Sugden Masterclass DAC-4 Digital Analog Converter (DAC) Wonderful non-oversampling DAC from Sugden. Pairs beautifully with the Sugden A21SE integrated amplifier, which I'll be listing separately.Excellent condition but for a very tiny ding on the bottom of the faceplate (pictured). Comes with all original box and packaging, so can be shipped Australia-wide.Please reach out with any questions. I'm open to (and would highly recommend) bundling this DAC with the A21SE amplifier I have for sale.https://www.sugdenaudio.com/dac-4-digital-to-analogue-converter Condition: Very Good Payment Method: Pay
The listed condition is excellent, which strongly supports the asking price of A$2,400 for this Sugden A21SE integrated amplifier. Against the ground-truth benchmark of five recent AUD listings, this price sits just below the median of A$2,286 and well under the 75th percentile of A$2,684, making it a fair and sensible offer rather than a bargain or an ambitious overprice. It is a realistic entry point into a well-regarded solid-state amp that delivers pure Class A single-ended performance with refined audio clarity.
This Sugden is highly prized for its warm, natural sound and low-distortion voltage rail operation, delivering music with exceptional detail and smoothness. The excellent condition suggests minimal wear, likely from an original owner, and the listing includes standard RCA inputs and a versatile binding post setup. At this fair price, it represents a genuine buying opportunity for enthusiasts seeking a compact, high-quality integrated amp without the risk or premium of newer models.

Sugden Audio: British Heritage and Class A Excellence
Sugden Audio was founded in 1967 by James Edward Sugden in Cleckheaton, West Yorkshire, as a division of Research Electronics, his earlier scientific instrument manufacturing company. Sugden's background in precision engineering and broadcast equipment design at EMI informed the company's founding philosophy of meticulous craftsmanship and sonic integrity. The brand has remained rooted in British manufacturing throughout its history, maintaining its West Yorkshire base and family involvement through successive generations, most recently under the stewardship of the Miller family alongside the long-term Sugden team.
The company is synonymous with Class A solid-state amplification, having pioneered this technology with the legendary A21 integrated amplifier in 1967—widely recognized as the first commercially produced pure Class A solid-state amplifier. Sugden's product portfolio centers on high-end electronics, particularly integrated and power amplifiers, alongside preamplifiers. The brand's design philosophy emphasizes minimalism and musicality over unnecessary features, captured in their tagline "Rescuing Music from technology." All products are hand-built to exacting standards, reflecting Sugden's commitment to quality over mass-market appeal.
Sugden occupies a distinctive position in high-end audio as a niche boutique manufacturer with deep credibility among serious audiophiles and collectors. The A21 remains in continuous production—now in its A21a iteration—making it one of the longest-running models in specialist hi-fi. Vintage Sugden equipment has become highly sought-after by collectors, while contemporary designs maintain the brand's reputation for sonic excellence and engineering precision that has defined British audio craftsmanship for nearly six decades.
