The C 3050 BluOS-D is a Streaming Integrated Amplifier by NAD that delivers 100 watts x 2 channels into 8 ohms and 100 watts x 2 channels into 4 ohms. It was released in May 2023. Minimum impedance of 4 ohms makes the C 3050 BluOS-D compatible with a wide range of loudspeakers. Thanks to its built-in Texas Instruments TI PCM5242 DAC, you can play digital sources directly without the need for an external DAC unit. NAD C 3050 lets you connect your turntable via its Phono input and start listening to your vinyl collection without a hassle. NAD C 3050 has an MSRP of 1899$ but can often be found around 1799$.

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 3050 is rated at 100 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:
- 100 watts into 8-ohms (20-20k) at 0.03%
- 100 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 95dB Signal to Noise Ratio

Which speakers suit the NAD C 3050?
100 W into 8 ohms, 100 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the NAD C 3050 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.
