What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our summary
Product Strengths
- Pleasant, smooth, and relaxed playback
- More insight and tightness in the music
- Much insight into sound and musical structure
- A fresh and modern-looking product with a clean and unfussy exterior, which looks simple yet elegant
- Manages a difficult balancing act superbly—forgiving enough not to emphasise the shortcomings of limited partnering equipment, yet still having the insight and transparency to make the most of more capable signals
Product Considerations
- The front panel display lacks crispness due to the 'frosted' finish
- The speaker terminals don't offer a great deal of space
- The back panel itself shows a certain amount of flexibility, which is a little worrying in terms of longevity
- The power on paper is a little optimistic
Comparisons (according to reviewers)
- Vs Atoll IN50: The Atoll plays a bit bigger, but Arcam gives more insight and tightness
- Vs Cambridge Audio Azur 840A: The Arcam A5's midrange and voice reproduction that the Cambridge just couldn't quite match
Takeaway: The Arcam A5 is a well-rounded performer that plays music enjoyably without getting in the way and is affordable, feature-rich and uncomplicated. It is a great amp for someone looking for a balance of performance and features.
