The Radia A25 is an integrated amplifier with built-in DAC and phono stage from Arcam, part of the current Radia series, sharing the A25+'s output power specifications closely. The Radia A25 brings Arcam's more accomplished current engineering to a complete, feature-rich integrated chassis.

Key specs that matter

Three single-ended inputs are provided. Output power is 2 x 100W into 8 ohms, rising to 2 x 165W into 4 ohms, matching the A25+. Signal-to-noise ratio is an exceptional 106dB, also matching, with total harmonic distortion plus noise at a near-immeasurable 0.002%. At 431 x 344 x 83mm and 9.18kg, the Radia A25 shares the A25+'s chassis dimensions closely within Arcam's current Radia-series naming.

Sound and use context

Expect a genuinely accomplished amplification character reflecting the exceptional 106dB signal-to-noise figure, with the built-in DAC and phono stage covering both digital and analogue vinyl sources directly.

Pairing

The built-in DAC and phono stage cover both digital and analogue vinyl sources directly without needing separate outboard devices.
