The ARCAM A25+ is the most ambitious and versatile integrated amp in the Radia+ range, designed for listeners who want real authority, dynamics and modern connectivity in a stereo system. Rated at 100 W per channel into 8Ω and 165 W per channel into 4Ω (per manufacturer), it delivers the control and headroom needed for more demanding loudspeakers, while staying clean and musical even at higher volumes.
A key highlight is ARCAM’s 5th‑generation Class G amplification, known for combining efficiency with strong current delivery and dynamic response. In practice, this can mean tighter bass, stronger attack and an effortless feel when the music gets energetic. ARCAM also upgrades the platform with an enhanced power supply, a new DAC, and a very flexible input set.
For TV integration, HDMI eARC makes the A25+ a serious alternative to soundbars, while keeping true hi‑fi stereo sound. For computer use and high‑resolution playback, the USB‑C input supports higher sample rates than other digital inputs. And for everyday wireless listening, you get Bluetooth 5.4 with Snapdragon Sound (including aptX Lossless) plus Auracast, enabling audio sharing to multiple compatible devices.
Vinyl is covered too, thanks to a carefully tuned MM phono stage. If you want an integrated amp that can be the system’s hub—music, TV and digital sources—with top performance within the Radia+ line, the A25+ is a premium pick.
