About the a200 power amplifier

Series 200
The Series 200 represents a modern interpretation of our legendary MiDi systems. Starting with the iconic M-system in the 1990’s, and most recently continued by the Series 8, all of these systems have combined and continue to combine superb audiophile performance with an ultra-compact design of timeless elegance. The MP 200, A 200, DAC 200 and HA 200 embody our experience in each individual area, and make it accessible to compact systems in particular.

Design Principles
The Series 200 was developed with the goal of closing the supposed gulf between high-grade specialised individual devices – ‘separates’ – and a combined system for relaxed listening. And that’s why the Series 200 consists of four units. The DAC 200 and HA 200 reference converter and pre-amplifier convert digital data into analogue signals, and constitute the heart of their system configurations: the DAC 200’s outstanding pre-amplifier and output stages make it the ideal core of a classic HiFi system with loudspeakers, whereas the HA 200 takes on a similar role in an audiophile headphone system. Thanks to its Modular High-End Architecture (MHA) the MP 200 operates as a universal unit capable of delivering all modern music sources, from DAB radio to streaming. The A 200 output stage, generating 250 Watts power per channel into 4 Ohms, provides incredible performance with superb linearity and outstanding measured values. Thanks to the advanced technologies employed, the A 200 is able to exploit its full performance regardless of load, i.e. independently of the loudspeakers to which it is connected.
Although all the Series 200 devices offer outstanding levels of performance individually, the aim of their development was to make them even better when used together in a system. The integral T+A Link System has been fine-tuned to meet the specific requirements of the Series 200, with the result that every device is as universal as possible, as well as keeping interference signals completely separate from the analogue signal path: this ensures that the music remains just as clear and precise as it was when the artiste performed it.

External Design
Like every T+A device, the Series 200 units were designed on the basis of our unified philosophy of “timeless reduction”. This principle endows all the equipment we produce with a shared visual DNA, without obscuring their individual qualities. For more than twenty years now this philosophy – with a few exceptions – has been the beginning and end of each design process: a clearly delineated double chamfer on the front panel, reminiscent of the iconic M-systems of the 1990’s, giving the devices a unique charisma. Precisely positioned lines and style accents give the illusion that the Series 200 devices are smaller than they actually are. Cooling fins and VU meters are an unmistakable indication of the units’ potential performance – even when the equipment is switched off.

The A 200
In designing the A 200 output stage it was our goal to combine maximum amplifier power with audiophile sound characteristics. On the one hand this means 250 Watts of continuous power per channel, and on the other hand this substantial power does not result in a reduction in terms of subtle detail, resolution and fine dynamics. Its heatsinks are both a technical necessity and a design statement: they show off every Watt of power in impressive style as well as ensuring efficient heat dispersion – even under maximum load. The A 200 output stage was developed with the aim of functioning either as a potent complement to an existing system, or as the high-performance end of a perfectly matched chain of specialised audiophile devices in combination with the Series 200.

We only believe in power when we can use it in practice with efficiency and precision. In our search to achieve the optimum blend of sound quality, power and efficiency, we have developed a completely new circuit topology which combines T+A’s unique HV and High-Frequency sine-wave mains power supply technology with that of the PURIFI Eigentakt™ output stages. By this means we have succeeded in converting raw power into unsurpassed audiophile performance. All circuits and circuit boards are designed and executed by our own development team, and the PURIFI modules implemented within them. The damping factor of the A 200 can be reduced if a warmer or softer sound image is desired in combination with particular loudspeakers.

Output Stage

The A 200 Class D output stages incorporate PURIFI Eigentakt™ technology. This platform, developed by the Danish technology company, is currently the world’s leading fundamental design for Class D output stages, as it eradicates the disadvantages of the previous generation of digital amplifiers. Until now digital amplifier designs were limited by their high dependence on the impedance of the loudspeakers connected to the system, by distortion in the output signal, by phase noise and increased distortion at high power levels. In contrast, the outstanding feature of this new circuit design is its outstanding measured data, making it the obvious choice for audiophile applications

• Extremely low distortion factor and intermodulation distortion at all power levels
• Extraordinarily low noise
• High damping factor
• Clean clipping
• Low losses, high efficiency
• Totally linear frequency response up to 60 kHz
• Completely loudspeaker-load independent characteristics (see measured curves into 4 Ohms and without loudspeaker-load)

Mains Section
In spite of their advantage in terms of efficiency, conventional switching mains sections have an inherent drawback: they generate interference in the form of induced interference, which has a consistently adverse effect on sound quality. Our response to this is to employ our T+A High-Frequency sine-wave mains sections: their pure sine-wave output and higher frequency – more than twice as high as conventional mains sections – effectively eradicate this interference. The final trace of induced interference is eliminated by the intelligent recharging of the T+A reservoir capacitors fitted to the units. Over many years of development T+A engineers succeeded in developing capacitors which recharge 100,000 times per second – 2,000 times faster than conventional capacitors. This is necessary in order to ensure that they respond to extremely brief signal spikes, and are always able to deliver the correct quantity of electrical energy. Our sine-wave mains sections are “hard” units, i.e. they do not collapse even under the most severe load; they provide the output stages with absolutely constant voltage.

Intelligent Safe Control
Our Intelligent Safe Control (ISC) is comparable with the ABS of a sports car: the micro-controller uses numerous sensors to provide constant monitoring of the temperature, load or clipping states, and intervenes in an intelligent manner in order to return the parameters to their permissible range.

HV Circuit Topology
Our HV circuit technology is unique in the world, and is employed in the voltage amplifier stage. The high operating voltage resulting from the overall circuit design ensures extremely linear reproduction of the audio signals, and provides totally natural imaging and dynamics from every recording – without compromise, and without limitation. The technology also eliminates harsh feedback, to which audio sound is very sensitive.

Frequency Response
The frequency response is totally linear up to 60 kHz and completely independent of the connected loudspeaker. The measured curves show that there is no difference in frequency response between a 4 Ohms loudspeaker load and no loudspeaker load.
