This US$9,995 asking price is ambitious, sitting well above the 75th percentile of US$4,591 and nearly double the median of US$3,106 for recent comparable listings. While the Plinius Reference A-150 was a flagship new-production model priced at US$13,000, the current used market for this specific unit reflects a significant gap between this listing and typical transaction values.
The A-150 remains a revered high-current amplifier, delivering 150W per channel in stereo and doubling to 450W in mono mode, with a reputation for matching Krell and Classé performance. Its dual-stereo/mono flexibility and robust New Zealand engineering make it a worthwhile long-term hold, but at this price, the buyer should verify the condition is truly excellent and confirm all original accessories are included to justify the premium over the established market range.
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.
