Audio-GD Master9 Headphone Amplifier I’m a senior (90 next year) audiophile with too many toys and no descendants who appreciate hi-end electronics. I do not need 4 headphone listening stations so am offering this item to someone who appreciates both electronic craftsmanship and of course meticulously reproduced music! Note than for some time I spurned digital and stuck with vinyl but was eventually persuaded it could sound nice if better gear was used in the process. What I’m selling here is the result of many decades chasing audio moonbeams, and this item is capable of catching them! I
The asking price of A$1,650 sits comfortably between the median of A$1,154 and the 75th percentile of A$2,283 for used Audio-gd units, making it a fair market value rather than a bargain or an overpriced gamble. It reflects the typical cost for a well-maintained Master 9 in the current Australian market, aligning with the product’s reputation as a high-end, end-game amplifier.
This is a worthwhile buy because the Master 9 delivers pure Class A performance with ultra-low distortion and a neutral, uncoloured sound that excels across everything from IEMs to demanding full-sized headphones like the HE-6. Its clean listing, “As New” condition, and inclusion of both RCA and XLR outputs add significant value, offering timing upside as a rare, original-owner find at a solid price point.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
