The Audio Evo 150 SE is a streaming integrated amplifier by Cambridge Audio that delivers 150 watts x 2 channels into 8 ohms and 250 watts x 2 channels into 4 ohms. It was released in July 2025. It is a 2-channel design using a Class D 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. It also has a phono input, so a turntable can connect straight to it. The Cambridge Audio Evo 150 SE has an MSRP of $3,299.

Cambridge Audio Integrated Amplifier Series
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 Evo 150 SE is rated at 150 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 150 watts into 8-ohms (20 Hz-20 kHz)
- 250 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Cambridge Audio Evo 150 SE is rated at 150 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB 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.
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 91 to 120 watts band and better speakers.
When pairing the Cambridge Audio Evo 150 SE 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.

Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Cambridge Audio Evo 150 SE features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
Balanced connections
Cambridge Audio Evo 150 SE has a balanced XLR input. 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 Evo 150 SE's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC.
Cambridge Audio Evo 150 SE Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓150 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Class D output stage, so it runs cool and wastes little power as heat - which is how it fits in a small case.
- ✓Built-in DAC handling 32-bit / 384 and DSD, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 2 optical, 1 coaxial and USB.
- ✓Phono stage built in (MM), so a turntable needs no separate preamplifier.
- ✓Streams over the network without a separate streamer: Spotify Connect and Tidal; AirPlay 2, Chromecast built-in and Roon.
- ✓Bluetooth (version 4.2) for playing straight from a phone.
- ✓Pre-outs (Yes) leave room to add a power amplifier or an active subwoofer later.
- ✓Dedicated subwoofer output (Single).
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Headphone output (3.5mm).
- ✓Detachable mains lead (IEC 3-prong).
- ✗The phono stage is moving-magnet only; a moving-coil cartridge would need a step-up or an external stage.
