Our Thoughts RADAR AI

The PMF 1150B has a strong reputation as a muscular, well-built vintage MOSFET amp, and US$575 is fair to slightly good for one in unknown condition. Comparable sold/asking examples I found land around US$350 for a ended listing and US$750 for an excellent-shape sale, so this listing sits in the middle of the usual used range rather than looking cheap or inflated.

What makes it worth a look is the combination of 100 watts per channel, dual-mono-style construction, and the kind of smooth, authoritative drive these Perreaux amps are known for. If it powers up cleanly, runs cool, and the seller can confirm all channels are healthy with no hum, scratchy controls, or protection issues, it’s a solid buy; with unknown condition, I’d want proof of recent service or at least a good demo before paying top of range.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Perreaux

Perreaux traces its roots to 1974, when Peter Perreaux founded the company in the small New Zealand town of Napier. From humble beginnings with the legendary GS 2002 Class A integrated amplifier, it quickly gained traction through meticulous design and handcrafted quality, expanding exports to Australia and the Americas by the late 1970s. Relocating to Dunedin in 2005, Perreaux has upheld its Kiwi heritage, blending innovation—like early MOSFET adoption in the SA80B power amp—with a commitment to superior sound reproduction.

The brand specializes in high-end hi-fi components, renowned for amplifiers, preamplifiers, and integrated systems that prioritize refined circuitry and rock-solid build quality. Its lineup also encompasses loudspeakers and select audio electronics, all hand-assembled with custom-selected parts, including bespoke transistors. Perreaux avoids mass-market diversification into turntables, DACs, headphones, or cables, focusing instead on core amplification and playback excellence.

Positioned firmly in the audiophile high-end market, Perreaux commands respect for its reliability, longevity, and uncompromised performance, distributed in over 30 countries. Collectors and discerning buyers value its vintage appeal alongside modern, future-proof designs, distinguishing it as a boutique powerhouse that outpaces competitors through precision engineering and timeless craftsmanship.
