The Uniti Atom is a streaming integrated amplifier by Naim that delivers 40 watts x 2 channels into 8 ohms. It was released in December 2016. It is a 2-channel design using a Class A/B output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC (Burr Brown), so you can play digital sources directly with no separate DAC unit needed. The Naim Uniti Atom has an MSRP of $3,799.

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 Uniti Atom is rated at 40 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 40 watts into 8-ohms (20 Hz-20 kHz)
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Which speakers suit the Naim Uniti Atom?
40 W into 8 ohms, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Naim Uniti Atom is rated at 40 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB 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.
When pairing the Naim Uniti Atom 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.
