T'ANG-KU-LA ARCHITECTURE:
\nAt the heart of the A900 is the patented three-stage T'ang-ku-la feedback circuit. It uses six channels of fully differential amplification to maintain balance from source to output. This design reduces circuit noise and high-frequency distortion, while increasing reliability and reducing thermal noise. The result is a wider dynamic range, cooler operation, and a sound that remains clean and controlled. With nearly 22,000 mW per channel at 16 \u03a9, the Topping A900 has room for even the most demanding headphones.<\/p>\n
The Topping A900 features a 2-inch color display that provides useful information and real-time playback details, an FFT spectrum or a VU meter. You can choose from nine background colors and easily switch between display modes. On the right side, three touch buttons and a responsive knob allow you to quickly and easily navigate and manage settings.<\/p>\n
Features of Topping A900:<\/strong><\/p>\n Six-channel T'ang-ku-la circuit with patented three-stage feedback <\/p>","protected":false},"excerpt":{"rendered":" The Topping A900 is a premium headphone amplifier designed for listeners who want massive power, sonic precision and the satisfaction of fully balanced reference-level sound. With a six-channel T'ang-ku-la circuit, true differential architecture, a signal-to-noise ratio of 151 dB and a peak output power of 22,000 mW x2 at 16\u03a9, the A900 delivers clean, powerful sound and outstanding control over any pair of headphones or monitors.<\/p>\n The Topping A900 offers six physical headphone outputs, including 6.35mm single-ended, 4.4mm balanced, 4-pin XLR balanced, and dual 3-pin balanced. Premium connectors from Neutrik and Pentaconn ensure a solid and reliable connection. The outputs can be configured as independent or simultaneous, so you can test or monitor multiple headphones without having to swap cables.<\/p>\n
