Tonewinner AT300 AV Processor

Tonewinner traces its roots to China, where a precursor company emerged in 1992 under founder Li Zhi, who pioneered audio circuit board innovations. Guangzhou Tonewinner Electronics Co., Ltd. was formally established in 1999 in the Pearl River Delta, leveraging a vast 10,000-square-meter facility and advanced production lines. For over three decades, it has honed expertise as a leading OEM manufacturer, quietly powering high-end components for global brands like Advance Paris, Nuforce, and Emotiva.

The brand excels in amplifiers, including multi-channel power amps and AV preamplifiers, alongside home theater systems, karaoke integrated audio, speakers, and Dolby Atmos-enabled AVRs and soundbars. Its portfolio emphasizes hi-fi power amplifiers—such as Class A two-channel models—and Bluetooth speakers, all produced with robotic precision, components from China, Taiwan, Japan, and the US, under ISO 9001 standards.

Positioned as a mid-tier powerhouse, Tonewinner delivers high-end performance at competitive prices, earning accolades like nine consecutive "most acclaimed product" wins at domestic exhibitions and early certifications for Dolby Atmos and HDMI. Exported to dozens of countries, it commands respect among savvy buyers seeking value-driven home cinema and hi-fi excellence from China's premier audio factory.
