The Nero Stream XD2 is a streaming integrated amplifier by OSD that delivers 60 watts x 2 channels into 8 ohms and 120 watts x 2 channels into 4 ohms. It was released in 2021. 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 (Cirrus Logic CS8416), so you can play digital sources directly with no separate DAC unit needed. The OSD Nero Stream XD2 has an MSRP of $400.
There are 3 OSD amplifiers in our database. Below you can see the main specs of these amps.
OSD 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 OSD Nero Stream XD2 is rated at 60 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 60 watts into 8-ohms
- 120 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 OSD Nero Stream XD2?
60 W into 8 ohms, 120 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
OSD Nero Stream XD2 is rated at 60 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 OSD Nero Stream XD2 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.
