Here is an Oppo 203 review

Around the back is a hugely impressive selection of ports. You get two HDMI outputs (one 1.4 for audio only and the other 2.0 for video and audio) and a single HDMI 2.0 input with HDCP 2.2, so you can hook up a Chromecast or Amazon Fire Stick to add smart features.

There are optical and coaxial digital audio outputs, a pair of USB 3.0 ports for connecting hard disks and thumb drives and eight phono output ports for surround sound connection to older home theatre receivers.
