The Edge A is an integrated amplifier with built-in DAC by Cambridge Audio that delivers 100 watts x 2 channels into 8 ohms and 200 watts x 2 channels into 4 ohms. It was released in September 2018. It is a 2-channel design using a Class XA output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC, so you can play digital sources directly with no separate DAC unit needed. The Cambridge Audio Edge A has an MSRP of $6,499.

Performance Specs

One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Cambridge Audio Edge A is rated at 100 watts RMS into 8-ohms. Cambridge Audio provides this wattage at a THD (Total Harmonic Distortion) of 0.02% which is an important indicator of distortion at the given values (lower THD is better).

Here are the main highlights of its performance specs:

  • 100 watts into 8-ohms (3 Hz-80 kHz) at 0.02%
  • 200 watts into 4-ohms
  • 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
  • 103dB Signal to Noise Ratio

Which speakers suit the Cambridge Audio Edge A?

100 W into 8 ohms, 200 W into 4, rated down to 4 ohms. We rank every passive speaker we cover against it on power, impedance safety and current delivery.

We check power, impedance safety and current delivery - not just watts.

Need more power?

Cambridge Audio Edge A is rated at 100 watts into 8 ohms, which puts it in our 91 to 120 watts band. The next band up is 121 to 180 watts, which is worth about 1.5dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.

  • Advance Paris NOVA A-i130 – 125 watts, $6,499 compare
  • Primare I35 Prisma – 150 watts, $5,795 compare
  • Arcam SA45 – 180 watts, $5,500 compare

Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 61 to 90 watts band and better speakers.

When pairing the Cambridge Audio Edge A with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels. Operating your amp outside of this max range may damage the speakers.


What size of room is the Cambridge Audio Edge A Amplifier good for?

An essential deciding factor is the size of the room in which you intend to employ the Cambridge Audio Edge A amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Listening Environment Suitability

Cambridge Audio Edge A supports the following Bluetooth Codecs when used with supported devices:

  • AptX HD

Phono Input

Cambridge Audio Edge A doesn't have a phono input so in order to play your vinyl albums, Cambridge Audio Edge A has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.

Subwoofer Output

Cambridge Audio Edge A has Stereo RCA preamp outputs which can be used to connect to a powered subwoofer via an RCA cable ( as long as your sub supports this connection).
Check our Powered Subwoofers page to find a subwoofer that will work with Cambridge Audio Edge A amp and your speakers.

Balanced connections

Cambridge Audio Edge A has balanced XLR connections on both its input and its output. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.

DAC and Digital Music

The Cambridge Audio Edge A's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC.

Cambridge Audio Edge A External Dimensions and Weight

Cambridge Audio Edge A has external dimensions of (H x W x D) 5-15/16inch x 18-1/8inch x 15-15/16inch (151.0mm x 461.0mm x 405.0mm ). The unit weighs 24.41 kg (53.7 lbs).
