In general, you should be fine ... just don't drive the Onkyo 502 and its rather minor 55 wpc (at best) to the clipping (distortion) point.
As HT receivers go, the basic Onkyo is a well made, well engineered little receiver (I owned its great grandfather the 434X), that is OK for music. It may not be an MF 300 (I own one of them also) in terms of finesse, but it is nothing to be ashamed of. Note: just make sure to set your Onkyo correctly up as a 2 channel receiver.
