WiiM Amp Ultra 200W Streaming Amplifier with Touchscreen
The WiiM Amp Ultra is a streaming amplifier that combines network streaming, HDMI ARC home cinema integration and high-power amplification in a single compact unit. Delivering 100W per channel into 8Ω or 200W into 4Ω, it is equally suited to driving a pair of bookshelf or floor-standing speakers as it is to powering a multi-zone in-ceiling or in-wall installation. Its touchscreen control, extensive streaming support and room correction make it a strong centrepiece for a modern multi-room or home cinema system.
Why we like it
- 100W per channel at 8Ω (200W at 4Ω) from dual TI TPA3255 Class-D amplifier chips, suitable for driving up to four passive speakers
- ESS ES9039Q2M SABRE DAC and six TI OPA1612 op-amps for low-distortion, high-resolution playback up to 24-bit/192kHz
- Post Filter Feedback (PFFB) technology for stable, load-independent performance across different speaker types, including in-wall speakers
- Built-in RoomFit room correction automatically tunes output to the room and connected speakers
- HDMI ARC input with Dolby Digital decoding and a dedicated subwoofer output for integrated TV and home cinema sound
Installation notes
The Amp Ultra measures 200 x 211 x 76.2mm and is designed for shelf or cabinet placement rather than in-wall mounting. Speaker connections are via gold-plated binding posts supporting banana plugs or bare wire, with an output impedance range of 2–8Ω, making it compatible with most passive ceiling, in-wall and standmount speakers. A dedicated mono RCA subwoofer output is provided for adding low-frequency extension. Network connectivity is via Wi-Fi or Ethernet, with Bluetooth 5.3 and HDMI ARC also available as sources; note that the unit does not support AirPlay.
