WiiM Amp Ultra Review 2026: Worth Buying?

The WiiM Amp Ultra is the box that made a lot of hifi shoppers cancel their bigger plans. It streams music, powers real passive speakers, handles your TV audio, and tunes itself to your room. All of that sits inside a small aluminium slab that costs around $549.

I spent weeks living with this amplifier in a normal room with normal furniture. No acoustic panels. No $10,000 speaker cables. Just a pair of bookshelf speakers, a subwoofer, a TV, and a lot of playlists.

This review covers what the Amp Ultra does brilliantly, what it fumbles, and whether it deserves your money in 2026. I will also tell you exactly who should skip it. Some people genuinely should.

In a Nutshell:

• Power is real, not marketing. The Amp Ultra delivers 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms using two Texas Instruments TPA3255 Class D chips. It drives demanding bookshelf speakers without strain and stays stable down to 2 ohms.
• The software is the star. RoomFit room correction, ten band parametric EQ, subwoofer crossover control, and automatic subwoofer time alignment are all built in. No other amplifier near this price gives you this much control.
• The 3.5 inch touchscreen is genuinely useful. You get album art, VU meters, input switching, and EQ presets at a tap. You cannot browse streaming libraries on it, though. That still needs the phone app.
• Apple users need to read the fine print. There is no AirPlay 2 support. WiiM has never explained why. Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect, Squeezelite, and Roon Ready certification are all present.
• Measured performance is excellent. Independent bench testing places it in the top tier of streaming amplifiers, with very low distortion and strong noise performance through digital inputs.
• It is not the warmest sounding amp. Traditional Class AB integrated amplifiers sound beefier in the bass. The Amp Ultra trades richness for clarity and separation.

The WiiM Amp Ultra is an all in one streaming amplifier. That single sentence hides a lot of parts. Inside the chassis you get a network streamer, an ESS ES9039Q2M DAC, a preamplifier stage with quality op amps, a Class D power amplifier, a DSP engine, and a linear power supply. WiiM squeezed all of it into a box measuring roughly 7.87 by 8.3 by 3 inches.

WiiM positions this as the flagship of its amplifier line, sitting above the WiiM Amp and the WiiM Amp Pro. The price sits near $549, though street pricing has drifted to around $529 at times.

The core idea is simple. You buy one box, add a pair of passive speakers, and you have a complete music system. Plug in your TV with HDMI ARC and you also have a two channel home theatre setup.

What separates the Ultra from cheaper WiiM models is the doubled amplifier chip count, the front panel touchscreen, the phono input for turntables, and a more refined analogue stage. The DSP features carry over to the cheaper models too, which matters when you weigh the price gap.

WiiM ships it in Space Gray and Silver. Both finishes look far more expensive than the price tag suggests. The company also includes a rechargeable voice remote in the box, which is rare at this level.

The Unboxing Experience

WiiM has clearly studied Apple packaging. The Amp Ultra arrives in a dense white box with a magnetic flap and a printed product image on top. Lifting the lid takes effort because the fit is that snug. That first resistance feels premium. It sets expectations before you see the product.

The amplifier sits in a moulded cradle under a soft cloth. Pull the fabric tab and the unit lifts out. The weight surprises almost everyone. This thing feels heavier and denser than its footprint suggests, mostly because of the internal power supply and the machined aluminium shell.

Underneath the amplifier you find a second tray. Inside sit the Voice Remote 2, a USB C charging cable for the remote, a power cable, and four banana plug connectors. The banana plugs matter because the rear panel uses banana sockets instead of traditional binding posts. If you own thick spade terminated cables, plan ahead.

There is also a thick printed manual. It covers many languages, so the English section is short and shallow. Most setup guidance lives inside the WiiM Home app instead.

Setup took me under eight minutes. I plugged in power, opened the app, and the amplifier appeared instantly. It pulled a firmware update on first boot, which took around five minutes. That gave me time to run speaker cable. The whole process feels closer to setting up a smart speaker than a piece of hifi gear.

Design and Build Quality

The Amp Ultra wears a unibody aluminium chassis. WiiM machined it as a single piece rather than screwing panels together. The result is a clean look with no visible fasteners on the top or sides. Fingerprints show a little on the Space Gray version, but a cloth fixes that.

The front panel carries the 3.5 inch glass covered touchscreen on the left and a knurled aluminium volume knob on the right. The knob has satisfying weight and a slight detent feel. Pressing it pauses playback. It is the kind of small tactile detail budget gear usually skips.

Heat management deserves a mention. Class D amplifiers run cooler than Class AB designs, but the TPA3255 still generates warmth. WiiM uses the chassis as a heatsink. After an hour of loud listening the top panel feels warm to the touch, never hot. Nothing here would burn curious fingers. The amplifier also handled hard clipping during bench testing without shutting down.

The rear panel is busy but logical. Everything is labelled clearly and spaced well enough for adult hands.

One genuine gripe: there is no physical power button. The unit sits in standby and wakes on demand. Some listeners like that. Others want a hard off switch, especially those who unplug gear during storms. WiiM made a choice here, and it will annoy a small group of buyers.

Touchscreen and Daily Control

The touchscreen is the headline feature, so let me be precise about what it does. You can switch inputs, adjust volume, choose output destination, pick EQ presets, view album art, and display VU meters. The meters look fantastic. They bounce in time with the music and make a small box feel like vintage gear.

You can also choose between several now playing layouts. One shows large cover art. Another shows track metadata with sample rate and bit depth. Audio nerds will appreciate seeing 24 bit 96 kHz confirmed on screen.

Here is the limitation. You cannot browse a streaming service library from the screen. No searching Tidal. No scrolling Spotify playlists. For that you need the WiiM Home app or a Connect service on your phone. The screen is a control and status panel, not a full interface.

Response speed is good. Taps register without lag and animations feel smooth. That was not guaranteed at this price.

In practice I used the screen less than I expected. My listening chair sits two metres away, and the screen is not readable from there. The included voice remote became my main control. It handles play, pause, volume, track skipping, presets, and voice commands. The remote is the unsung hero of this product. The touchscreen is lovely to look at and handy when you walk past, but the remote does the daily work.

Power and Sound Quality

The Amp Ultra uses two TPA3255 chips instead of the single chip found in the WiiM Amp and Amp Pro. WiiM rates it at 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms. Bench testing confirms those numbers with distortion well under 1 percent. The amplifier is stable down to 2 ohms.

It also uses Post Filter Feedback, or PFFB. In plain language, PFFB reduces the effect of your speaker impedance swings on frequency response. Speakers rarely present a flat 8 ohm load across all frequencies. PFFB keeps the amplifier behaving consistently regardless. Measured results back this up.

So how does it sound? Clean, fast, and clear. Midrange clarity is the standout. Vocals sit forward with good separation from surrounding instruments. Treble is refined rather than sharp, though poorly recorded material can sound a touch strident in the upper midrange.

Bass is where the honesty starts. The Amp Ultra goes loud and stays composed, but it does not sound as thick or as weighty as a good Class AB integrated amplifier of similar price. Compared against a Marantz Stereo 70s, the WiiM sounded leaner. The Marantz sounded richer and chunkier. The WiiM sounded cleaner and more separated.

Neither is wrong. It is a tonal preference. If you love a warm, full bodied sound, audition before you buy. If you want detail and grip, this amplifier delivers well above its price.

RoomFit Room Correction Explained

RoomFit is the reason many people choose WiiM over rivals. It is automatic room correction built into a $549 amplifier, and it works.

The process runs from the WiiM Home app. The app plays test tones through your speakers. Your phone microphone records them. The app then calculates ten points of parametric EQ to flatten the response at your listening position. The whole thing takes a few minutes.

Results in my room were clear and positive. Bass resonances smoothed out. The soundstage opened up noticeably. Room correction did more for my sound than any cable or component swap ever has.

A tip from experience. Limit the correction to around 300 Hz before you run the wizard. Room correction software fixes bass resonances well. It does very little for reverberation in the midrange and treble, and aggressive correction up high can sound unnatural. WiiM lets you set that limit, which shows real thought in the design.

The advanced settings hide behind a small gear icon that is easy to miss. Inside you can exclude the subwoofer from correction, correct left and right speakers individually or as a pair, and choose between three target curves. Harman is the default and sounds good. Multipoint measurement has also arrived in beta, which improves accuracy across a wider seating area.

You can edit each EQ point manually afterwards. Most people should leave it alone.

Connectivity and Inputs

The rear panel is generous for the size. You get HDMI ARC for TV audio, optical TOSLINK input, analogue RCA line input, a switchable phono input for moving magnet turntables, USB A for direct drive playback, and wired Ethernet.

On the output side you get banana speaker sockets, a subwoofer output, and a line level preamplifier output. That preamplifier output is a quiet superpower. If you outgrow the internal amplifier, you can add a bigger power amp and keep all the streaming and DSP features. Very few products at this price allow that upgrade path.

The phono input is a real addition rather than a checkbox. Vinyl players no longer need a separate phono stage for a basic moving magnet cartridge. Moving coil owners still need an external stage.

Wireless duties run on WiFi 6 with dual antennas and Bluetooth 5.3. Network stability was excellent in my testing, even over wireless at the far end of my home. Ethernet remains the better choice if you can run a cable.

WiiM also claims support for up to four speakers through A and B speaker switching. Treat this feature with realism. It works for background music in a second zone. It is not a way to build a surround system.

One small annoyance: there is only one subwoofer output. Dual subwoofer users will need a Y splitter and lose independent control.

Streaming Features and the WiiM Home App

Streaming support is where WiiM out feature everyone. You get Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect, Squeezelite, DLNA, and Roon Ready certification. Roon certification arrived through a firmware update and works reliably now.

Inside the WiiM Home app you get direct integration with a long list of services, internet radio, podcasts, and your own network shares. High resolution playback goes up to 24 bit 192 kHz PCM.

The app itself is dense but well organised. Settings live where you expect them. The EQ section includes graphic EQ, parametric EQ, and presets. Multiroom grouping works with a drag and a tap, and synchronisation between rooms held tight in my testing.

The missing piece is AirPlay 2. The Amp Ultra does not support it, and WiiM has declined to explain the omission. If your household runs on iPhones, iPads, and Macs, and you rely on AirPlay to send any audio from any app, this is a serious problem. Google Cast covers a lot of ground but not all of it.

There is also a tvOS app that puts now playing information on your television screen. It looks better than the front panel display, honestly. Apple TV owners get a genuinely nice bonus here.

Firmware updates arrive often. WiiM has a strong track record of adding features after launch rather than abandoning products.

Subwoofer Integration Done Right

Adding a subwoofer to a stereo system usually involves guesswork. The Amp Ultra removes most of it.

Connect a powered subwoofer to the single sub output and open the app. You can set the crossover frequency. You can then decide two separate things: whether your main speakers receive a high pass filtered signal or a full range signal, and whether the subwoofer receives a low pass filtered signal or a full range signal.

That flexibility matters. With small two way bookshelf speakers I applied a high pass filter. This freed the main driver from deep bass duty and reduced current demand on the amplifier. Clarity improved immediately and the system played louder without strain.

Then comes time alignment. The app plays test tones, listens through your phone microphone, and calculates the delay needed to align the subwoofer with your speakers. In my setup it reported a 2 millisecond offset and applied the correction automatically. I verified it manually with a slider and bass heavy tracks. The automatic result was correct.

Order of operations is important. Integrate the subwoofer first. Run RoomFit second. Doing it backwards gives worse results.

The one real limitation is filter slope. You cannot choose between different slope shapes the way expensive systems from Lyngdorf allow. For a product costing a quarter of the price, that is a fair trade.

WiiM Amp Ultra vs WiiM Amp Pro

This is the comparison most buyers actually face. The Amp Pro costs roughly $379 to $459 depending on promotions. The Amp Ultra costs around $549.

The Amp Pro delivers 60 watts per channel into 8 ohms and 120 watts into 4 ohms from a single TPA3255 chip. The Amp Ultra doubles the chip count for 100 watts and 200 watts respectively. Measured output voltage is roughly 2.4 dB higher on the Ultra at matched settings.

The Ultra adds the 3.5 inch touchscreen, the phono input, a more refined analogue stage, and 2 ohm stability. The Amp Pro has no screen and no phono stage.

Here is the honest part. Both models share the same DSP features. RoomFit, parametric EQ, subwoofer management, and time alignment all appear on the cheaper unit. And the DSP delivers more audible improvement than the amplifier upgrade does.

Listeners who compared both directly report the Ultra sounds more transparent in the midrange, cleaner in the treble, and more tonally colourful. Those differences are real but modest. You are paying a premium for refinement, not transformation.

Buy the Amp Pro if you need the features on a budget and own efficient speakers. Buy the Amp Ultra if you own harder to drive speakers, want the screen, spin vinyl, or plan to keep the unit for many years.

What the WiiM Amp Ultra Does Not Do Well

Every review should have this section. Here are the genuine weaknesses.

No AirPlay 2. This is the biggest one. Apple households lose a control method they use daily, and WiiM offers no timeline for a fix.

Bass weight is modest. Against Class AB amplifiers the Ultra sounds leaner. With larger floorstanding speakers you will likely want a subwoofer to fill in below 40 Hz. It is not a lack of volume. It is a lack of bloom.

The touchscreen cannot browse libraries. You still need your phone for real navigation, which undercuts the dream of a phone free experience.

Security update window is short. The documentation lists security fixes only through the end of 2026. For a network connected device that lives in your home for a decade, that is uncomfortable. Consider putting it on a separate network segment.

Only one subwoofer output. Dual subwoofer setups lose independent control.

No physical power switch. Minor, but real for some.

Phone microphone measurement has limits. RoomFit accuracy varies between phones, particularly on Android where microphone quality differs widely. Results remain useful, just not laboratory grade.

Banana plug only speaker terminals. Spade and bare wire users need the included adapters.

None of these are deal breakers for most buyers. They are the honest trade offs behind a very aggressive price.

Pros and Cons

Pros:

• Serious power for the size. 100 watts per channel into 8 ohms and 200 watts into 4 ohms, with stability down to 2 ohms and no thermal shutdown under abuse.
• Class leading DSP. RoomFit correction, ten band parametric EQ, subwoofer crossover control, and automatic time alignment all included at no extra cost.
• Excellent measured performance. Very low distortion and strong noise figures through digital inputs place it among the best streaming amplifiers tested.
• Huge streaming support. Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect, Squeezelite, DLNA, and Roon Ready certification.
• Premium build. Unibody aluminium chassis, glass covered touchscreen, weighted volume knob, and internal power supply rather than a wall brick.
• Real upgrade path. The preamplifier output lets you add a bigger power amplifier later and keep everything else.
• Great accessories. Rechargeable voice remote and banana plugs in the box.
• Frequent firmware updates. WiiM keeps adding features after launch.

Cons:

• No AirPlay 2 support. A genuine problem for Apple centric households.
• Leaner bass character than comparably priced Class AB integrated amplifiers.
• Touchscreen cannot browse streaming libraries. The phone app remains essential.
• Security update commitment ends in 2026 according to the supplied documentation.
• Single subwoofer output limits dual subwoofer setups.
• No hard power switch on the chassis.
• Room correction accuracy depends on your phone microphone.

Who Should Buy the WiiM Amp Ultra?

Buy this amplifier if you want one small box to replace a rack of gear. It suits apartments, offices, bedrooms, and living rooms where space and looks matter as much as sound. It suits people who want their TV, their turntable, and their streaming service running through the same speakers.

It suits curious listeners most of all. The DSP features turn this amplifier into a teaching tool. Every toggle shows you what a high pass filter does, what subwoofer delay sounds like, and how much your room is colouring the sound. That education is worth the price alone.

Skip it if you live inside the Apple ecosystem and refuse to give up AirPlay. Skip it if you crave a warm, thick, romantic sound. Skip it if you own large floorstanding speakers and refuse to add a subwoofer.

Also think carefully if you already own a WiiM Amp or Amp Pro. The upgrade is real but small. Your money would do more work on better speakers.

My verdict after weeks of listening: the WiiM Amp Ultra is the most feature complete amplifier available near $549, and the measured performance backs up the claims. It does not blow every competitor away on sound alone. It simply offers more useful capability per dollar than anything else in its class, and it does so in a package that looks and feels far more expensive.

Frequently Asked Questions

Does the WiiM Amp Ultra support AirPlay 2?

No. The Amp Ultra does not support AirPlay 2, and WiiM has not commented on why. You get Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect, Squeezelite, DLNA, Bluetooth 5.3, and Roon Ready certification instead. Apple users can still cast through supported apps or use Roon, but native AirPlay streaming from any iOS app is unavailable.

How much power does the WiiM Amp Ultra deliver?

It delivers 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms with both channels driven. Two Texas Instruments TPA3255 Class D chips handle amplification. The unit remains stable down to 2 ohm loads and uses Post Filter Feedback to keep response consistent across speaker impedance swings.

Is the WiiM Amp Ultra Roon Ready?

Yes. Roon Ready certification arrived through a firmware update after launch. Make sure your unit runs the latest firmware through the WiiM Home app, then enable the device inside Roon settings.

Can it power large floorstanding speakers?

It can drive most floorstanding speakers to satisfying volume in small and medium rooms. Deep bass authority below 40 Hz is where it shows limits. Adding a powered subwoofer and using the built in high pass filter solves that and improves clarity at the same time.

Does the WiiM Amp Ultra have a phono input?

Yes. It includes a switchable phono input for moving magnet cartridges. Moving coil cartridges still require an external phono preamplifier with appropriate gain.

Is RoomFit room correction accurate with a phone microphone?

RoomFit produces genuinely useful results, particularly for taming bass resonances. Accuracy varies with phone microphone quality, and Android devices show more variation than iPhones. Limiting correction to roughly 300 Hz gives the most natural results.

WiiM Amp Ultra or WiiM Amp Pro: which offers better value?

The Amp Pro offers better raw value because it shares the same DSP features for less money. The Amp Ultra offers better long term ownership with more power, a touchscreen, a phono input, and improved transparency. Choose based on your speakers and your budget.
