This high-end 7.2-receiver offers multiple options for creating the inimitable movie and sound experience. The Onkyo TX-NR838 specs reveal solid build, professional physical parameters, special connects, and built-in techs for various types of audio and video. It looks very promising as a hub for the premium media system.
This model is designed in the classic Onkyo style, with simple lines and shapes and expensive touch. The front panel has a cover hiding the connection ports, while the open main controls are firm and solid. It is middle in size but rather heavy, requiring a firm surface to be placed on.
Onkyo TX-NR838 supports the majority of video formats (except AIFF), but its surround sound modes are limited by Dolby Atmos application. This receiver features considerable power consumption, while 4 Ohms of the impedance and 180W per channel allow connecting any existing speaker and derive its full power. The HDCP 2.2-protected HDMI for a second zone enables native 4K / HDR playback at the additional setup.
The unit supports several present sound fields; however, the optimal performance and equalization are available with the THX mode (the certified one). While providing many setup options, the receiver has few EQ parameters to modify. Still, the auto-calibration works steadily and tunes the system well.
This receiver provides the most of the Atmos sound. The middle line is sharply outlined, with dialogues being pure and distinct even at low volume. The highs are acute but not shrieky, at full volume might appear some digital aftertaste. The lows and bass provide solid and full impression. My Bose subs produced a powerful surge and distinct vibes without blatant booming.
This model is a connectivity genius, as it features additional HDMI ins and outs, coaxial and optical inputs, and even a phono jack. The updated Wi-Fi and Ethernet enable fast and quality streaming of any content and Bluetooth syncs with the smartphone immediately. The smartphone app is simple yet fully functional, supporting dual zones’ control.
A thoroughly developed user interface, the comprehensive, quick, and intuitive menu; controls provide quick setup and calibration. The remote is rather unassuming but simple and clear, with the handy buttons’ onset.
In Onkyo TX-NR838, nearly every feature the music and movie enthusiast might consider is implemented. Thanks to numerous certified connects, it provides the best sound and video performance of any source. The quality is top-notch, with all the newest formats supported. It also has a built-in Pure Audio tech for analog sound and a phono input. It is keen on connectivity, while setup and controls are user-friendly and intuitive.
