Overview
Compact and built for a handful of sources, the Onkyo TX-NR5100 is an 80-watt AV receiver with 4 HDMI ports and Bluetooth connectivity for a smaller home theater setup.
Four HDMI inputs cover a modest source lineup, a console plus a streaming box and a disc player for example, without the higher port counts found on larger receivers. Bluetooth is the only wireless connection listed, with no Wi-Fi noted, so streaming from a phone works but network-based casting is not part of this spec sheet.
- 80W AV receiver

Who it's for
Fits a simple home theater setup with a small number of HDMI sources and no need for a wired multi-room network connection. Buyers wanting a high HDMI count or Wi-Fi streaming should look elsewhere in Onkyo's lineup.
