Wiim AMP ULTRA Amplifier with Network Player (Dark Gray)

WiiM Amp Ultra Stereo Streaming Amplifier

WiiM Amp Ultra is a stereo streaming amplifier for powering passive speakers, playing high-resolution music, and improving TV sound through HDMI ARC.

Dual TI TPA3255 Class-D amplifier stages deliver 100 W per channel into 8 ohms or 200 W per channel into 4 ohms with both channels driven. Post-Filter Feedback technology helps maintain consistent performance with different speaker loads, while an ESS ES9039Q2M DAC and six TI OPA1612 op-amps handle precise signal conversion and processing.

The integrated streamer supports bit-perfect audio up to 24-bit/192 kHz together with Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, and DLNA. Wi-Fi 6E, 100 Mbps Ethernet, and two-way Bluetooth 5.3 provide flexible connections, including playback from a mobile device and transmission to compatible Bluetooth headphones or speakers.

HDMI ARC and optical inputs accept stereo PCM and Dolby Digital 5.1, while the stereo RCA input accommodates a CD player, computer, or turntable with a built-in or external phono preamp. A dedicated mono RCA output connects a powered subwoofer. The USB port can play files from storage or send up to 8-channel 24-bit/192 kHz audio to a compatible USB DAC or amplifier.

The 3.5-inch touchscreen displays album artwork and playback information while providing direct access to key controls. In the WiiM Home app, RoomFit room correction can adapt playback to the listening environment, with independent 10-band graphic and parametric EQ settings for each input and 24 preset EQ profiles.
