Onkyo TX-8470 Connected Stereo Amplifier

The Onkyo TX-8470 is a hi-fi stereo amplifier designed to deliver remarkable sound quality and modern connectivity. It combines precise sound reproduction with easy integration into a connected environment.

The TX-8470’s amplification operates in class G, combining the musicality of class AB with increased energy efficiency. Onkyo’s meticulous internal design uses carefully selected components, such as an oversized power supply and pure copper circuits to reduce noise and interference, with gold-plated terminals ensuring optimal signal transmission.

Amplification and Audio Performance

The TX-8470 features an amplification stage delivering 2 x 120 W at 8 ohms, with peaks at 2 x 140 W at 4 ohms. This power, coupled with a very low distortion rate, allows you to fully exploit the potential of various speakers, whether bookshelf or floor-standing.

The AKM 32-bit / 768 kHz DAC offers high precision in digital signal processing. The extended dynamic range and low harmonic distortion (THD+N of 0.08%) result in detailed and natural sound reproduction, from crystal-clear highs to deep bass.

Special attention is given to the MM/MC phono preamplifier. Its dedicated circuit and separate linear power supply reduce background noise and preserve the harmonic richness of vinyl records, offering clarity and dynamics close to the best digital sources.

Comprehensive Connectivity

The TX-8470 excels in connectivity:

• 4 HDMI 2.1 inputs (8K/60Hz, 4K/120Hz, ALLM, VRR, QFT) including 1 ARC output
• 2 optical and 1 coaxial inputs for digital sources
• 3 RCA line inputs, 1 phono input, 1 pre-out, and 1 subwoofer output
• FM/DAB+ radio tuner with 40 presets
• USB ports for playing audio files up to 24-bit / 192 kHz
• Ethernet and dual-band Wi-Fi network connectivity
• Bluetooth, AirPlay 2, Chromecast built-in for wireless streaming
• Compatibility with voice assistants and home automation systems
• Zone B speaker output to sound a second room

The TX-8470 efficiently handles all sources, whether vinyl records, 4K movies, or Hi-Res music streaming. Its HDMI 2.1 compatibility supports the latest video formats like 8K HDR and 4K 120 Hz.

High-Definition Audio Streaming

Thanks to its gigabit Ethernet and Wi-Fi controllers, the TX-8470 easily accesses a wide range of digital music. It is Roon Ready certified and supports HD streaming services such as Spotify Connect, Tidal, Qobuz, Deezer, and Amazon Music. Web radios and podcasts are available via TuneIn.

AirPlay 2, Chromecast, and DTS Play-Fi protocols are integrated for wireless streaming from various devices. Bluetooth is also present with SBC and AAC codecs.

The TX-8470 supports high-resolution audio files up to 24-bit / 192 kHz in FLAC, WAV, AIFF, and ALAC formats, as well as DSD 5.6 MHz, played from a USB device, DLNA server, or NAS. It also handles multiroom, integrating into systems like Sonos, Denon HEOS, or Yamaha MusicCast.

Advanced Gaming Features

Gamers also benefit from the TX-8470’s gaming features:

• Automatic Low Latency Mode (ALLM) for optimal responsiveness
• Variable Refresh Rate (VRR) for increased smoothness
• Quick Frame Transport (QFT) to reduce latency
• Optimizations for gaming consoles (PS5, Xbox Series X)

These technologies enhance the gaming experience by eliminating lag and stutter, perfectly synchronizing sound and image.

Easy Calibration and Control

The TX-8470 offers calibration tools, including the AccuEQ function that measures room and speaker response, automatically adjusting settings for optimized playback. Fine adjustments are also possible.

The amplifier is intuitively controlled via its user-friendly interface, the provided remote control, or the Onkyo Controller app for smartphones, allowing access to all functions and sources, including streaming services. It can also be voice-controlled via Google Assistant or Apple’s Siri.
