1. Introduction to the Arcam A25 Flagship
The Arcam A25 represents the pinnacle of Arcam’s integrated amplifier engineering. As the flagship of the Radia Series, it is designed to drive the world’s most demanding high-end speakers with absolute authority. While its siblings offer incredible value, the A25 is built for the purist who seeks the highest possible fidelity without moving to separate pre-and-power components.
Wrapped in the sleek, minimalist Radia chassis with its signature yellow accents, the Arcam A25 is a statement piece. It manages to balance a massive power reserve with a delicate, nuanced soundstage, ensuring that whether you are listening to a solo cello or a full-scale orchestral climax, the reproduction is flawless.
2. Revolutionary Class G Amplification Explained
The defining feature of the Arcam A25 is its Class G amplification. Class G is a revolutionary technology that acts like a “turbocharger” for your audio. For most listening levels, the amplifier operates in pure Class A—offering zero crossover distortion and incredible sweetness.
When the music demands a sudden peak in volume or deep bass impact, the Arcam A25 instantly switches to a secondary power rail. This allows it to deliver a massive 100 Watts per channel without the heat and inefficiency of traditional Class A designs, maintaining a level of transparency that is usually reserved for amplifiers twice its price.

For those who enjoy private listening, the Arcam A25 includes a high-current headphone output and the ability to broadcast audio to wireless headphones. On the analog side, the built-in Moving Magnet (MM) phono stage is meticulously engineered to provide a low-noise, high-fidelity path for your vinyl collection.
