Arcam A15+

Strategic circuit tweaks improve an already excellent performer

- 

Arcam’s Radia range of stereo products was introduced only back in 2023. In these two short years, it has become something of a cornerstone of our affordable hi-fi recommendations. We have a particularly soft spot for the A5 and A15 integrated amplifiers, which both combine a comprehensive feature-set with class-leading sound quality.

So, when we hear that the company is introducing upgraded versions of these amplifiers, we can't wait to have a listen.

We shouldn't get too carried away here as regards the scale of the upgrades. There have been no massive revisions or significant specification changes. Think of it as a gentle bit of fettling of an already accomplished product. How gentle? Without the badging, it would be hard to notice anything had changed. Unless you listened, of course.

Build quality remains the same as for the previous generation - that is, solid and well finished. We still like the clean, modern look, though we now think that the two large control dials could feel a little more substantial and positive in use.

While the step-up A25+ model has been given a crisper display, the one fitted to the A15+ remains frosted as before, and so could be sharper. The partnering remote is a simple, plastic affair that does the job well enough.

This '+' version remains a well-equipped amplifier that should slot into pretty much any price-compatible stereo system with ease. It thoughtfully adds an HDMI eARC digital input alongside the previous generation's optical and a pair of coaxial inputs.

Fans of analogue aren't ignored, with the original's moving-magnet phono input and trio of line-level analogue connections continuing. As before, there is a preamplifier output for those who want to upgrade and a 3.5mm headphone socket on the front.
