How Arcam Evolved Its Legendary Amplifiers with Cutting-Edge Sound Tech

Arcam elevates its iconic amplifiers with Bluetooth 5.4, enhanced circuitry, and smart power management for a sonic experience that’s pure magic.

The Sound Evolution You’ve Been Waiting For

If you’re anything like me, a true audiophile who cherishes rich, refined sound, then Arcam’s latest moves are thrilling news. The British audio legend has just unveiled upgraded versions of its beloved Radia series amplifiers — the A5+, A15+, and A25+. These aren’t just simple refreshes; they’re a sonic evolution, blending classic warmth with modern tech wizardry.

I remember the first time I heard an original Arcam A25—it was like the music came alive in the room, every note dripping with clarity and passion. Now, with these new releases, Arcam is upping the ante in a big way.

What’s New in the Radia Series?

Three major ingredients have been mixed into this sonic recipe:

• Bluetooth 5.4 with Auracast and aptX Lossless: Streaming high-res audio wirelessly just got a whole lot sweeter.
• Refined circuitry and upgraded components: Layered improvements ensuring a cleaner, more dynamic soundstage.
• Intelligent power management: Smarter energy use means efficiency without sacrificing power or warmth.

These upgrades are no small tweaks; they represent a thoughtful re-engineering of the amplifiers’ core.

Bluetooth 5.4 and Auracast: Wireless Audio at Its Finest

One of the standout new features across all three amps is the adoption of Bluetooth 5.4. This latest standard comes with Auracast technology and aptX Lossless support, meaning you can enjoy your favorite tunes in crystal-clear quality without being tethered by cables. Plus, with Snapdragon Sound compatibility, these amps are ready for the highest standards of wireless audio fidelity.

From personal experience, wireless audio is often compromised for convenience, but Arcam's approach feels like the best of both worlds: impeccable sound with no strings attached.

Meet the Trio: A5+, A15+, and A25+

The new lineup offers something for every audiophile’s budget and power needs:

• A5+: Packing 2×50 watts of class AB power, this model also boasts a finely tuned MM phono stage for vinyl lovers.
• A15+: Amplifies the power to 2×80 watts, perfect for larger rooms or more demanding speakers.
• A25+: The flagship with 2×100 watts of Class G power, featuring the most extensive upgrades including a new transformer and specially isolated windings for digital and DAC circuits.

It’s the A25+ that steals the spotlight with features like dual linear regulators in the analog power supply, and enhanced filtering that lowers impedance and polishes the sound purity. This model also flaunts an ESS9018 DAC dedicated to SPDIF inputs, a USB-C input, and an elegant OLED display behind a precision-cut glass front panel that pairs beautifully with the Arcam A25 streamer.

Behind the Scenes: Circuitry and Components

The A15+ also benefits from a transformer upgrade, while the A5+ shines with improved components that reduce interference on the PCB and lower power supply impedance.

It’s clear that Arcam’s engineers have taken a holistic approach—enhancing every layer from hardware to software to deliver an experience that’s both powerful and nuanced.

Pricing and Availability

With these upgrades come higher prices, reflecting the cutting-edge tech inside:

The new models made their debut at the CEDIA Expo in September 2025 and are expected to hit the market in early Q4 2025.
