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.

Nous ne croyons en la puissance que lorsque nous pouvons l'utiliser dans la pratique avec efficacité et précision. Dans notre recherche d'un mélange optimal de qualité sonore, de puissance et d'efficacité, nous avons développé une topologie de circuit entièrement nouvelle qui combine la technologie unique d'alimentation secteur sinusoïdale HV et haute fréquence de T+A avec celle des étages de sortie PURIFI Eigentakt™. Par ce biais, nous avons réussi à convertir la puissance brute en performances audiophiles inégalées. Tous les circuits et cartes de circuits imprimés sont conçus et réalisés par notre propre équipe de développement, et les modules PURIFI y sont implémentés. Le facteur d'amortissement de l'A 200 peut être réduit si l'on souhaite obtenir une image sonore plus chaude ou plus douce en combinaison avec des haut-parleurs particuliers.

Les étages de sortie de classe D de l'A 200 intègrent la technologie PURIFI Eigentakt™. Cette plateforme, développée par la société technologique danoise, est actuellement la première conception fondamentale au monde pour les étages de sortie de classe D, car elle éradique les inconvénients de la génération précédente d'amplificateurs numériques. Jusqu'à présent, les conceptions d'amplificateurs numériques étaient limitées par leur forte dépendance à l'égard de l'impédance des haut-parleurs connectés au système, par la distorsion du signal de sortie, par le bruit de phase et par une distorsion accrue à des niveaux de puissance élevés. En revanche, la particularité de cette nouvelle conception de circuit réside dans ses remarquables données mesurées, qui en font le choix évident pour les applications audiophiles

Strengths :

  • 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)

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.

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.

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.

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.
