I have a legendary Plinius Reference SA-250 MK III available.250W per channel or bridged mono provided 1000W.It has switchable class A/Class AB operation.See manufactures original sales brocher with all specifications below.The amplifier is incredibly well built at around 65kg and provides a rich...
Compared with a typical used integrated at this level, A$4,200 is a strong buy: it sits below the A$4,352 25th percentile and comfortably under the A$4,504 median, so this is priced on the buyer-friendly side of the market.
The SA-250 is well regarded for its authoritative grip, smooth yet punchy presentation, and real-world drive with difficult speakers, which is why it keeps a loyal following. In excellent condition, the appeal is even better: you’re buying a serious high-current amp at a sensible price, with the main upside being flagship-level sound without paying median-market money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Plinius Audio: New Zealand's Amplifier Specialist
Plinius Audio Systems was established in 1980 by Peter Thomson, a mechanical engineer based in New Zealand who developed a passion for high-fidelity amplifier design. The company gained rapid recognition within its home market and solidified its position through a 1987 merger with Craft Audio Limited, bringing designer Gary Morrison into the fold. This partnership proved pivotal, establishing Audible Technologies Limited as the production entity and introducing the asymmetrical circuit design philosophy that would define the brand's engineering approach. Today, Plinius remains headquartered in Christchurch, New Zealand, where all design, manufacturing, and marketing operations are conducted in-house.
Plinius has built its reputation almost exclusively around power amplifiers and preamplifiers, with particular acclaim for their Class A designs. The company's product lineage spans from early dual-mono configurations in the 1980s through sophisticated monoblock amplifiers and refined preamp stages. Their engineering ethos emphasizes meticulous hand-assembly and attention to sonic detail, with each unit individually built by dedicated craftspeople. This focused product strategy—rather than diversifying into speakers, digital sources, or accessories—reflects the brand's deep specialization in amplification.
Positioned as a high-end, boutique manufacturer, Plinius commands respect among serious audiophiles despite limited mainstream visibility outside New Zealand and select international markets. The brand is recognized for producing powerful, sophisticated amplifiers that prioritize sonic purity and engineering integrity over mass-market appeal. While once more prominent in enthusiast circles, Plinius maintains its standing as a niche, quality-focused producer valued by discerning listeners who prioritize amplifier excellence and New Zealand craftsmanship.
