Perreaux was formed in 1974. The first product produced was the “GS 2002”, an integrated transistor amplifier capable of a whopping 22Wrms per channel. Over the next two years the company continued developing its products and was then producing preamplifiers, power amplifiers and loudspeakers for both the domestic and professional local markets.
The Audiant 80i is a stereo integrated amplifier equipped with an asynchronous USB DAC and is capable of delivering 80W of pure, distortion free power per channel.
Incorporating an upsampling 24-bit/96kHz digital to analogue converter (DAC), Audiant 80i uses ESS Technology’s Reference Sabre ES9006 DAC for accurate sound reproduction of all your digital sources.

BENCH TEST HiFi News:
Those manufacturers who insist on specifying their amplifiers
rather too closely to the wind could learn a thing or two from
Perreaux. This ‘250W’ Eloquence 250i integrated will, in fact,
deliver far closer to 2x420W/8ohm
2x670W/4ohm
with a thundering 545W and 1kW, respectively, under dynamic
conditions.
Protection circuitry limits its maximum current
delivery to 28.5A at 1% THD (Perreaux suggests a 45A ‘short
duration’ capability) which is sufficient to maintain 1.2kW/2ohm
and 810W/1ohm - Prisma 350
The Prisma 350 is a 350W per-channel stereo power amplifier. The high power output allows the 350 to effortlessly drive any loudspeakers with the precision, detail and authority that Perreaux products are renowned for.
The ability to extend deep into the lower octaves with control and finesse delivers instruments and voices with lifelike heft, body and scale. Sonic transparency is deep at the heart of the 350, allowing the musicians artistic prowess to be realised in its entirety and as intended by the mastering engineer.

Ultra Stiff Power Supply
The 750 incorporates a massive custom designed, toroidal power transformer, employing unusually heavy gauge wire that reduces copper losses to a minimum. An electrostatic shield prevents AC line borne interference from entering the signal path. The power supply filter capacitors, totaling 60,000uF, have exceptionally low inductance and internal resistance. They charge and discharge in response to load demand far more rapidly than conventional storage capacitors and are capable of delivering the instantaneous current required by the output stages, providing optimum dynamic range and transient response. The wiring from the power supplies to the output boards is designed for unimpeded transmission of the required current and voltage and utilizes heavy gauge, tinned copper wire cables. Since power supply leads radiate at signal frequencies, all wiring is carefully loomed to minimise this effect.
Hybrid Class-A/AB
The bi-polar transistors used in the 750 are operatin in Class-A. This avoids the crossover notch distortion and the resulting odd-order harmonics present, to some degree, in all other classes of operation. The devices used in the 750 output stage are MOSFETs, which with high quiescent current circuitry, are run in the equivalent of Class-A to 10 watts. Beyond this point the output class is technically Class-AB (hence the hybrid nomenclature), but with a major difference. The combination of MOSFET characteristics and their application in this circuitry, result in crossover distortion so minimal that it is virtually non-existent.
