WiiM Amp Ultra

The WiiM Amp Ultra is the amplified sibling of the WiiM Ultra streamer — a Hi-Res streaming hub and a 100W/channel (8Ω) Class-D integrated amplifier in one unibody aluminum chassis, capable of 200W/channel into 4Ω and driving up to four passive speakers directly. It's built around an ESS ES9039Q2M SABRE DAC, dual TI TPA3255 amplifier chips, and Post Filter Feedback (PFFB) technology for consistent sound across different speaker loads.

Like the Ultra, it has a 3.5" glass touchscreen, RoomFit room correction, and a 10-band EQ. Connections include line-level and optical inputs, HDMI ARC with Dolby Digital, gold-plated speaker binding posts, a subwoofer output, and USB. Wi-Fi 6 and Bluetooth 5.3 handle wireless streaming with Spotify Connect, TIDAL Connect, Amazon Music Casting, Google Cast, and Roon Ready support.
