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 PS Audio Stellar Strata MK2 is rated at 100 watts RMS into 8-ohms. PS Audio provides this wattage at a THD (Total Harmonic Distortion) of 0.02% at 1kHz, 10W into 4 ohms 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 at 0.02% at 1kHz, 10W into 4 ohms
- 150 watts into 4-ohms
