- Bluetooth 5.4 with Auracast and APTX -TOFSFRE
- Upgraded circuits, refined components and intelligent power control
- Three models: $ 1,199, $ 1,499 and $ 1,999
Arcam has launched three new integrated amplifiers in the Radia series: A5+, A15+and A25+. As the names suggest, the upgraded versions of the impressive A5, A15 and A25 are the iconic sound company launched in 2023.
There are three key upgrades here: Upgraded circuits including Arcam’s latest Bluetooth platform; refined components; and intelligent power control.
The 2025 versions of the A15 and A25 also add HDMI EARC, and if you are plumping for the A25+, you also get a precision-cut glass front panel designed to supplement Arcam’s A25 streamer.
Arcam A5+, A15+and A25+: Key features and pricing
All three amplifiers now have Bluetooth 5.4 with Auracast, APTX -Tabs -free and support for Snapdragon sound.
A5+ has 2 x 50W class AB current and a tuned mm phono phase, and the more powerful A15+ sets the effect for 2 x 80W.
The 2 x 100W class G-driven A25+ gets the biggest update of the series, including a new transformer. This has a dedicated winding to the digital and DAC circuits, double linear regulation in the analog power supplies and improvements to its power and main center to lower its impedance and improve overall clarity.
The A25+ also gets an ESS9018 DAC dedicated to its SPDIF inputs, a USB-C input and an OLED screen behind that glass panel.
The A15+ also gets a transformer upgrade, while the A5+ has improved components that reduce PCB interference and lower the power supply impedance.
All three amplifiers are improvements over their predecessors, but these improvements come at a higher price – presumably because of at least partially partly and potential US tariffs. Where A5, A15 and A25 were launched in the US for $ 699, $ 999 and $ 1,499, the new A5+, A15+ and A25+ $ 1,199, $ 1,499 and $ 1,999. Prices for other countries have not been announced yet.
All three amplifiers debut at CEDIA EXPO this month (September 2025) and will be sent at the beginning of Q4 2025.
