Audio-gd, a high-end Chinese audio brand, traces its origins to over two decades of operation, with products like the DAC-19 now marking a tenth anniversary. Founded and led by Mr. He Qinghua, a First Prize winner in the National Semiconductor (USA) Audio competition, the company has built its heritage on innovative engineering from China, emphasizing proprietary technologies such as the ACSS (Audio-gd Current Signal System) for current-domain signal transmission.
The brand specializes in two-channel hi-fi components, including DACs renowned for R2R ladder converters, preamplifiers, headphone amplifiers, and balanced designs in its flagship Master and HE series. These products incorporate advanced features like regenerative power supplies, positioning Audio-gd as a purveyor of digital-to-analog converters and amplification solutions rather than speakers, turntables, or headphones.
Audio-gd holds a strong niche in the high-end market, celebrated for exceptional price-to-performance ratios that deliver refined, silent soundscapes—earning multiple Qobuzism awards for standout models. Boutique appeal draws discerning buyers seeking value-driven excellence over mainstream luxury pricing, with a reputation for technical prowess that shocks even seasoned audiophiles.
