WiiM Amp Ultra – pure power, modern control
WiiM Amp Ultra is a high-end streaming amplifier built for music lovers, home-theater fans and smart-home setups. It delivers 100 W per channel at 8 Ω with ultra-low distortion, powered by the ESS ES9039Q2M DAC, dual TI TPA3255 modules and TI OPA1612 op-amps. The unibody aluminum chassis with a bright 3.5" glass touchscreen makes operation quick and elegant, while advanced thermal design keeps performance stable even under heavy load.
It brings next-generation connectivity with Wi-Fi 6E, Bluetooth 5.3, HDMI ARC, and wide streaming support: Chromecast, Alexa Cast, Spotify Connect, TIDAL Connect, Qobuz, DLNA, SqueezeLite and Roon Ready. The built-in RoomFit™ calibration tailors the sound to your room, and PFFB technology ensures consistent clarity regardless of the speaker load. With extensive EQ options, subwoofer control, multiroom audio and seamless app or voice operation, Amp Ultra becomes the all-in-one hub for any premium audio system.
