Arcam A25+ Integrated Amplifier

A 100 Wpc class-G amp with HDMI eARC, Bluetooth, a phonostage, and wired or wireless headphone capability.

Amplification is Arcam's core competence, and the A25 is the latest in more than 45 years of amplifier design and manufacture. Now, the A25+ adds HDMI eARC, Bluetooth 5.4 with aptX Lossless, and a transformer redesign that lowers noise.

A 5th generation class-G amplifier design offers the best sound quality and dynamics from what has always been a better sounding, and more efficient class of amplifier. 

In addition to carefully selected hi-fi components, the A25+ comes with a modern convenience that lets you play music straight out of the box: Bluetooth capability. The latest Radia “+” models introduce a major update to Bluetooth performance.

Built on the new Bluetooth 5.4 platform, they add support for LE Audio with the LC3 codec for cleaner, more efficient wireless sound, along with next-generation features such as Auracast for shared listening and broader device compatibility. They also include aptX Lossless for true CD-quality streaming from supported devices. This upgrade significantly improves wireless sound quality, reduces latency, and future-proofs the amplifier for the growing ecosystem of LE Audio headphones, earbuds, and assistive-listening products.

An HDMI eARC connection means you can now use your Arcam for TV sound, enhancing your gaming and movie-watching experience.

In addition, special to the A25+ is a USB-C input for a computer-based streamer, whether an Apple, PC, or Raspberry Pi.

For optimum sound quality, you can upgrade to the separate, matching Arcam ST5 streaming DAC that has a special connection just for the A25+. 

There is also a high-quality onboard phonostage to ensure your records sound as lush and engaging as possible.
