Onkyo TX-SR373 review
Two models from Onkyo deliver the same figures in power output. Both have 135/6 W/Ohm. The 373 unit has 5.1 channels, 383 owns 7.2. Nevertheless, it has the most necessary. Four HDMI inputs and one output with support for audio return channel will allow you to connect several of the most modern compatible sources to a TV or projector using one HDMI cable. These interfaces allow 4K Ultra HD video with extended dynamic range (HDR) and content protection over HDCP 2.2, and Dolby TrueHD and DTS-HD Master Audio decoders provide full-fledged playback of movie soundtracks. Thus, in terms of technology, the TX-SR373 is not far behind the leaders of the Hi-Fi industry. 
Onkyo TX-SR383 review
The device is equipped with four HDMI inputs with HDCP 2.2. There is also an HDMI output with ARC. You can use the CEC interface automation functions to turn on the sound synchronously with the TV on. In addition to HDMI, the TX-SR383 has a composite video input, optical and coaxial audio inputs. In addition, the device was equipped with standard analog RCA connectors for audio. If we talk about wireless switching, then the novelty received a Bluetooth module (aptX). Of the functions not related to watching movies, broadcasts or games, it has Bluetooth (version 3.0) and a USB port (type A) on the front panel.
