Onkyo recently announced a versatile 2-channel amplification solution with the introduction of the TX-8270 network stereo receiver. Comfortably driving loudspeakers of almost any size and impedance, the new receiver will delight listeners with rich and compelling sound.
Delivering 2x100 W (8 Ohms, 20 Hz–20 kHz, 0.08% THD+N, 2 channels driven, FTC), the receiver is built around Onkyo's Dynamic Audio Amplification which generates high current through low impedance to control large speaker drivers. The circuit combines non-phase-shift circuitry for imaging clarity with discrete output transistors for low distortion, and according to the press release, "Dynamic Audio Amplification delivers rhythmic and detailed sound to suit a broad range of musical preferences".
The amplifier features an AKM 384kHz/32bit-based 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 streams up to 192 kHz/24-bit in popular file formats.
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. Also included, are a moving magnet (MM) phono input, three line inputs, three digital audio inputs (two optical and one coaxial), two pairs of loudspeaker outputs, and line outputs for Zone 2 (with separate DAC for distributed Net/USB/analog audio). Wireless audio streaming from smartphones, tablets and personal computers is possible through Wi-Fi supporting AirPlay and Spotify and Bluetooth. The amplifier is, also, ready for Chromecast and DTS Play-Fi.
Online streaming services such as TIDAL, Pandora, Deezer, and TuneIn are integrated within the receiver and Onkyo Controller app, which combines receiver control, streaming service selection, and multi-room control in one simple interface. A powered front-panel USB input supports music playback from USB flash-memory devices.
