ONKYO TX-NR5100 (USED)

Onkyo TX-NR5100 7.2-Channel 8K AV Receiver (Open Box) An open box Onkyo TX-NR5100. Please note that no factory warranty applies. The TX-NR5100 is Onkyo's capable mid-range 7.2-channel AV receiver, built around the brand's DAA (Discrete Amplifier Architecture) — a custom high-current low-noise power transformer, customized capacitors, and discrete output stages carefully tuned to prevent phase shift and deliver 80 watts per channel with genuine dynamic headroom. Dolby Atmos, DTS:X, Dolby Atmos Height Virtualizer, and DTS Virtual:X are all supported, enabling immersive 3D audio in up to a 5.2.2-channel configuration with any speaker layout. On the video side, four HDMI 2.1 inputs support 8K/60Hz and 4K/120Hz passthrough with HDR10+, Dolby Vision, ALLM, VRR, and QFT — making it equally at home in a high-end home theater and a next-generation gaming setup. HDMI eARC simplifies TV connectivity while supporting lossless audio formats directly from connected displays. AccuEQ automatic room calibration handles speaker distance, level, and crossover setup with ease. Streaming is handled via dual-band Wi-Fi, aptX HD Bluetooth, Apple AirPlay 2, Google Cast, and DTS Play-Fi for multi-room audio, with built-in access to Spotify, Tidal, Deezer, TuneIn, and Pandora. The receiver also integrates with Amazon Alexa, Google Assistant, and Apple Siri for voice control, and is Works With Sonos certified for seamless integration into existing Sonos ecosystems. A MM phono input, Pure Direct mode, Zone 2 output, and Klipsch Optimize Mode for plug-and-play Klipsch speaker integration round out a thoroughly versatile feature set.
