Burson Audio HA-160 fully discrete Class A headphone amplifier in very good condition. Light surface markings on the top panel from careful use, otherwise excellent condition. Fully functional, no issues. Made in Melbourne, Australia.The HA-160 was one of Burson Audio’s earlier reference headphone amplifiers and helped establish the company’s reputation for discrete audio design. It avoids standard IC op-amps in the audio circuit, instead using Burson’s own discrete HD op-amp modules built from individual components. The circuit also uses a short signal path and no coupling capacitors in the signal path.Discontinued and increasingly hard to find in complete, working condition.

Burson Audio emerged in 1996 in Melbourne, Australia, from a collective of passionate audiophiles united by a pursuit of audio perfection. What began as a labor of love—pooling expertise in engineering, technology, and music for personal enjoyment—evolved into a commercial venture by 2005 with the release of their debut products. This grassroots origin underscores their unwavering commitment to innovative, no-compromise designs unbound by mass-market constraints.
The brand specializes in high-performance categories like Class-A headphone amplifiers, DACs, pre- and power amplifiers, and discrete op-amps, alongside integrated solutions such as the Conductor and Soloist series. Signature innovations include custom-designed op-amps, fully IC-free Class-AB amplifiers like the Timekeeper with its linear power supply, and the proprietary Max Current Power Supply (MCPS) technology. Their minimalist circuits prioritize transparency and power, often featuring high-current mono blocks and discrete components for audiophile-grade reproduction.
Burson occupies a niche boutique position in the high-end hi-fi market, revered by head-fi enthusiasts and discerning listeners for meticulous craftsmanship and exceptional sound quality. Independent and innovative, they stand apart through engineering excellence that challenges conventions, earning a global reputation among those seeking authentic, boundary-pushing audio without corporate dilution.
