      Powerfully Subtle

      For all its power, Edge W is remarkably detailed. The sound is finely balanced, with a musical depth and clarity that comes through with every note. It’s all down to how we chose the componentry inside – nothing was picked on price, specs or measured performance. We listened carefully and created our system with components that simply sounded the best. The end result is a power amplifier that truly brings an original recording to life like no other.

      Just 14 Components in the Signal Path

      Although minimal in its exterior design, Edge W has some complex audio engineering inside. To remove the barriers between you and your music, we have worked hard to minimise the number of components in the signal path. As a result, Edge W delivers a more faithful reproduction of the original recording; an impressively detailed three-dimensional sound, with striking staging and focus.


      More Musical Detail

      We pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge we 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 W. Instead we 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.

        'Cambridge Audio has surpassed itself with the Edge NQ/W combination... lovely to look at, nice to use and packed to the gunwales with features.'

        Germany, December 2018

        „Die Kette besitzt eine geradezu unerhörte Musikalität, die nicht nur bei zackig-dynamischem Material zur Geltung kommt. Sie verleiht auch leisen Aufnahmen Charakter, Schwung und Seele.“
      • Fidelity

        Germany, December 2018

        'We never doubted for a moment that Cambridge Audio can meet the demands of the high-end class. The components of the 851 series already show how much flair for musicality and balanced tonal balance the British have developed. But the Edge combination offers much more than that.'
