Onkyo TX-8470 Hi-Fi AV Receiver

Onkyo TX-8470 — Audiophile-Grade 2-Channel Network Stereo Receiver

The Onkyo TX-8470 is a purpose-built 2-channel hi-fi network stereo receiver that trades the surround-channel count of a typical AVR for a more focused, audiophile-oriented signal path. Built around a high-current Class G amplifier rated at 110 W per channel into 8 ohms, it delivers clean, dynamic stereo playback with the modern connectivity today's listeners expect. The TX-8470 is engineered for music lovers who want a single component to anchor a two-channel system, a turntable, and a streaming library without compromise.

What Sets the TX-8470 Apart

Unlike most home-theater-flavored receivers, this stereo unit dedicates its entire amplifier design to two channels — gold-plated speaker terminals and audio-grade capacitors feed a high-current Class G output stage with low negative feedback for greater transparency. A discrete op-amp MM/MC phono board is physically isolated from the main signal path, a layout choice rarely seen at this tier and one that protects delicate phono signals from unwanted distortion. The AKM AK4452 32-bit/768 kHz stereo DAC handles high-resolution files and DSD streams, while HDMI 2.1 inputs with 8K/60 and 4K/120 passthrough keep the unit relevant for modern displays and gaming setups. A custom transformer and low-impedance capacitors round out the analog signal chain, voicing natural note transitions from attack through release.

Amplification Power and Control

Power and current delivery define how a stereo receiver drives real-world loudspeakers. The TX-8470's Class G topology switches rail voltage on demand, holding efficiency at low listening levels while reserving headroom for dynamic peaks. Dual five-way binding posts allow two pairs of speakers to be connected for A/B comparison or multi-room playback, and a dedicated subwoofer pre-out handles low-frequency extension when paired bookshelves need reinforcement.

• Power Output: 110 W per channel (8 ohms, 20 Hz–20 kHz, 0.08% THD, 2 channels driven, FTC) — ample headroom for full-range bookshelf and floorstanding speakers
• Amplifier Topology: High-current Class G with low negative feedback (NFB) — minimizes distortion for a more natural, dynamic presentation
• Dual five-way binding posts (A/B) plus a dedicated subwoofer pre-out — supports two pairs of speakers for multi-room or A/B comparison

Digital and Analog I/O for Every Source

Modern hi-fi systems juggle vinyl, streaming, and HDMI sources simultaneously. The TX-8470 accommodates all three with a generous rear-panel layout and a high-resolution DAC at the heart of its digital chain. Tone controls and balance remain available for listeners who want to fine-tune the presentation to their room and taste.

• DAC: AKM AK4452 32-bit / 768 kHz stereo DAC — handles high-resolution audio up to DSD with low distortion
• HDMI: 4 HDMI 2.1 inputs / 1 HDMI output with ARC — supports 8K/60, 4K/120, HDR10, HDR10+, HLG, plus VRR, ALLM, and QFT for gaming
• Analog & Digital Inputs: 3 RCA line inputs, 1 MM/MC phono, 2 optical, 1 coaxial, 2 USB — covers turntables, CD players, streamers, and TVs

Network Streaming and Smart Home Integration

For listeners who stream more than they spin, the TX-8470 acts as a full network endpoint. Roon Ready certification, AirPlay 2, Chromecast built-in, and Bluetooth cover most modern workflows, while the Onkyo Controller app pulls in Tidal, Spotify, Pandora, Deezer, Amazon Music HD, and TuneIn for direct access from the listening chair.

• Streaming Support: Roon Ready, AirPlay 2, Chromecast built-in, Bluetooth, Ethernet, Wi-Fi — works with Tidal, Spotify, Pandora, Deezer, Amazon Music HD, TuneIn
• Smart Home: Works with Sonos, Amazon Alexa, Apple and Google assistants — voice control and multi-room integration
• Tuner: AM/FM with 40 presets (DAB+ on select markets) — broadcast radio alongside network sources

Who Should Choose the Onkyo TX-8470

The Onkyo TX-8470 is the right choice for two-channel listeners who want a single, network-connected hub to drive a serious stereo system without surrendering HDMI convenience. Vinyl enthusiasts benefit from the discrete MM/MC phono stage with isolated op-amp circuitry, while gamers and TV viewers get HDMI 2.1 passthrough with VRR, ALLM, and Quick Frame Transport support. It suits mid-to-large listening rooms where 110 W per channel of Class G current can comfortably drive efficient bookshelf or smaller floorstanding speakers, paired with a subwoofer for full-range extension. Listeners who prefer a focused two-channel rig over a full home-theater AVR will appreciate the deliberate channel-count trade-off, which lets Onkyo concentrate engineering effort on stereo imaging, dynamics, and phono performance rather than spreading it across surround channels.
