The C 368 BluOS-2i is a streaming integrated amplifier by NAD that delivers 80 watts x 2 channels into 8 ohms and 80 watts x 2 channels into 4 ohms. It was released in 2019. It is a 2-channel design using a Class D output stage. Bridged to mono it delivers 300 watts x 1-channel (@ 20-20kHz, into 8Ω, at 0.03% THD), which is the usual way to use a pair of these on a demanding speaker. 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 NAD C 368 BluOS-2i has an MSRP of $1,749.
There are 10 NAD amplifiers in our database. Below you can see the main specs of these amps.
NAD 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 NAD C 368 BluOS-2i is rated at 80 watts RMS into 8-ohms. NAD provides this wattage at a THD (Total Harmonic Distortion) of 0.03% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 80 watts into 8-ohms (20 Hz-20 kHz) at 0.03%
- 80 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 98dB Signal to Noise Ratio

Which speakers suit the NAD C 368 BluOS-2i?
80 W into 8 ohms, 80 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current

Need more power?
NAD C 368 BluOS-2i is rated at 80 watts into 8 ohms, which puts it in our 61 to 90 watts band. The next band up is 91 to 120 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.
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 Up to 60 watts band and better speakers.
When pairing the NAD C 368 BluOS-2i 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 NAD C 368 BluOS-2i Amplifier good for?
