Modernize your existing Hi-Fi system with the Yamaha WXC-70A Compact Wireless Music Streamer, a premium network audio player and preamplifier designed to bring high-resolution music streaming, TV audio, traditional components, and multi-room listening together in one compact component. Built around an audiophile-grade ESS SABRE ES9039Q2M 384 kHz / 32-bit DAC and Yamaha's proprietary DAC on Pure Ground circuit design, the WXC-70A delivers detailed, dynamic, and expressive sound while helping preserve the character of your existing amplifier and speakers.

Stream effortlessly over Wi-Fi with AirPlay 2, Google Cast™, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, Internet radio, and MusicCast. HDMI eARC/ARC makes it easy to integrate your TV with one cable, while analog, optical, USB, preamp, coaxial, subwoofer, and other connectivity options let the WXC-70A serve as the centerpiece of a flexible two-channel audio system. Choose Player Mode for use with a dedicated integrated amplifier or switch to Pre Amp Mode to take advantage of Yamaha audio processing and direct volume control.

The WXC-70A also brings Yamaha's YPAO™ room calibration with Reflected Sound Control and YPAO Volume to a compact music streamer. Using the included calibration microphone, YPAO analyzes your listening environment and adjusts playback for a more natural, balanced soundstage. A rigid aluminum enclosure helps resist unwanted vibration, while the front-panel OLED display, included remote control, MusicCast app, web setup, IR input, 12V trigger output, and Control4 compatibility make the WXC-70A equally well suited for dedicated listening rooms and professionally integrated smart-home systems.
