Onkyo Stereo Receiver Embraces Hi-Res, Wireless

The consistent trickle of new receivers in recent weeks continues, this time with a stereo model from Onkyo that offers extensive connectivity and supports high-resolution audio playback and a host of wireless networking features.

The TX-8270, rated to deliver 2 x 100 watts (0.08% THD with both channels driven into 8 ohms), features discrete output transistors to minimize distortion and high current capability to “control large speakers” as well as quality touches such as a metal chassis, gold-plated audio inputs, binding post speaker terminals, and physical tone and balance controls.

The receiver will be available later this month for $599.

Digital signal conversion is handled by an AKM 384-kHz/32-bit DAC in a receiver optimized for hi-res audio, including DSD 5.6 MHz/2.8 MHz and PCM up to 192 kHz/24-bit in popular file formats.

In addition to supporting Dolby Vision signal passthrough, the receiver provides four 4K/high dynamic range (HDR)-capable HDMI inputs and an HDMI output with Audio Return Channel (ARC) to facilitate connection to media players and TVs. A rear-panel USB input (5V/500mA) supports HDMI dongles that require power. The receiver also has a powered USB input on its front panel for music playback from USB flash-memory devices.

Connectivity options also include a moving magnet (MM) phono input, three line inputs, three digital audio inputs (two optical and one coaxial), speaker A/B outputs, and second-zone line outputs with a separate DAC for distributed audio.

The receiver supports Apple’s AirPlay, Bluetooth streaming, and wireless audio “casting” from smartphones, tablets, and computers with built-in 5 GHz/2.4 GHz Wi-Fi; Chromecast and the DTS Play-Fi wireless multiroom protocol will be supported via a future firmware update.

Wireless multiroom distribution is supported by FireConnect, which mirrors network and external analog sources connected to the receiver on compatible speakers, such as Onkyo’s new NCP-302. The capability will be enabled via a future firmware update.

The Onkyo Controller app combines receiver control, streaming service selection, and multiroom control in one “simple” interface. Onboard streaming services include Tidal, Pandora, Deezer, Spotify, and TuneIn.
