Product Overview
The Onkyo TX-NR595 is a 7.2-channel network receiver that delivers 80 watts per channel (into 8 ohms, 20 Hz–20 kHz, 0.08% THD, with 2 channels driven). This power delivery is backed by Onkyo’s proprietary Dynamic Audio Amplification (DAA) system. DAA utilizes a custom-designed, High-Current Low-Noise Power Transformer, customized capacitors, and a discrete amp output stage. This design philosophy focuses on maintaining high current delivery to handle rapid changes in the audio signal, ensuring dynamic, punchy sound reproduction even when driving demanding, low-impedance 4-ohm speakers.
From a video standpoint, the TX-NR595 is fully equipped for 4K Ultra HD setups. It features six HDMI inputs and two HDMI outputs, all of which support 4K/60p, High Dynamic Range (including HDR10, HLG, and Dolby Vision), BT.2020 color space, and HDCP 2.3 copy protection. This makes it a highly capable hub for Ultra HD Blu-ray players, streaming devices, and gaming consoles.
Where the TX-NR595 truly shines is its integration of smart home and streaming technologies. As a Smart AVR, it acts as a digital streaming bridge. It comes with built-in access to popular streaming services such as Amazon Music, Spotify, Pandora, TIDAL, Deezer, and TuneIn. It also supports multi-room wireless audio distribution protocols, including Apple AirPlay 2, Chromecast built-in, and DTS Play-Fi.
Furthermore, its unique integration with the Sonos ecosystem allows it to merge seamlessly with existing Sonos setups when paired with a Sonos Connect or Port. This means you can wake the receiver, change its inputs, and control its volume directly from the intuitive Sonos smartphone app. For vinyl enthusiasts, Onkyo has also included a dedicated Phono (MM) input with a built-in equalizer, allowing direct connection to a turntable.

Pros
The Onkyo TX-NR595 is packed with features that cater to both home theater purists and casual streaming enthusiasts. After examining its hardware design, user reports, and feature set, several key advantages become clear:
Immersive Surround Sound Formats
The TX-NR595 is fully compatible with both Dolby Atmos and DTS:X. It allows you to build a 5.2.2-channel configuration, utilizing two overhead height speakers (or up-firing Atmos-enabled speakers) alongside your standard surround speakers. For users who do not have dedicated height speakers, the receiver features Dolby Atmos Height Virtualizer and DTS Virtual:X. These digital processing features mimic the three-dimensional overhead sensation using your standard listener-level speaker layout. This brings movies and modern games to life with impressive directional accuracy.
Seamless Sonos System Integration
For homes already utilizing Sonos multi-room audio, this receiver is a dream come true. Once you hook up a Sonos Connect or Sonos Port to the TX-NR595, the receiver receives a “Works with Sonos” certification. This ties the AVR directly to your Sonos ecosystem. You do not need to walk over to the receiver or find its remote to turn it on or switch inputs; simply selecting a song in the Sonos app will wake the TX-NR595, switch it to the correct input, and adjust the volume.
Excellent Wireless & Multi-Room Audio Options
In addition to Sonos, the TX-NR595 is equipped with comprehensive smart capabilities. Support for Apple AirPlay 2 allows iOS users to stream high-fidelity audio flawlessly from their Apple devices. Chromecast built-in allows Android users and Google Home owners to cast audio directly from compatible apps, and integrated DTS Play-Fi offers another robust avenue for multi-room home synchronization. Dual-band Wi-Fi (5 GHz / 2.4 GHz) ensures a stable, drop-free connection even when streaming high-resolution audio files.
Superior Audio Hardware & Power Delivery
Onkyo has loaded this unit with high-quality internal audio components. The heart of its digital-to-analog conversion is the premium AKM AK4458 384 kHz/32-bit DAC, which processes high-resolution audio files with incredible clarity and minimal distortion. Combined with Dynamic Audio Amplification (DAA), the receiver delivers tight bass control, realistic mid-tones, and crisp high frequencies. It handles instantaneous dynamics effortlessly, which translates to a more exciting, cinematic performance when explosions or sudden music swells occur in a film.
Dedicated Phono Input for Vinyl Enthusiasts
Many modern mid-range home theater receivers omit a phono input to save on cost, forcing vinyl collectors to purchase external phono preamps. Onkyo wisely included a dedicated Phono (MM) input on the TX-NR595. This makes it incredibly easy to connect a turntable directly to your home theater and enjoy your vinyl record collection with the warm, analog amplification of Onkyo’s discrete output stages.
AccuEQ Calibration and AccuReflex Technology
Setting up surround speakers can be intimidating, but the included AccuEQ automatic calibration mic takes the guesswork out of the process. By plugging in the microphone and running the wizard, the receiver measures speaker distances, levels, and crossover frequencies while applying equalization to compensate for your room’s acoustics. Additionally, the AccuReflex feature phase-aligns the sound coming from up-firing Atmos speakers with the direct sound from your floor speakers, eliminating muddy reflections and sharpening the overhead 3D soundstage.

Cons
While the Onkyo TX-NR595 is a remarkably versatile and high-performing receiver, it is not without a few drawbacks. To provide a balanced perspective, here are the limitations you should consider before making a purchase:
Limited to 4K/60Hz (No HDMI 2.1 or 8K Support)
Because the TX-NR595 is a 2019 model, it was manufactured prior to the widespread adoption of the HDMI 2.1 standard. While it passes 4K Ultra HD video flawlessly at 60Hz, it does not support 4K/120Hz or 8K pass-through. For modern console gamers owning a PlayStation 5 or Xbox Series X, this means you will not be able to take advantage of advanced features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), or high-frame-rate 120Hz gaming directly through the receiver’s HDMI inputs. You would have to connect your console directly to a compatible TV and route the audio back to the receiver via HDMI ARC.
Utilitarian and Dated User Interface
The on-screen display (OSD) and setup menu of the TX-NR595 get the job done, but they look distinctly dated. The user interface uses simple, low-resolution block graphics that feel like they belong to a previous decade. While it is functional, navigating deep settings or setting up advanced networking parameters can feel somewhat clunky compared to the highly polished, modern graphical user interfaces found on competitor brands like Denon or Marantz.
Zone 2 Source Limitations
The TX-NR595 has a powered Zone 2 output, allowing you to run a second set of stereo speakers in another room (like a kitchen or patio) while maintaining a 5.2-channel system in your main room. However, the receiver has limitations on what audio sources can be shared to Zone 2. Specifically, certain digital inputs (connected via optical or coaxial cables) or specific wireless network stream configurations (like DTS Play-Fi) may not play through the Zone 2 output without complex workarounds, often requiring you to use analog RCA inputs for multi-zone playback.
“Works with Sonos” Requires Additional Purchases
While the Sonos compatibility is a fantastic feature, it is important to clarify that the receiver does not have a Sonos player built-in. To use this feature, you must own or purchase a separate hardware unit—either the legacy Sonos Connect or the modern Sonos Port—which adds to the overall cost of your system if you do not already own one.

Customer Reviews Analysis
With 191 customer reviews on Amazon, the Onkyo TX-NR595 has developed a strong reputation among home theater enthusiasts and casual users alike. Analyzing these reviews reveals a clear picture of how this AV receiver performs in everyday households.
The vast majority of positive reviews highlight the superb audio quality and power delivery. Users frequently note that the 80 watts per channel rating feels incredibly conservative. The receiver easily drives large floor-standing tower speakers and delivers crisp, distortion-free audio even at high volumes. Film lovers rave about the Dolby Atmos performance, reporting that the height channel virtualization does a surprisingly convincing job of placing overhead sound cues, such as helicopters or rain, above the listener.
Another major point of praise is the versatility of wireless inputs. Families enjoy how easily they can switch from watching a 4K movie to casting a playlist from their smartphones via Bluetooth or AirPlay 2. The setup of regular speakers is also described as highly straightforward, with the AccuEQ microphone calibration system being lauded for correcting problematic room echoes and delivering a well-balanced soundstage.
However, customer feedback also highlights some common pain points. A recurring issue raised by users is the learning curve of the multi-zone audio setup. Several reviewers expressed frustration when trying to get network streaming features or certain digital inputs to play in Zone 2, noting that the included physical instruction manual is quite basic. To resolve these configuration issues, many users had to search online to download the comprehensive, full-length digital manual from Onkyo’s website.
Other minor gripes include the requirement of having your television turned on in order to navigate some of the deep network configuration menus. Some buyers also reported that the receiver can run quite warm when pushed hard for several hours, suggesting that it needs plenty of ventilation inside an entertainment cabinet to prevent thermal shut-offs.
Overall, the general sentiment is incredibly positive. Users agree that for a price tag of $699, the Onkyo TX-NR595 offers an outstanding balance of performance, modern features, and high-fidelity sound, making it a highly competitive choice in its class.

Who Should Buy This Product?
The Onkyo TX-NR595 is a highly adaptable receiver, but it is best suited for specific types of users:
- Sonos Ecosystem Owners: If you already have Sonos speakers throughout your house and want to bring a full, traditional 7.2 home theater setup into the same ecosystem without sacrificing ease of use, this receiver is tailor-made for you.
- Movie Lovers wanting Dolby Atmos: Anyone looking to experience high-quality object-based surround sound (Dolby Atmos or DTS:X) without necessarily having to cut holes in their ceiling will benefit immensely from the Height Virtualization features.
- Vinyl and Streaming Hybrid Users: If you enjoy the warm sound of classic vinyl but also rely on modern streaming services like Spotify, Amazon Music, or Tidal, this unit combines both worlds flawlessly with its Phono input and built-in network features.
- Homeowners setting up dual zones: Those who want a high-powered 5.2 surround sound system in their main living room, while routing a secondary set of stereo speakers to an adjacent dining room or patio.
Who should pass? Hardcore next-generation console gamers who prioritize playing games at 4K resolution with a 120Hz refresh rate should look for a newer receiver that supports HDMI 2.1. Additionally, if you are looking for a simple, plug-and-play solution without dealing with speaker wires, a high-end soundbar might be more appropriate than a full AVR setup.
