Driving loudspeakers of almost any size and impedance, the versatile stereo receiver is engineered to provide rich and compelling sound. Outputting two channels of 100W (8 ohms, 20Hz–20kHz, 0.08 percent, FTC), the receiver is built around Dynamic Audio Amplification, which generates high current through low impedance to control large speaker drivers with accuracy. Combining non-phase-shift circuitry for imaging clarity with discrete output transistors for low distortion, Dynamic Audio Amplification delivers rhythmic and detailed sound to suit a broad range of musical preferences. Digital signals are converted by a quality AKM 384kHz/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 5.6MHz/2.8MHz and PCM formats up to 192kHz/24-bit in popular file formats. The TX-8270 also incorporates extensive connectivity options. 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 5GHz/2.4GHz Wi-Fi supporting AirPlay and Spotify, and is ready for Chromecast built-in and DTS Play-Fi. Multiroom distribution is enabled by FireConnect powered by Blackfire, a wireless protocol that mirrors network and network and external analog sources connected to the receiver on compatible speakers, such as the upcoming Onkyo NCP-302. 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 multiroom control in one 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. Discerning Hi-Fi enthusiasts will also appreciate the robust metal chassis, gold-plated audio inputs, binding post speaker terminals, and physical tone and balance controls. The TX-8270 will be available later this month for an MSRP of $599 (USD).
