Above are photos of the Onkyo TX-SR503 Entry-Level Receiver (left) and the Pioneer VSX-82TXS High End Receiver (right). The images are not to scale. Although both Receivers are the same width and approximately the same depth, the Pioneer VSX-82TXS, pictured on the right, is about twice the height, and about twice as heavy, as the Onkyo TX-SR503, pictured on the left.
You will notice, on the bottom right of the Onkyo, there is a Composite video input and a set of analog stereo inputs on the front panel. On the bottom left of the Onkyo is a Headphone Jack.
In addition, the Pioneer has a flip-down front panel door that houses additional controls (not shown in the photo), as well as set of both Composite and S-video connections, and both a Digital Optical and analog stereo inputs. In addition, the front panel also hides a Headphone Jack.
