About Plinius

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.
