Not all great stereo systems meet all the requirements for connectivity.
I want to go on record, the Onkyo TX-Nr7100 is an awesome choice for a stereo avr. Great connectivity, a warm sound quality, and many options for your audio sound choices. But, because it's base connectivity, as it applies to Bluetooth, I do not recommend to connecting a PC to it. Due to audio and video, data separation. The Onkyo, though an excellent stereo choice, has problems playing Youtube and other types of media, with built in audio and video playback. It defaults to the miniplayer, built into the system and is impossible to get rid of in these situations. I give this product 5 stars on quality and performance, but it was not made to connect to a computer. Stll, I recommend this AVR Stereo Receiver on its aesthetic look, sound, audio and connections and quality. Very important to keep this in mind for Computer and gaming console connection to this system.

Exceptional Home Theater Receiver with HDMI 2.1, Dirac Live & THX – Incredible Value
After researching extensively and using the TX‑NR7100 firsthand with a 5.1.4 Dolby Atmos setup, I’m thoroughly impressed by its blend of features, performance, and value.
Setup & Interface
The guided setup process is smooth and intuitive—Wi‑Fi setup, firmware updates, speaker configuration and HDMI mapping all work seamlessly. The on-screen menus are clean and accessible, though some deeper options may require a bit of navigation
With six HDMI 2.1 inputs and two HDMI 2.1 outputs, this receiver supports 8K/60Hz and 4K/120Hz video formats, along with VRR, eARC, and ALLM. This makes it ideal for gaming consoles like PS5 and Xbox Series X—performance is solid with no reported signal dropouts on the primary HDMI ports.
Audio & Sound Quality
Every channel delivers up to ~100 W into 8 Ω, powering immersive content such as Dolby Atmos and DTS:X with clarity and presence. THX post-processing adds dimension and scale, especially with cinematic soundtracks. Dirac Live room correction provides musical staging, precise imaging, cleaner dialog, and deeper bass—transformative for untreated or irregular rooms.
Streaming & Multi-Room
Equipped with AirPlay 2, Chromecast, Bluetooth (including aptX), and Sonos/DTS Play-Fi integration, streaming is flexible and robust. Spotify, Tidal, Pandora, TuneIn, and more are all supported. It even functions as a Roon endpoint with no signal issues when streaming high-res audio over Ethernet.
Build & Design
The front panel features a large green display, a straightforward volume dial, and basic controls. While the remote is functional, it isn’t backlit. The control app is usable but somewhat basic, making desktop Dirac calibration a better option for fine-tuning.
Pros:
Cutting-edge HDMI 2.1 support for 8K/60Hz, 4K/120Hz, VRR & eARC
THX Certified with immersive Atmos/DTS:X and IMAX Enhanced support
Powerful and convincing Dirac Live room correction
Versatile streaming ecosystem and smart assistant compatibility
Excellent price-to-performance ratio compared to peers
Cons:
HDMI glitches possible; best addressed via firmware updates and proper setup
Remote is not backlit; app UI is basic
Not truly expandable to 11-channel systems; no independent sub outs or extra preamp channels
Verdict:
The Onkyo TX‑NR7100 strikes a remarkable balance between modern video support, superior immersive audio, and intuitive usability—all at a price point that undercuts many similarly spec’d competitors. If you want future‑proof HDMI features, strong gaming performance, Dirac‑based room tuning, and multi‑room streaming options, this AVR delivers beyond expectation. Highly recommended.
