Onkyo announced the TX-8270 Network Stereo Receiver for hi-fi enthusiasts that value the benefits of two-channel listening along with modern wireless streaming capabilities. The $600 receiver boasts a massive transformer, audio-grade capacitors, and discrete non-phase-shift circuitry for high-current power.
Outputting 2 x 100 watts (8 Ohms, 20 Hz–20 kHz, 0.08%, 2 channels driven, FTC), the receiver is built around Dynamic Audio Amplification which generates high current through low impedance to control large speaker drivers with uncommon accuracy. Combining non-phase-shift circuitry for imaging clarity with discrete output transistors for low distortion, Dynamic Audio Amplification claims to deliver rhythmic and detailed sound to suit a broad range of musical preferences.
Digital signals are converted by a quality AKM 384 kHz/32-bit DAC enhanced with VLSC (Vector Linear Shaping Circuitry) filtering technology to eliminate ultra-high-frequency pulse noise. Processing is optimized for Hi-Res Audio including DSD 5.6 MHz/2.8 MHz and PCM formats up to 192 kHz/24-bit in popular file formats.
The TX-8270 features extensive connectivity that makes it quick and easy to enjoy music in any format. The receiver features Dolby Vision signal pass-through; four 4K High Dynamic Range HDMI inputs and one output with Audio Return Channel (ARC) to facilitate media player connection like Apple TV, as well as easy TV audio amplification. A rear USB input (5V/500mA) supports HDMI dongles that require power.
A moving magnet (MM) phono input; three line inputs; three digital audio inputs (two optical and one coaxial); speaker A/B outputs, and line outputs for Zone 2 (with separate DAC for distributed Net/USB/analog audio) are also included.
Wireless audio casting from smartphones, tablets and personal computers is also a highlight with 5 GHz/2.4 GHz Wi-Fi supporting AirPlay and Spotify and is ready for Chromecast built-in and DTS Play-Fi (requires a future firmware update).
Multi-room distribution is enabled by FireConnect powered by Blackfire, a wireless protocol that mirrors network and network and external analog sources (requires a future firmware update) connected to the receiver on compatible speakers, such as the upcoming Onkyo NCP-302.
Online streaming services such as TIDAL, Pandora, Deezer, and TuneIn (varies with region, and subscription fees may apply) are integrated within the receiver and Onkyo Controller app (iOS and Android), which combines receiver control, streaming service selection, and multi-room control in one simple interface.
Bluetooth wireless connectivity is featured with Music Optimizer enhancement for compressed audio, while a powered front-panel USB input supports music playback from USB flash-memory devices.
A robust metal chassis and other quality touches such as gold-plated audio inputs, binding post speaker terminals, and physical tone and balance controls round out the feature set.
