The HA 200 headphone amplifier
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 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.
Technology
Our 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 we 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.
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-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 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 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.

Ohrenschmaus
Das nenne ich mit Fug und Recht einen Einstieg nach Maß. Mit dem Duo Solitaire P und HA 200 will T+A nirgendwo anders hin als an die Spitze. Dafür war kein Aufwand zu groß, keine technische und konstruktive Herausforderung unüberwindlich. Das Set kostet eine Stange Geld, aber klanglich müssen sich Mitbewerber in Zukunft an Solitaire P und HA 200 messen lassen, denn dieser Ohrenschmaus setzt Maßstäbe.

Theorie und begeisternde Anwendung
Billig sind die beiden High End Geräte Solitaire P und HA 200 von T+A nicht. Angesichts der gebotenen Qualität und der hervorragenden Umsetzung auch zukunftsweisender Konzepte erscheint ihr Preis aber angemessen, zumal dann, wenn der stolze Besitzer alle Möglichkeiten des HA 200 ausschöpfen kann. Die Kombination aus Solitaire P und HA 200 wird ihm, da bin ich mir sicher, neue Einsichten in musikalische Zusammenhänge und auch eine weitere Entwicklung der eigenen klanglichen Wahrnehmung ermöglichen.

Fazit T+A Solitaire P und HA 200
Viel Geld. Ein gläubiger Anhänger der Lautsprecher-Wiedergabe wird noch nicht einmal interessiert zucken. Was bedeutet: Die Zielgruppe für diesen Amp und seinen Kopfhörer ist fein geschnitten. Wer die beiden jedoch erleben durfte, wird vom Glauben abfallen und mit fliegenden Fahnen die Seiten wechseln. Ich traue mir den Superlativ zu: Das ist die beste Amp/Hörer-Kombi, die ich kenne. Der Preis tut weh. Aber so etwas kauft man sich auf Jahrzehnte. 11.400 Euro durch 365 Tage mal zehn Jahre – macht drei Euro zwölf Cent pro Tag. So gerechnet, kann man schon wieder drüber nachdenken.

Breaking new ground
Very few headphone amplifiers are able to take you on such an epic sonic journey when you slip on your cans, and combined with a seemingly endless array of tweaking options and flexibility, it´s very difficult to see this as anything other than the perfect option for those that take their headphone listening seriously. Just because it´s high-end doesn´t mean it doesn´t know how to have fun.

HA 200 headphone amplifier – HiFi Review
It is hard to fault such a fine piece of equipment, so I won’t. It is, simply a masterpiece of headphone amplifier loveliness. With such a high degree of flexibility, it will be difficult to find a pair of headphones that wouldn’t benefit from the dynamic control from this Class A product. It is the easiest 5 star of the year, what an outstanding headphone amplifier.

Technologie & Topologie
Auch messtechnisch unangreifbar perfekter Kopfhörerverstärker, der sowohl mit nieder- als auch mit hochohmigen Kopfhörern völlig problemlos harmoniert und dabei die Klangmesslatte ein gutes Stück nach oben verschiebt: T+A hat den wahrscheinlich besten Kopfhörer-Amp der Welt gebaut und kombiniert das Klangwunder mit den State-Of-The-Art-DACs des Hauses. Das Ergebnis hat seinen Preis, dürfte aber für lange Zeit kaum mehr zu toppen sein. Heißer Tipp: der HA 200 kann auch als Vorverstärker zum Einsatz kommen.
Musicalhead 5/2020
Dem deutschen High-End Hersteller T+A gelingt mit der überragenden Kombination aus SOLITAIRE P und HA200 somit ein veritabler Raketenstart in das internationale Kopfhörersegment, den man in diesem Maße so nicht erwarten konnte.
