The T+A Solitaire® HA 200 Headphones Amplifier / DAC has arrived!
2020 will be remembered as the year in which T+A introduced a whole new family of products: headphones and headphones amplifiers. T+A develop a range of extremely innovative headphones and headphone amplifiers, evincing the same consistently systematic approach and commitment which T+A have always adopted in the development of its audio systems and loudspeakers.

The first model of headphone amplifier is the HA 200, and it benefits from our extensive expertise and several decades of experience in the development and manufacture of amplifiers and transducers. T+A of course have not been content simply to adopt existing technologies, preferring instead to develop and optimise them for the particular requirements of headphones.

The HA 200 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.

T+A 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.

T+A's intention in developing the HA 200 was to build a headphone amplifier with the finest sound quality available anywhere in the world, and suitable for all kinds of dynamic and magnetostatic headphones. This means that the amplifier section would have an absolutely crucial part to play in the overall design. And that’s why T+A decided to adopt the principles of our HV series: pure analogue Class-A design with special MOS-FET transistors, no op-amps, no chips and a separate 100-Watt analogue mains section. Even the crossfeed function is generated by an analog filter circuit.
The XLR and Cinch inputs take the same form as in the HV series, and the pre-amplifier is designed in such a way that it feeds the output stage in the optimum manner. Gas-tight encapsulated gold contact relays take over the volume control and adjustable loudness function and bridge the tone control completely (flat) on request, they are absolutely free of distortion and noise. Even after many years of operation these components are not subject to contact problems due to corrosion, dust or ageing effects. The relays are integrated directly into the circuit design, keeping the signal paths as short as possible.

Since T+A 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.
T+A 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.

Sound quality can be fine-tuned by selecting different output impedances for each output (6.3 mm, 4.4 mm Pentaconn, XLR 4-pin), and Crossfeed-mode can also be switched in.

The XLR 4-pin output can be used to drive loudspeakers if the user wishes to connect a stereo power amplifier (such as the AMP 8); in this case we can supply an XLR-4 to 2xRCA adaptor.

In addition to the conventional high-quality analogue inputs T+A 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-C 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 incorporated 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.

The 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.

Since T+A 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.
