"Cambridge Audio has always represented great value and produces products that punch well above their weight. Cambridge Audio's Edge A is no exception. The simplicity of styling and operation are outstanding and fresh in a copy-cat kind of world. It is a well thought out package and is in step with modern needs. But it's the sound quality that really has me excited. It delivers sound the way that I prefer, with enthusiasm, youthfulness, dynamic expression and musicality that only genuinely great products deliver. It's fun to listen to and begged me to keep playing a little longer.

With 50 solid years under its belt, Cambridge Audio is a company firmly set on remaining here for another 50. It will take precisely this type of 'outside of the box' thinking to draw new customers their way. The Edge A is excellent value for money, and I dare say there's not a better sounding integrated amplifier at the asking price. I tried to find one but couldn't, and that's why I'm buying the review sample for myself: a well-deserved Applause Award recipient and an unquestionable recommendation."

Breath-taking musicality

Edge A is designed to bring musical detail to life. It delivers a finely balanced sound with depth and clarity that comes through with every note. Cambridge Audio developed the system by ear, testing every component and only choosing those that blew them away. The end result is a ground-breaking arrangement that produces a much cleaner signal path and lets your music breathe. Edge A perfectly delivers Cambridge Audio's classic British sound – nothing added, nothing taken away.

More musical detail

Cambridge Audio pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge they take this one step further, using opposing symmetry twin toroidal transformers. This cancels out electromagnetic interference whilst offering outstanding power and maintaining consistent tonality, no matter how loud it’s played.

Effortless power without distortion

Using standard Class A amplifier technology wasn’t going to be efficient enough for Edge A. Instead, Cambridge Audio added a bias voltage to a traditional Class AB design, reducing distortion to inaudible levels. This unique configuration also produces less heat and makes the whole system much more effective.

Hi-res Bluetooth

Pair any Bluetooth device to your Edge A to easily stream your music. With aptX HD support, you can play your audio at up to 24-bit/48kHz quality for an incredibly rich listening experience.

Sonic balance

Edge A was designed with a unique Printed Circuit Board (PCB). Cambridge Audio's engineers replaced conventional capacitors with a DC-coupled topology and also added a solid-state volume control. The end result is a clean signal path that’s perfectly balanced at any volume.

Edge Series - British sound personified

In the build-up to Cambridge Audio's 50th anniversary, they asked their engineers a simple question – what would they make if anything was possible? Forget cost. Forget limitations. Create a system that delivers previously undiscovered layers of detail, is highly transparent, offering superlative sound-staging. A product true to Cambridge Audio’s foundations of creative innovation and entrepreneurial ambition. Over 3 years in the making, utilising a team of 9 engineers, the result is Edge.

In recognition of their heritage, Cambridge Audio developed Edge, the embodiment of their signature Great British Sound and the pinnacle of 50 years of Hi-Fi expertise. Beautifully minimal in its design, each component has a curved extruded aluminium front and floating top plate. It’s an extraordinary exterior that’s hiding some extraordinary audio engineering inside.

Let the music through

To remove the barriers between you and your music, Cambridge Audio have worked hard to minimise the number of components in the signal path in the Edge series. As a result, Edge delivers a more faithful reproduction of the original recording; an impressively detailed three-dimensional sound, with striking staging and focus.

The inside edge

Cambridge Audio only ever choose components for their sonic merits – not price, not specs, nor measured performance. This ‘listen first, measure later’ ethos means blind-auditioning all price and performance levels and only going with those that sound the most dynamic, give the greatest presence, offer a revealing clarity; in short, the most musical.

Complex simplicity

Gone are the rows of buttons and dials you often see on high-end audio kit. Instead, the Edge Series features one high-quality dual concentric volume and source select control knob, enabling you to navigate menus and control the volume with a simple twist. Designed and assembled in the UK, this mechanical marvel comprises 31 precision-milled engineered parts. The complexity inside enables the most intuitive and purest of interfaces.
