Against the obvious alternative of buying a standard new budget Class-D amp, £235 is a strong deal for this A20, especially with the Burson Vivid upgrade. It sits below the £248 25th-percentile point in 85 comparable listings, versus a £380 median and £713 upper quartile, so this is bargain territory rather than merely fair pricing.
The A20’s TPA3255 platform offers substantial clean power, balanced and RCA inputs, a useful subwoofer output, and plenty of headroom for demanding speakers. The Burson Vivid op-amp should add worthwhile refinement over the stock presentation, while the compact chassis makes it easy to build around. Check that the correct external power supply, remote or accessories—if applicable—are included, and ask for confirmation that both channels and the upgraded module work properly, but at this price the listing looks like a genuine buying opportunity.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
