With a six-channel T'ang-ku-la circuit, a true differential architecture, 151dB SNR, and a peak output of 22,000mW x2 @16Ω, the A900 delivers clean, powerful sound and remarkable control over any pair of headphones or monitors. \u003c\/p\u003e\n\u003ch3\u003eT'ang-Ku-La Circuit\u003c\/h3\u003e\n\u003cp\u003eAt the center of the A900 is the patented three-stage feedback T’ang-ku-la circuit. It uses six channels of fully differential amplification to maintain balance all the way from source to output. This design cuts circuit noise and high-frequency distortion while boosting reliability and lowering thermal noise. The result is greater dynamic range, cooler operation, and a sound that stays clean and controlled. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/topping-a900-circuit.webp?v=1758814745\" width=\"2048\" height=\"1200\" alt=\"Topping A900 headphone amplifier circuit graphic\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSix Headphone Outputs\u003c\/h3\u003e\n\u003cp\u003eThe A900 offers six physical headphone outputs, including 6.35mm single-ended, 4.4mm balanced, 4-pin XLR balanced, and dual 3-pin balanced.
