Digital processing is handled by an audiophile ESS Sabre ES9039Q2M DAC. The latter is supported by the proprietary D.O.P.G. technology (DAC on Pure Ground), which guarantees an exceptionally clean ground environment to preserve the nuances of analog signals. The manufacturer also integrates ASRC processing (clock reconstruction) tasked with drastically reducing jitter ([abc]jitter[/abc]) before conversion, thereby improving instrument separation. Many [abc]Hi-Res Audio[/abc] formats are supported, including [abc]DSD[/abc], [abc]Flac[/abc], [abc]Alac[/abc], [abc]Wav[/abc] and [abc]AIFF[/abc].
Yamaha WXA-70A, YPAO R.S.C. acoustic calibration and HDMI eARC
A direct legacy of the brand's Home Cinema amplifiers, the WXA-70A incorporates YPAO acoustic optimization technology (Yamaha Parametric room Acoustic Optimizer), here in an advanced version integrating reflection control (R.S.C.), a parametric equalizer (PEQ) and the YPAO Volume module. Thanks to the supplied microphone, the device analyzes the room and automatically adjusts the sound output to compensate for any shortcomings in the listening environment.
The device also bridges the video world by integrating an [abc]HDMI[/abc] [abc]eARC[/abc]/ARC input, allowing audio to be retrieved from the television with simplified volume management. A Dialogue Level function is included to enhance voice intelligibility. On the connectivity side, there is a stereo [abc]RCA[/abc] input (compatible with turntables or [abc]CD audio[/abc]), an [abc]optical[/abc] input, a [abc]USB[/abc]-A port for local file playback, and a Subwoofer output.
Yamaha WXA-70A, MusicCast multiroom and home automation integration
A true connected hub, the amplifier is built around Yamaha's MusicCast ecosystem, controllable from a dedicated mobile app for seamless multiroom management. [abc]streaming[/abc] is widely covered with support for [abc]AirPlay 2[/abc], [abc]Chromecast (intégré)[/abc], Spotify Connect, Tidal Connect, Qobuz Connect and [abc]webradios[/abc]. Audiophiles will also appreciate Roon Ready certification. [abc]Bluetooth[/abc] (SBC/AAC) is also integrated.
Finally, the WXA-70A is aimed at installers (Custom Install) by offering compatibility with the Control4 home automation platform, configuration via a web interface, a Remote ([abc]IR[/abc]) input and a 12V [abc]Trigger[/abc] output.
Availability of the Yamaha WXA-70A announced for fall 2026. Indicative price: 1,399 euros.
