Perreaux SA3 and PMF 5150 B

Overview

This Perreaux set combines the slim SA3 stereo preamplifier with the enormous PMF 5150B MOSFET power amplifier. Both date from Perreaux’s ambitious 1980s period, when the New Zealand manufacturer became known internationally for unusually powerful solid-state amplification and clean, purposeful industrial design.

Why This Pair Matters

The PMF 5150B is the centerpiece. Introduced in 1983, it is rated at 500 watts per channel into 8 ohms from 20 Hz to 20 kHz with no more than 0.03% total harmonic distortion. Period specifications also describe very high continuous and dynamic output capability, making it one of the most formidable stereo amplifiers of its era. This is not marketing-driven “big power”; the amplifier was engineered for demanding loudspeakers, substantial current delivery, and large dynamic swings.

The SA3 provides a suitably versatile front end. Perreaux documentation dates it to 1985 and specifies both moving-coil and moving-magnet phono inputs, dedicated compact-disc and line-level inputs, multiple tape connections, and a wide 20 Hz to 50 kHz frequency response. Despite its low-profile chassis, it is a full-featured analog preamplifier rather than a stripped-down passive controller.

Highlights

• New Zealand-designed 1980s preamp and power-amplifier pairing
• PMF 5150B rated at 500 watts per channel into 8 ohms
• High-current MOSFET power-amplifier design
• SA3 with moving-coil and moving-magnet phono stages
• Dedicated CD and multiple line-level inputs
• Wide-band preamplifier response
• Built for systems requiring exceptional power reserves

Who It’s For

This combination is for the enthusiast who needs genuinely massive amplifier capability without giving up analog source flexibility. It is particularly compelling for large rooms, inefficient loudspeakers, or collectors interested in Perreaux’s most imposing classic-era electronics.
