Overview
The Onkyo TX-SR373 is a 155 watt AV receiver with four HDMI ports, Bluetooth, and a black chassis measuring 14.5 x 17 x 13.38 in and weighing 17.6 lb.
Onkyo's SR series targets buyers building a full home theater rather than a simple speaker amp, and the four HDMI inputs reflect that: enough to connect a game console, streaming box, and cable source at once. Bluetooth adds wireless audio streaming on top of the wired HDMI switching.

Who it's for
Suited to anyone connecting multiple HDMI sources, such as a console, streaming device, and disc player, through a single receiver. Less useful for a setup with only one or two devices, where the four port switching is not needed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Four HDMI ports for source switching
- Bluetooth wireless audio
- 155 watt rated power
- 17.6 lb, heavier than a compact unit
- Power rating modest for larger rooms
Performance notes
HDMI switching lets the receiver pass video through to the display while handling audio decoding for each connected source, which is the main job of a unit like this. The 155 watt rating covers a standard speaker setup at moderate listening levels rather than a large room.
