T+A | HA 200 - Headphone Amplifier
T+A's 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 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.
T+A have designed the HA 200 in every respect with no hint of compromise and without regard to cost, for they had only one goal in mind: musical reproduction to the very highest standard of perfection.
Amplifier Section
Since we had decided to cater for different headphone types, the output stage needed to be extremely sophisticated. Normal loudspeakers have impedances in the range 2 to 10 Ohm, which is not critical. However, headphones may have impedances in the range 10 to 1000 Ohm, and this certainly presents a challenge. Low-impedance types draw high currents, whereas the currents flowing in high-impedance types are relatively low; however, the voltage must be very stable. We overcame this problem by designing the output stage of the HA 200 to be capable of effortlessly delivering relatively high currents, while the mains section transformers (2 x 50-Watt) are extremely stable and constant.
ConnectionsThe wide range of connection facilities requires a very sophisticated control system and display for the amplifier as a whole. In fact, the HA 200 is intuitive and simple to operate, thanks to an ingenious combination of operating buttons and menu control system. The two VU meters (QPPM = Quasi Peak Programme Meter Type 1) are accurate indicators which display the variation in various parameters, as in studio applications and measurement engineering. The level at the D/A converter and the amplifier can both be displayed, as can input level and output level, temperature and stream quality (which can be used to check the frequency of the data stream and even the cable quality). The pin-sharp screen displays the user’s selected operating modes, such as output impedance, volume, data rate, oversampling filter type or crossfeed. The brightness of the display, the LEDs and the VU meter is adjustable. You can even adjust the colour of these.

Case DesignSince we have also designed the HA 200 for use in professional applications, the case is designed to be extremely solid and robust. The heatsinks are manufactured using an extrusion tool, the front panel is machined from solid metal, and the top, bottom and back panels are made from aluminium plates. Ultra-close tolerances and accurate fits are the hallmarks of this case, and at the same time the design provides for homogeneous heat distribution, leading to optimum operating conditions for the electronics as a whole.

iN & oUTPUTS
In addition to the conventional high-quality analogue inputs we have equipped the HA 200 with a large number of high quality digital inputs. This makes it possible to operate the unit as a stand-alone device, and connect it to various digital sources according to personal taste and requirements. There is no doubt that the HA 200’s digital input section is currently the world’s finest, since the USB-B inputs are based on the new high-resolution Thesycon chip, which can process up to DS 1025 and PCM 768. Professional AES/EBU and BNC sockets are also present, as are optical and co-axial SP/DIF. The Bluetooth input is fitted with AptX™ HD, two HDMI inputs (Stereo only) and one output ARC are available as options.
The extremely high quality of the inputs is maintained in the converter. 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, reflect the current State of the Art, and represent the limit of what is feasible today. The digital section features its own power supply, and is galvanically separated from the analogue section.
Although the primary purpose of the HA 200 is to be an amplifier with an extraordinarily high performance, this unusual flexibility on the input side is very helpful to various types of user. Since the amplifier employs our very finest DSD and PCM converters, the sound quality of the digital inputs is just as good as that of the analogue ones.
