WiiM Ultra or Amp Ultra: the smarter hi-fi buy for your system

Display

WiiM Ultra wins here. It has a 3.5-inch touchscreen, which makes it the more versatile control hub for browsing inputs, checking playback, and seeing what’s going on at a glance. The Amp Ultra also includes a touchscreen, but the Ultra’s role as a preamp and streamer means that screen is central to daily use, especially if you’re switching between HDMI ARC, phono, and headphone listening. If you value front-panel interaction and system visibility, the Ultra feels more like proper hi-fi kit and less like a hidden box.

Performance

WiiM Amp Ultra wins on sheer system capability, because it includes the amplification stage. Its dual TI TPA3255 amps are rated at 100W, so it can drive passive speakers directly with real authority. That makes it a complete music system in one chassis, and the onboard ESS ES9039Q2M DAC gives it a serious digital foundation. The Ultra, by contrast, is a streamer and digital preamp: it can sound excellent, but it needs an external amplifier or active speakers to make any noise. If you already own a good integrated amp or power amp, the Ultra is all the performance you need; if you want power built in, the Amp Ultra wins decisively.

Build quality and design

This is a close one, but WiiM Amp Ultra edges it because it is the more self-contained, purpose-built product. It combines streamer, DAC, preamp, and amplifier in a single compact unit, which usually means a cleaner rack setup and fewer cables. The Ultra is also neatly made, with a premium Space Gray finish and a touchscreen that suits a modern hi-fi stack, but its real-world appeal depends on what sits behind it in your system. The Amp Ultra feels more complete and more immediately satisfying as a finished component.

Battery life

Neither product has a battery, so this category is not relevant in the usual portable sense. For a home hi-fi buyer, the practical equivalent is convenience and all-day readiness. On that basis, WiiM Amp Ultra wins because it reduces box count: one mains-powered unit, one set of speaker cables, and you’re done. The Ultra still offers excellent convenience for a fixed system, but it is inherently part of a larger chain.

Price and value for money

WiiM Ultra wins on value. At £349, it is £150 cheaper than the Amp Ultra at £499, and that saving is substantial in hi-fi terms. The Ultra also has the stronger value proposition if you already own amplification, because you are paying for the streamer, digital preamp, phono input, headphone output, HDMI ARC, and app ecosystem without duplicating hardware you already have. The Amp Ultra is still good value if you need an amp, but once you have to add a separate amplifier to the Ultra’s price, the cheaper model can easily become the smarter buy. For many systems, the Ultra leaves more budget for speakers, which often matters more to sound quality than the streamer itself.

Game library/features

WiiM Ultra wins narrowly on feature flexibility. It is compatible with Google Cast and Alexa, and it streams Spotify, Amazon Music, Tidal and more, while also adding HDMI ARC, a phono input, and a headphone output. That combination makes it unusually adaptable: it can anchor a vinyl setup, integrate with a TV, and serve late-night headphone listening. The Amp Ultra has a strong feature set too, with RoomFit EQ, HDMI ARC, Optical, RCA inputs, a touchscreen, and the Voice Remote 2, plus the ESS ES9039Q2M DAC and 100W amplification. But because the Ultra supports more system roles, it feels more universal. The Amp Ultra wins only if you specifically want the convenience of built-in speaker power and remote control.

Overall user experience

WiiM Amp Ultra wins for simplicity, while WiiM Ultra wins for flexibility. If your priority is a neat, single-box hi-fi solution for passive speakers, the Amp Ultra is the more satisfying daily experience: it powers the speakers, handles streaming, and gives you room correction via RoomFit EQ. If your priority is building a better-sounding system over time, the Ultra is the more intelligent core component. Its phono input is especially valuable for vinyl listeners, and its headphone output adds genuine late-night usability. In other words, the Amp Ultra is the easier complete product; the Ultra is the more expandable and potentially more musical foundation.

Overall summary: the WiiM Amp Ultra is the better choice if you need a streaming amplifier and want a premium all-in-one box with 100W output, RoomFit EQ, and fewer components. The WiiM Ultra is the better choice if you already have an amplifier or active speakers, because it offers more flexibility, more inputs for the money, and far better value at £349. For most serious hi-fi buyers, the Ultra is the smarter purchase; for new system builders who want simplicity, the Amp Ultra is the cleaner answer.
