I'm stuck on which of these to choose from. They both are priced about the same. The Onkyo is 75 watts per channel and the Pioneer is 100 watts per channel. 100 watts is all my speakers can nandle so I have narrowed it down to these 2. I like the Automatic MCACC feature on the Pioneer. Makes set up a snap. I am gonna wait till I hear what all of you think before making my decision. Its what I usually do anyway.
The Onkyo 503 is a much superior receiver,both performance & build-wise.The 25 WPC difference is meaningless.
