WiiM Amp Ultra with Voice Remote 2 Review | 100W Streaming Amplifier

Power, Purity, and Smart Connectivity — All in One Compact Box

The WiiM Amp Ultra is the new benchmark in modern streaming amplifiers. It’s small, sleek, and yet astonishingly powerful — delivering 100 watts of clean audio per channel, a reference-grade ESS ES9039Q2M DAC, and dual Texas Instruments TPA3255 amps for remarkable clarity and headroom.

Add to that HDMI ARC, optical, RCA, and subwoofer outputs, plus built-in RoomFit EQ, and you get an amplifier that doesn’t just play — it adapts to your space, your speakers, and your sound preferences.

This is the kind of device that turns any traditional speaker setup into a future-ready, high-resolution smart audio system.

Design & Build Quality: Minimalist, Modern, and Solidly Engineered

Right out of the box, the WiiM Amp Ultra feels premium — compact, dense, and crafted with attention to both aesthetics and acoustics.
Its Space Gray aluminum chassis exudes modern elegance, while the rounded edges and touchscreen interface make it as intuitive as it is beautiful.

The front panel features a responsive glass touchscreen for quick volume and playback control, while the included Voice Remote 2 gives you instant access to your music, streaming services, and smart-home commands.

At just a few inches wide and tall, it fits anywhere — from desktop setups to full living-room systems — yet feels like a piece of high-end hi-fi gear designed to impress both audiophiles and design enthusiasts alike.

Amplification: Dual TI TPA3255 Power Amps Delivering True 100W RMS

Under its refined exterior lies serious power. The dual Texas Instruments TPA3255 Class D amplifiers are tuned for 100W RMS per channel (8 ohms) and 160W per channel (4 ohms) — giving the WiiM Amp Ultra the muscle to drive everything from compact bookshelf speakers to large floorstanders.

The sonic signature is clean, dynamic, and effortlessly controlled. Even at higher volumes, distortion remains inaudible, and the bass retains tight precision instead of booming or muddying the midrange.

The amp delivers incredible transparency — every note and instrument is separated clearly, making it ideal for both critical listening and everyday streaming.

DAC & Audio Quality: ESS ES9039Q2M – Studio-Grade Precision

At the heart of the WiiM Amp Ultra is the ESS ES9039Q2M DAC, one of the most respected chips in the high-end audio industry.

This DAC ensures ultra-low noise and distortion while supporting up to 32-bit/384kHz PCM and native DSD playback.
The result is breathtaking clarity: crystal highs, lush mids, and deep, textured lows.

Whether you’re streaming lossless audio from TIDAL, Qobuz, or playing locally stored hi-res files, you’ll hear detail and spatial depth that simply outclasses most all-in-one streamers in this price range.

RoomFit EQ: Personalized Acoustics for Every Room

One of the standout features of the WiiM Amp Ultra is RoomFit EQ — a smart room-correction system that analyzes your acoustic environment and automatically adjusts frequency response for optimal sound balance.

Using the built-in microphone or your smartphone, RoomFit measures reflections, bass peaks, and resonance points to deliver balanced audio tailored to your specific space.

The result?
No boomy bass, no hollow mids, no overly bright highs — just clean, natural sound fine-tuned for your exact room layout and speaker positioning.

The included Voice Remote 2 takes convenience further. It features a built-in microphone for voice commands, shortcut buttons for quick access to favorite services, and responsive navigation for menus and playlists.

Combined with the WiiM Home app, you can control every aspect of the amplifier — from DSP filters to firmware updates — without leaving your chair.

Performance: Crisp, Powerful, and Engaging

When paired with quality speakers, the WiiM Amp Ultra performs far above its size class.

• High frequencies are silky smooth and finely detailed, revealing cymbal shimmer and vocal clarity.
