WiiM Amp Ultra Space Gray — Streaming Amplifier With Flagship DAC and 100W of Power

The WiiM Amp Ultra Space Gray is a compact, all-in-one streaming amplifier that drives passive loudspeakers with audiophile-grade components while removing the usual rack of separate hi-fi gear. Inside its unibody aluminum chassis sits an ESS ES9039Q2M SABRE DAC, dual TI TPA3255 Class-D amplifier stages, and TI OPA1612 op-amps, giving the unit the muscle to power bookshelf, floor-standing, in-wall, or outdoor speakers from a single box.

What Sets This Model Apart

Post-Filter Feedback (PFFB) technology actively corrects distortion after the output filter, keeping the sound consistent regardless of speaker load, while the ESS ES9039Q2M SABRE DAC supports bit-perfect playback up to 192 kHz / 24-bit. A 3.5-inch glass touchscreen lets users browse album art, switch inputs, and adjust EQ without reaching for a phone.

Technical Specifications

The amplifier section delivers 100W per channel at 8Ω and 200W per channel at 4Ω, with THD+N measured at -106 dB (0.0005%) at 5W, a signal-to-noise ratio of 121 dB, and a frequency response of 20 Hz to 20 kHz (±0.5 dB), giving listeners a clean, dynamic soundstage from a compact 2.45 kg chassis.

• Power Output: 100 W/ch @ 8 Ω, 200 W/ch @ 4 Ω — drives demanding passive speakers with headroom
• Signal-to-Noise Ratio: 121 dB — near-silent background for fine musical detail
• Wireless: Wi-Fi 6, Bluetooth 5.3 — stable hi-res streaming and modern codec support
• Streaming Services: Spotify, TIDAL, Qobuz, Amazon Music, Deezer, SoundCloud, Pandora, iHeartRadio, TuneIn — plus Roon Ready, Chromecast, Alexa Cast, and DLNA for app-based casting
• RoomFit Room Correction — auto-calibrates playback to the room using 24 EQ presets, a 10-band graphic EQ, and a 10-band parametric EQ with per-source memory

Who Should Choose This Streaming Amplifier

This streaming amplifier is built for music lovers who already own a pair of passive speakers and want to add modern streaming, TV audio, and room correction without rebuilding their system. It suits listeners who stream hi-res audio from TIDAL, Qobuz, or a local NAS, then switch to a movie through HDMI ARC. Apple AirPlay is not supported, so iPhone-centric households will rely on Chromecast or Bluetooth.
