In designing the A 200 output stage it was T+As 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.
T+A believes in power when it can be used in practice with efficiency and precision. In the search to achieve the optimum blend of sound quality, power and efficiency, T+A has 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 T+A succeeded in converting raw power into unsurpassed audiophile performance. All circuits and circuit boards are designed and executed by the 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.
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.
Features:
- 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)
The T+A 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.
The T+A 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.
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.
