Hi-Fi Performance from a Compact Body

Onkyo’s in-house-developed Switching Amplifier technology delivers high power with vanishingly low distortion from a physically small receiver. Powered by a custom transformer and huge audio capacitors, the discrete modulation stage delivers exceptionally clear and musical sound, even with difficult-to-drive or sensitive speakers.

Super-Rigid Construction Reflects a Premium Build

The amp system and audio circuit boards are housed in a rigid, 1.6 mm-thick full-flat metal chassis further stiffened by a solid aluminum faceplate. Together with anti-resonant insulator feet, vibrations that cause interference on audio signals are virtually eliminated, improving clarity.

Stream Music from Mobile and PC 

Chromecast built-in* and AirPlay included on the receiver let you stream audio from a variety of supported applications for iPhone, iPad, and Android™ devices (as well as Mac, Windows®, and Chromebook™ computers) in seconds. Bluetooth® wireless technology is also included.

* Service enabled via firmware update.

On-Demand Music Streaming  

Support for TIDAL, Deezer, and TuneIn is built into the receiver. Use the Onkyo remote app to select a service and stream essentially any music you want, or stream directly from the Spotify® application.

Select, Play, and Update Music Stored on a Connected HDD

Load your entire digital library onto an HDD*, connect it to one of the receiver’s USB inputs, and use our smartphone app to browse and play anything in your collection complete with album art and song information. A future firmware update will enable full music server capability with audio files writable to HDD via personal computer.

* HDD must be formatted to FAT32. Onkyo cannot guarantee, nor has tested for, correct operation with all HDD device types and brands.  

Hi-Res Audio via Network or USB

The R-N855 receiver features a premium AK4490 768 kHz/ 32-bit DAC to convert digital signals into a smooth analog waveform. This DAC module is renowned for high bandwidth and low noise, and decodes 11.2 MHz DSD and 192/24 PCM Hi-Res Audio formats over network or USB. 

VLSC™ Reduces Noise and Reveals Detail

Pulse noise arises when converting digital signals to analog. The R-N855 features VLSC (Vector Linear Shaping Circuitry), a unique technology that analyzes input and output signals and erases noise, clarifying details otherwise hidden in subtle distortion.

FlareConnect™ Wireless Multi-room Audio

FlareConnect* shares audio from network and external audio input sources between compatible components. Enjoy effortless multi-room playback of LP records, CDs, network music services, and more with supported components and speaker systems. Music selection, speaker grouping, and playback management across the home are built into the Onkyo Controller app**.

* Sharing audio from external inputs is enabled with a future firmware update. External audio inputs supporting FlareConnect may differ depending on model. Please consult individual product specifications for more information. ** Download free from the App Store or Google Play.

Stream and Control with Intuitive Remote App 

The ability to control music from anywhere in your home is in your pocket: our new remote app gives quick access to your HDD library and online streaming services, and controls playback from anywhere within range of the local network.
