The cheapest features a discrete-component output stage, while the most costly offers up support for three zones, Spotify streaming, and plenty more.
Onkyo’s latest additions to its receiver line may be on the lower end of the price spectrum, but they offer quite a bit of functionality for the cost.
The TX-NR616 ($699) is at the top of the line for these new receivers and gives you 7.2 channels of THX Select2 Plus certified audio. It streams from online sources like Spotify and MP3tunes and even packs video scaling up to 4K if you’ve got a display to match.
If you’re willing to sacrifice a bit of power and a third zone out, the NR515 does much of the same for $599. The price drops even further if you’re willing to accept the 5.1 channels offered by the NR515.
The most bare-bones receiver from Onkyo is the TX-SR313, which comes in at $299. It drops many of the features of it bigger brothers, but still shirks the cheaper integrated amplifier in favor of a discrete-component output stage.
