Low distortion due to tracking error is provided by geometry which aims at lowest distortion rather than lowest tracking error. Intermodulation distortion due to the latter varies in inverse proportion to the radius. Thus an error of ½° at 2" radius would cause as much distortion as 1½° at 6" radius. Speedy and accurate adjustment for optimum tracking is made as shown opposite.

lever operated hydraulic raising and lowering control effective anywhere over the record giving automatic controlled descent-fascinating to use-safeguards valuable records.

Bias adjuster. The working of this important feature is explained opposite. The SME system is functional and adjustable for different tracking forces. Its simplicity ensures long term stability not otherwise obtained.

Cartridges weighing from 3 to 17 grammes can be balanced longitudinally and laterally. The arm is, itself, a precision balance and a predetermined tracking force of ¼ to 5 grammes can be applied exactly. No gauge is required and accuracy exceeds by far any but professional measuring devices.

The 4' miniature co-axial connecting lead has a capacity of only 27 pf. per foot ensuring that electrical resonance with cartridge inductance will be well outside the audio range. Terminated at one end to fit the shielded output socket under the arm and with SME Precision Phono Plugs at the other. Other lengths, 2' and 6' are available.

Shell accepts all cartridges with ½" fixing centres. Includes connecting tails with pin jacks, finger lift and light alloy mounting hardware. Weighs only 6 grammes and offers a valuable reduction in mass at the point of greatest effect.

Dynamic damping of the arm mass-stylus compliance resonance is obtained by dividing the arm mass into two portions joined by an elastic coupling of improved design. This system is also effective in rejecting rumble frequencies.

Camera finish in satin-chrome gun-black and anodised alloy. All parts precision machined, heat-treated and ground where necessary.

Rational development. Time to time improvements can by incorporated in earlier Series II arms.

Pioneer P-D1 (1983)

The P-D1 Compact Disc Player: Proof of Pioneer leadership in laser and audio technology.

The Compact Disc represents a radical departure from conventional analogue forms of music reproduction. The sound quality of a CD player relies on more than just the digital circuity. Analogue circuitry - a series of stages after the D/A converter - handles music in its original analogue audioform.

The very best analogue technology is needed to ensure that distortion does not creep in at this final stage. That's why for the P-D1, we,ve used our finest audio circuitry built around select parts such as our polypropylene capacitors. Pioneer's unmatched reputation for excellence in analogue audio technology is your guarantee of incomparable sound quality.

Yamaha PX-2 and PX-3


Yamaha PX-2
Natural Sound Linear Tracking Turntable
The PX-2 employs a highly sophisticated linear tracking mechanism which enablos it to actually achieve the linear tracking ideal: precisely recreating the movement of the head which originally cut the record. Truly accurate, faithful sound reproduction has finally become possible. This mechanism, combined with yamaha's symmetrically balanced, optimum mass, straight tonearm and quartz-lock PLL-servo direct drive system, provides unparalleled turntable performance. Operating convenience is also far above average, with two-speed tonearm positioning, one-touch disc size selection/play initiation, repet function, and IC logic controls.

Specifications:
S/N Ratio: 80 dB
Wow and Flutter: 0,01%
Dimensions: 493 x 156 x 428 mm (W x H x D )

Yamaha PX-3
Natural Sound Linear Tracking Turntable
Yamaha technology allows the PX-3 to take full advantage of the linear tracking design to deliver truly natural music reproduction. The Yamaha linear tracking system virtually eliminates tracking error and inside force for greatly reduced distortion, minimum crosstalk, and exceptional stereo imaging. Like the PX-2, the PX-3 also incorporates a straight perfectly symmetrical, optimum mass tonearm and quartz-lock PLL-servodirect drive system. This turntable is a pleasure to operate, as well, thanks to a specially developed Yamaha logic LSI which provides extensive control convenience and flexibility. Operation is fully automatic, with two-speed tonearm positioning and repead capabilities also included.

ADC - The Pritchard Pickup System

Your Pritchard Pickup System is a precision instrument built to the highest engineering standards. It should, therefore, be treated with every reasonable care.

Audio Dynamic's reserch in stereo sound made the five essentials of truc stereo reproduction possible with the amazing ADC cartridges. But these essentials are dependent upon the use of a dynamically balanced tone arm capable of tracking at less than 1 gram.

After intensive development, Audio Dynamics now presents an entirely new pickup system. It combines the highly compliant ADC-1 stereo cartridge and a remarkable tone arm that guarantees you all five essentials of true stereo reproduction.

The Pritchard Pickup System gives you a true, dynamically balanced tone arm. Unlike other systems, the heavy adjustable counterweight occupies a minimal amount of space behind the mounting. To adjust stylus tracking force, you simply move the counterweight until the arm is in perfect balance. A fine adjustment allows the system to track at the precise force required by the cartridge design. With the ADC-1, the Pritchard system tracks at ¾ gram.

Beacuse of its low inertia, the system tracks each side of the groove perfectly, ever if the record is warped. To stabilize the force created between the disc and the arm, a side thrust to maintain even pressure on both sides of the groove wall. A single ball bearing mount minimizes friction.

Additional features make the Pritchard system not only a masterful achievement in design but also a superb piece of equipment to handle. The visible stylus tip makes record cueing especially easy. A unique built-in arm rest unit eliminates the troublesome problem of locating the rest position. You simply clear the arm of the record and the arm positions itself. Furthermore, the system is so light and properly balanced, there is no tendency for the arm to "get away" when positioning it to play. Finally the Pritchard Pickup Sytem by Audio Dynamics is not a formidable looking piece of technical equipment. Its clean design and ease of operation make even the novice secure in handling it.

All these features give you a perfectly balanced tone arm combined with a cartridge which guarantees the five essentials of true stereo reproduction. If you are an owner of an ADC-1 cartridge, all you need is the Pritchard tone arm. If you do not posses the ADC-1 and are searching for a truly remarkable pickup system, hear the Pritchard by Audio Dynamics.
