T+A HA 200 Headphone Amplifier / DAC

The HA 200

Our first headphone amplifier is a new and ground-breaking development in which the analogue amplifier section, the converter section and also the case mechanics operate to perfection. The analogue section of the HA 200 is based on the unique T+A HV technology. Its high-performance output stages operate in Class-A mode with a high idle current, and are effortlessly capable of driving even the most difficult of headphones. The impedance of the three headphone outputs can even be matched to the headphones in use and the individual sound ideas. A crossfeed function for creating a sound stage image positioned in front of the head is available on request. The high-quality mains sections – one digital, one analogue with two separate torroidal transformers- provide very generous reserves of power.

The digital section is fitted with the proprietary T+A True 1-Bit digital / analogue converter, which provides an incredible DSD 1024 for Bitstream, and the T+A quadruple converter with 32 Bit / 768 kHz for PCM. Like all current T+A DACs the new HA 200 also features a sophisticated and completely separate decoder architecture for DSD and PCM, ensuring that all digital formats are decoded to the finest standards.
The design and materials of the case harmonise perfectly with the unique electronics. The HA 200 is significantly larger and heavier than other headphone amplifiers, but this is not surprising given the more than 2300 components and the sophisticated HV technology. All the case components are produced from non-magnetic aluminium, and the front panel is machined from solid plate material – just like the HV series. Accurate QPPM metering instruments and a large screen supply important system information, and provide an accurate indication of operating conditions. The FM8 IR remote control controls all functions of the HA 200.
We have designed the HA 200 in every respect with no hint of compromise and without regard to cost, for we had only one goal in mind: musical reproduction to the very highest standard of perfection.


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.
