The HA 200 headphone amplifier marks a significant achievement as it represents the first foray into headphone amplifiers by its creators. It brings together a synergy of analogue and digital technologies encased in meticulously designed mechanics. The analogue section leverages the distinctive T+A HV technology known for its robust output stages that operate in Class-A mode. This design choice ensures that it can efficiently drive the most demanding headphones with its ample idle current.

The versatility of the HA 200 is further enhanced by its ability to adapt to various headphones through selectable impedance on its three outputs, catering to the specific requirements and preferences of the user. An optional crossfeed function enhances the auditory experience by simulating a more natural soundstage directly in front of the listener.

Power supply robustness is a critical feature, with separate toroidal transformers for its analogue and digital sections that ensure ample and clean power delivery. The digital prowess of the HA 200 is highlighted by its proprietary T+A True 1-Bit D/A converter that supports up to DSD 1024 and a quadruple converter that handles PCM files up to 32 Bit/768 kHz. This dual-decoder architecture ensures that each audio format is processed with uncompromised fidelity.

Aesthetically, the HA 200 boasts a design that is both substantial in size and build, reflecting the complexity and high component count of more than 2300 individual parts. Constructed from non-magnetic aluminium, and featuring a front panel crafted from solid plate material akin to the HV series, it epitomizes durability and stylish design. Its operational status and system metrics are accurately relayed through precise QPPM metering and a large display screen. The inclusion of the FM8 IR remote control allows for comprehensive control over the amplifier's functions.

Overall, the HA 200 has been crafted without compromises, with a clear focus on delivering the highest possible quality in musical reproduction. This commitment to excellence makes it a pinnacle offering in the realm of headphone amplifiers.
