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 HiFi Rose RS520 is rated at 250 watts RMS into 8-ohms. HiFi Rose provides this wattage at a THD (Total Harmonic Distortion) of 0.007% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 250 watts into 8-ohms (10-85k) at 0.007%
- 250 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 109dB Signal to Noise Ratio
When pairing the HiFi Rose RS520 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.
