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. THD (Total Harmonic Distortion) at this wattage is also an important indicator of distortion (lower THD is better) but unfortunately OSD doesn't provide this value.

Here are the main highlights of its performance specs:

  • 60 watts into 8-ohms (1k)
  • 120 watts into 4-ohms
  • 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
  • 95dB Signal to Noise Ratio

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.
