Onkyo TX-8470 Premium 2 Channel Stereo Receiver with Wi-Fi, Bluetooth, Phono, Hi-Res Audio and Roon Ready

• HI-FI FOR THE FAMILY: Built by and for audiophiles, the Onkyo TX-8470 Network Stereo Receiver seamlessly blends exceptional audio fidelity for music lovers with modern connectivity options for hassle-free home entertainment.
• 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.
