Key specs that matter

Three single-ended inputs plus a dedicated phono input are provided. The phono stage uses the same genuinely sophisticated current-sensing design as the A15+ at 47,000 ohms. Output power is 100W into 8 ohms, rising to 165W into 4 ohms - considerably more than the A15+'s 80W/120W. Signal-to-noise ratio is an exceptional 106dB, matching the A15+, with total harmonic distortion plus noise at a near-immeasurable 0.002%. At 431 x 344 x 83mm and 9.0kg, the A25+ maintains a somewhat more compact chassis than the A15+ despite greater output power.

Sound and use context

Expect a genuinely accomplished amplification character reflecting the exceptional 106dB signal-to-noise figure combined with the considerably greater 165W-into-4-ohms output, representing Arcam's more accomplished current engineering above the A15+.

Pairing

The built-in Bluetooth and Auracast connectivity covers wireless audio sources directly without needing a separate outboard receiver.
