The CI-Uniti 102 is a streaming integrated amplifier by Naim that delivers 150 watts x 2 channels into 8 ohms, 260 watts x 2 into 4 ohms. It was released in February 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. The Naim CI-Uniti 102 has an MSRP of $1,799 but can often be found around $1,499.
There are 7 Naim amplifiers in our database. Below you can see the main specs of these amps.
Naim 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 Naim CI-Uniti 102 is rated at 150 watts RMS into 8-ohms. Naim provides this wattage at a THD (Total Harmonic Distortion) of under 0.006% at 1kHz which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 150 watts into 8-ohms at under 0.006% at 1kHz
- 260 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 110dB Signal to Noise Ratio

Which speakers suit the Naim CI-Uniti 102?
150 W into 8 ohms, 260 W into 4, rated down to 4 ohms.

Need more power?
Naim CI-Uniti 102 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 Naim CI-Uniti 102 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 Naim CI-Uniti 102 Amplifier good for?

Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Naim CI-Uniti 102 supports the following Bluetooth Codecs when used with supported devices:
Phono Input
Naim CI-Uniti 102 doesn't have a phono input so in order to play your vinyl albums, Naim CI-Uniti 102 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
Naim CI-Uniti 102 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).

Powered Subwoofers page to find a subwoofer that will work with Naim CI-Uniti 102 amp and your speakers.
DAC and Digital Music
The Naim CI-Uniti 102's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC.
Naim CI-Uniti 102 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 150 watts into 8 ohms rising to 260 into 4, which points to a power supply with real current in reserve.
- ✓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.
- ✓Signal-to-noise ratio of 110dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.006%, an order of magnitude below what is generally held to be audible.
- ✓Built-in DAC handling 32-bit / 384, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Streams over the network without a separate streamer: AirPlay 2 and Chromecast built-in.
- ✓Bluetooth (version 5.1 and SBC, AAC) for playing straight from a phone.
- ✓Pre-outs (Stereo RCA) leave room to add a power amplifier or an active subwoofer later.
- ✓Dedicated subwoofer output (Stereo RCA, can be configured for subwoofers or sub-zones).
- ✓At 300mm wide it fits where a full-size component will not.
- ✓App control (Focal & Naim).
- ✓Detachable mains lead (IEC 3-prong).
- ✗Only 1 analogue input, so a second source means unplugging the first.
