I like to know what the difference is between the TX-SR502 from the TX-SR503 Onkyo a/v receiver??

Check Onkyos website www.onkyousa.com . The last time I looked it was an additional channel plus a 192/24 DAC.

Plus, they also eliminated the S-video front panel input, and the B speaker terminals are now spring clips instead of binding posts.
