Onkyo TX-8470 – Hi-Fi Network Stereo Receiver

Fewer channels for higher resolution sound
With a two-channel stereo receiver – instead of a larger audio video receiver (AVR) – amplifier design and components are meticulously optimized for more focused and refined audio output. Case in point: A gold-plated terminal and audio-grade capacitors provide clean sound, while our dedicated-design amplifier supports a high current drive and maximizes your loudspeaker performance, resulting in superior sound reproduction and a richer listening experience.

Built for the vinyl comeback era
Time to dust off that vintage vinyl collection…or start a new one! The Onkyo TX-8470 was designed specifically with record players in mind. Thanks to our patented discrete op amp circuitry and isolated MM/MC phono board, those delicate phono signals are kept safe from unwanted distortion for improved clarity and better overall audio performance.

Audiophile streaming built-in
Experience effortless access to your favorite high resolution music streaming platforms. Working with our partners at Roon, Tidal, Deezer and more, the Onkyo TX-8470 transforms your listening lounge into a sanctuary of hi-fi sound.

Smart home, smarter Onkyo
Our products are designed with modern smart homes in mind. Built-in third-party assistants like Apple and Google allow you to perfect your home entertainment ecosystem with best-in-class connectivity features.

Premium 2 channel DAC
Experience high resolution audio playback thanks to AKM’s premium 32bit/768kHz stereo DAC (AK4452). Capable of supporting wide range signals and at low power consumption, this DAC achieves the industry’s best low distortion characteristics.

Class G amplifier
Our high-current Class G amplifier ensures an efficient, accurate reproduction of audio signals across the entire frequency range. With our low negative feedback (NFB) design, this amp achieves greater transparency and musicality by minimizing distortion and interference for a more natural, dynamic listening experience.

Gold plated terminals
Offering superior conductivity and corrosion resistance, the TX-8470’s gold-plated speaker terminals and RCA inputs ensure optimal signal transfer with minimal signal degradation for cleaner, more stable audio connections.

Custom components
Custom transformer and low-impedance capacitors deliver unparalleled dynamism and lifelike sound reproduction, ensuring natural note transitions so nuances in attack, decay, sustain, and release are voiced with conviction.

HDMI ARC
Simplify your setup with HDMI ARC technology that uses a single cable for both audio playback and device control.

110w/ch
This robust power output provides room-filling sound with ample headroom for dynamic playback and immersive listening experiences.
