[ZIPPO]

The Marantz SR6003 is the step up model of the SR5003, these are it's power rating results.
The Marantz SR5003 will probably test similar.

Power output from the Marantz SR6003 A/V receiver was very impressive. It substantially beat its 100-watts-per-channel ratings in single-channel, stereo, and even 5-channel tests (rare for any receiver), and it very nearly managed 100 watts all around even with all 7 channels driven. Frequency-response and distortion tests gave uniformly excellent results as well. But noise and linearity results consistently fell a bit short of theoretical targets, factors that together suggest a moderate least-significant-bit error in the digital-to-analog conversion system. Although this would restrict ultimate dynamic range by a few dB, it’s almost sure to be undetectable in real-world listening, and I noted no such artifacts in my evaluations, including fade-to-noise audibility tests over headphones.
