RMS is really just a way to quantify an alternating current, as you know. If you say a device is guaranteed to develop 500Wrms without damage, then you can know how much current output can be safely delivered. But you don't know anything about signal quality; It may be way into clipping at this level. The EIA standard describes the power level when the device reaches 1% total harmonic distortion.
