T+A A200 Power Amplifier – Silver

German Hi-Fi company T + A were founded in 1978 and have been following their own particular path ever since. They believe in the science of Audio and have built their reputation on building the “optimum” level of equipment “good enough” for them is not good enough! Here we have an example of one of their “High End” A 200 power amplifiers. It is in very good condition and is supplied in original factory packaging along with manual, mains cable, ethernet cable plus our standard three month warranty.
T + A Say….
Is High End compatible with the Midi format? Doesn’t a small system necessarily involve a loss of performance and functionality in favour of external appearance?
Our vision for the Series 200 is that it overcomes these contradictions. The DAC 200, HA 200, MP 200 and A 200 celebrate music, technology and the sheer pleasure of enjoying music.
Each unit of the Series 200 is instantly recognisable as a T+A device. The reason behind this is a design language that we have refined over more than forty years, whose progressive nature is based on the principle of reduction.
The double chamfer of the front panels softens the vertical format, and creates the illusion of a flowing transition between the front panel and the main body, without diminishing the devices’ crisp appearance.
The shoulder lines extend the Series 200 and give the units a compact silhouette which helps further to mask their actual dimensions in visual terms.
Design details such as VU meters and cooling fins underline the potential performance of the Series 200 even when at rest; once switched on, these features graphically celebrate every Watt of power in an impressive manner, as well as delivering additional information regarding the system’s status.
The Series 200 also represents a break with another paradigm: the devices have been developed with the aim of providing impressive performance both alone and as a system. Our in-house T+A SYS-Link system forms the basis for communication and data transfer within the series. Each individual device also gains in versatility as part of a network.
Every one of our thoughts and actions is aimed at reproducing sound to the highest possible standard. The SYS-Link prevents unwanted digital signals in the analogue signal path, allowing the music to sound out with the same authenticity, precise presence as the artists conceived and recorded it.
Ultra-high audiophile power – for many people a contradiction in terms, but we see it as a challenge. The A 200 offers a continuous output of 2 x 250 Watts at 4 Ohms, without compromising on finely drawn resolution and detail dynamics. Its heat-sinks provide an impressive indication of its potential power as well as ensuring efficient heat dissipation – even at full load.
The A 200 output stage operates as a high-performance complement to existing systems. In conjunction with the Series 200 it transforms the analogue signals from the DAC 200 into very high power for loudspeakers.
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. In the voltage amplifier stage our HV circuit technology, which is unique in the world, ensures outstandingly natural linearity, and at the same time eliminates harsh negative feedback.
The sine-wave mains power supply delivers huge quantities of current with no inertia, while the Class D PURIFI output stages effortlessly supply 2 x 250 Watts of continuous power to the loudspeaker terminals into 4 Ohms, without any trace of distortion or background noise. The frequency response is totally linear, and – in contrast to conventional Class D amplifiers – remains so entirely independent of load. Thanks to special input and output circuitry, bi-amping, whether horizontal or vertical, represents no obstacle.
The output stages are designed with a broad bandwidth and are capable of handling even the frequencies up to 60,000 Hertz. This design ensures that the output stage provides ample capacitance for the transmission of typical music signals without prematurely approaching its own limits.
The function of the mains section is similar to that of a sports car’s suspension: in itself it is almost invisible, but it is nonetheless crucial to overall performance. That is why our T+A high-frequency sine-wave mains sections operate at double the frequency of conventional mains sections, and in a pure sine cycle. Detrimental induced interference in the audible range, which is usually a problem, is effectively eliminated in this way. To remove the last trace of interference from the signal, T+A reservoir capacitors are recharged 100,000 times per second – 2,000 times faster than standard capacitors.
So much power in such a small space is monitored by the T+A Intelligent Safe Control circuit, which intelligently regulates the output as soon as there is a threat of excessive temperature, overload or clipping.
