Cambridge Audio Edge A integrated amplifier

Cambridge Audio Edge A

My only regret with the Edge A is a local one. The amplifier deserves to do well everywhere, and, in most places, it will tear a lot of the opposition apart. But possibly not in the UK. Why? Because Cambridge Audio is sold through Richer Sounds stores. There’s nothing intrinsically wrong with that – quite the reverse in fact, as Richer has some of the best trained and most enthusiastic store staff in the audio business and many of the specialist dealers could do well to follow the company’s lead here – but Richer has a distinct clientele and client base… and it isn’t the kind that is known for dropping £4,500 on an amplifier. It’s a high-street specialist and that dictates its own price ceiling. The snobby UK audiophile might never walk into a Richer Sounds store as a result, and they will miss out on a real beauty in the shape of the Cambridge Audio Edge A.

The fact I want more people to enjoy the Edge A is a mark of how good an integrated amplifier Cambridge Audio has built here. Cambridge Audio has long held a reputation for making affordable giant killers. In its 50th year, it made its own giant, and even that is still a giant killer in its own right. Although there are amplifiers that bring their own sense of musical taste to the audio party, one has to think in many respects spending vastly more on your amplifiers is sometimes more to do with vanity and brand than pure sonic benefit. If you think there’s a law of diminishing returns in high-end, Cambridge Audio is its leading Edge.
