What is the real power output of the nc502mp at 8 and 4 ohms? On the Hypex website they are measuring the power at 1khz only.
You have to look at the data sheets. They provide distortion vs. power at 100, 1000, and 6000 Hz.
Measured the way amps are traditionally measured (power at specified distortion across the band), I interpret their data to mean about 220 wpc into 8 ohms and 440 wpc into 4 ohms. “Peak” power is measured at 1% distortion, and as I recall that’s in the 350/600 range.
