WiiM Amp Ultra Streaming Amplifier in Space Gray - AMP003-SPACEGRAY

WiiM AMP003-SPACEGRAY Amp Ultra Streaming Amplifier in Space Gray

One amp for music, TV, and room-tuned Hi-Fi, the WiiM Amp Ultra brings streaming, passive-speaker power, and smart control together in a Space Gray centerpiece. Built for music lovers, home theater buffs, and smart home fans, it delivers 100W per channel at 8 ohms and 200W per channel at 4 ohms with THD = 0.08% and two channels driven. That power supports bookshelf, tower, in-wall, or outdoor passive speakers across a 2-8 ohm range, while bit-perfect playback up to 192kHz/24-bit opens the door to high-resolution listening. From personal media libraries and line-level sources to favorite streaming services, it is designed to make one system the hub for everyday listening.

Inside, an ESS ES9039Q2M SABRE DAC, dual TI TPA3255 Class-D amplifiers, and six TI OPA1612 op-amps form the premium audio path behind clean, detailed playback. Post-Filter Feedback technology helps the amplifier maintain consistent performance as speaker loads change, supporting a balanced, natural presentation with clarity and depth. Built-in RoomFit acoustic measurement and correction accounts for speaker type, distance, and room acoustics, helping optimize soundstage and tonal balance for the space. A precision-machined unibody aluminum chassis combines a sleek appearance with heat-dissipating strength, while passive thermal engineering keeps operation silent.

Music access is equally broad. Wi-Fi 6, Bluetooth 5.3, and Ethernet provide flexible network options, with support for services including Spotify, Amazon Music, TIDAL, Qobuz, Deezer, Pandora, iHeartRadio, TuneIn, and SoundCloud. HDMI ARC upgrades television sound with Stereo PCM and Dolby Digital support,¹ while the glass-covered touchscreen brings playback navigation, source selection, settings, and visual feedback to the front panel. The WiiM Home App adds control from a phone or tablet, including music selection, EQ adjustment, room grouping, alarms, and firmware updates. Stereo pairing, WiiM, Google Home, and Alexa multi-room systems, plus voice control through Alexa, Google Assistant, or the included WiiM Voice Remote 2, help the Amp Ultra move naturally between focused listening, daily routines, and cinematic entertainment.

Key Features

Post Filter Feedback Technology

Traditional amplifier response can vary with the connected speaker load. PFFB monitors performance after the output filter and dynamically compensates for those changes, minimizing distortion and preserving a more accurate sound signature across compatible speakers. The refinement supports a wider soundstage and richer detail without letting the load dictate the listening experience.

Advanced Thermal Management

A copper heat pipe rapidly moves heat away from key components, while a large aluminum heatsink disperses it efficiently. Precision PID control regulates temperature in real time, and the aluminum enclosure contributes additional heat dissipation. Together, these elements support stable high-power performance without fan noise.

See Your Sound

The vivid 3.5-inch glass touchscreen places album art, VU meters, and one-tap commands front and center. Input changes, setting adjustments, and playback navigation are easy to reach, with immediate visual feedback that makes the amplifier as intuitive to operate as it is elegant to display.

Tailor Your Sound

Choose among 24 preset EQ profiles or shape playback with 10-band Graphic and 10-band Parametric EQ tools. Per-input EQ settings let different sources keep their own tuning, while adjustable subwoofer crossover and gain controls help integrate an active subwoofer through the dedicated output.

Take Full Control with the WiiM Voice Remote 2

The included remote pairs a sleek aluminum body with a rechargeable battery. Push-to-Talk voice commands, smart presets, and dedicated playback buttons put everyday listening controls in hand without requiring a phone or tablet.
