What customers say
The Peachtree Audio GaN400 Power Amplifier earns high praise for its exceptional sound quality and advanced technology. Users consistently highlight the Gallium Nitride implementation, which delivers remarkable clarity, speed, and transient accuracy across all frequencies. This amplifier successfully merges the powerful grip of solid state with a natural fluidity often found in tube designs. Complex music is rendered effortlessly, supported by deep, controlled bass. A significant practical advantage is its high efficiency, allowing it to run cool despite substantial power output. While positioned in the high end, reviewers agree the performance justifies the investment, offering true fidelity that rivals much costlier components. It is highly recommended for audiophiles seeking dynamic realism.
Know before you buy
GaNFETs switch significantly faster and more accurately than traditional MOSFETs. This results in a more precise waveform reproduction, which gives the amplifier its signature blend of tube-like musicality and the tight, punchy dynamics typical of high-end solid-state designs.
Yes. The GaN400 is designed to handle speaker loads ranging from 2.5Ω to 16Ω. With its 850-watt regulated power supply, it maintains stability and control even with demanding, power-hungry speakers.
The GaN400 features a fully balanced topology, which provides a cleaner signal path and better noise rejection when paired with a balanced preamp. However, it also includes unbalanced inputs, so you can achieve excellent results using standard RCA connections if your source equipment is not balanced.
Because the GaN400 operates at approximately 96% efficiency, it converts the vast majority of its power into audio output rather than waste heat. This allows the unit to run much cooler than traditional Class A or AB amplifiers while consuming less power during operation.
Absolutely. With 400 watts per channel and a focus on low global negative feedback, the GaN400 is engineered for critical listening. It is designed to provide a natural, engaging soundstage that satisfies the requirements of discerning audiophiles.
