Descriptions:

> Optimized T'ang-ku-la Amplifier Architecture
> The T'ang-ku-la architecture adopts a new three-stage feedback circuit (patented technology), effectively reducing circuit noise and high-frequency distortion, thus further enhancing the dynamic rane to a record-breaking 151dB and the full-band THD (90kBW) to 0.00003%. Additionally, this new technology effectively lowers circuit heat generation, improving reliability and extending service life while minimizing thermal noise. The three T'ang-ku-la modules form a 6-channel fully differential balanced architecture, maintaining full differential balance from source to output, achieving a true full-link differential balanced amplification. The headphone amplifier delives a driving power of up to 22,000mW (@16Ω).

> Focus On The Music
> A900 is TOPPING's brand new ultra-flagship HiFi headphone amplifier, born from our relentless pursuit of ultimate sound quality. Its refined industrial design perfectly reflects our music-focused philosophy.

> The clean, angular lines are not jsut structural - they reflect a deeper appreciation for aesthetic order. Bold yet restrained, like precisely arranged notes in a composition, the design strikes a balance between logic and emotion. Beneath its cool exterior lies a sound that is refined - the essence of the A900's dual nature.

> The rear panel features high-quality Neutrik connectors, offerign three sets of stereo combo balanced inputs. This design ensures broad compatibility with a wide range of professional audio equipment, catering to both audiophiles and studio users with diverse connectivity needs. 

> A900 is equipped with a full range of headphone outputs, providing up to six physical ports that fully support four mainstream headphone connection standards - including 6.35mm single-ended, 4.4mm balanced, 4-pin XLR balanced, and dual 3-pin balanced outputs. Utilizing premium-grade connectors from Neutrik and Japan's NDICS company Pentaconn, these outputs deliver stable, reliable performance. Users can configure the outputs as independent or simultaneous, allowing for personalized monitoring in various. 

> The A900 also includes preamp outputs and offers a dedicated pure preamp mode. As a preamplifier, it matches the headphone amp's flagship performance, with THD+N <0.000055%, making it an ideal companion for power amplifiers to reproduce music with stunning fidelity. 

> Responsive control
> A 2-inch full-color display provides clear real-time playback information. On the right, three touch-sensitive buttons work seamlessly with the volume knob to enable fast and intuitive adjusments. The knob not only offers precise  volume control, but also serves as a customizable function key - tailored to suit your personal preferences.

> With a simple operation, you can effortlessly switch between multiple display modes - such as playback information, FFT spectrum, or VU meter - providing real-time feedback on audio performance. The A900 also offers a choice of 9 background colors, allowing you to tailor the visual interface to your personal aesthetic preferences.

> Premium Remote control
> The main part of remote control is crafted from a single block of high-strength aluminum alloy using precision CNC machining, followed by fine sandblasting for a refined finish.

> Fully Balanced Relay Volume Control
> The A900 features a fully balanced relay-based volume control system, reducing channel crosstalk to -153dB. This ensures exceptional sonic purity and separation, bringing vocals to life with vivid presence and revealing the finest textures in instruments. With precise 0.5dB step volume adjustments, changes in volume are smooth and nuanced - delivering a refined and comfortable listening experience.

> Isolated Power Supply
> The power supply for the digital processing circuit is physically isolated from the two analog amplification circuits, delivering more stable, reference-grade voltage and effectively reducing interfernece.

> Flagship Pairing
> Pair with TOPPING's ultra-flagship DAC - the D900 - to form a high-performance DAC & amp combo. With a full range of input and output interfaces, this setup is not only fun to use but also lets you experience hi-end-level acoustics.
