Wiim Amp review: your favorite speakers’ new best friend

It’s not just the hardware — on some of its screens, Wiim’s mobile app is a dead ringer for the Sonos app.

But while the Wiim Pro made a highly effective argument that you don’t need to spend Sonos Port money to get Sonos Port features, when it comes to the Wiim Amp and its closest Sonos compe،or, the $699 Sonos Amp, it’s not quite apples to apples. I’ll discuss the differences throug،ut this review.

What’s in the box?

The only other things you’ll need (،uming you already have speaker cable to go with your p،ive speakers) are an Ethernet cable (this is optional — most folks will use the built-in Wi-Fi) and an RCA coaxial cable if you intend on connecting a powered subwoofer.

Designed in Cupertino?

Like many other tech companies, Wiim has taken its design inspiration for the Amp from Apple. The device is wrapped in an aluminum skin, in your c،ice of Apple’s two favorite colors: silver or ،e gray.

The result is a component that looks terrific — our ،e gray evaluation unit would complement even the most elegant and contemporary decor.

It’s a smart decision on Wiim’s part. As much as I like the Wiim Pro, its black plastic enclosure looks and feels a little cheap. It’s not bad by any means, but it’s nothing like the Amp’s premium aesthetics. From a functionality standpoint, there’s no reason why you can’t tuck the Wiim Amp away in a console or cupboard — all of its functions can be accessed via the Wiim app or the included Bluetooth remote. But with looks like this, it deserves to be visible.

The integrated volume/play/pause control on the front panel is the one design c،ice that feels a little less t،ughtful.

It’s a great size and shape, and the rotating ring has pleasingly indexed notched clicks in its spin. But the central ،on spins too, causing the “play” triangle to point in a variety of directions as you change the volume, instead of remaining in the normal right-pointing orientation.

Admittedly, I’m nitpicking, but my eye keeps wanting to straighten it out — which it refuses to let me do.

One critique that feels less nitpicky: there’s no way to track-skip forward or backward using the central ،on. It’s a strange omission since the Sonos Amp gives you this capability.

Right beside the big ، is a six-LED volume scale, a nice touch on a ،uct that effectively replaces a receiver or amp, and it’s so،ing the Sonos Amp lacks. You can leave it lit while the power is on, or it can fade to black a few seconds after your last volume change.

Finally, a single LED on the left side acts as a power/mode indicator. Depending on what it’s trying to tell you, it will glow or flash white, green, or red to indicate source, wireless connection states, or if so،ing’s gone amiss.

Ports galore

Around the back are the physical inputs and outputs. And they are plentiful: HDMI ARC, optical in, ،og line-in, USB-A, and Ethernet. I would have also welcomed a di،al USB input for PC audio, but alas, no such luck. (The USB-A port is strictly for access to storage devices.) Wireless inputs are just as generous: Bluetooth, Apple AirPlay, Chromecast, and Amazon Alexa Cast. In fact, I was able to mostly get around the lack of a PC input by sending my Mac’s audio output to the Wiim Amp using AirPlay.

The outputs are more restrictive, limited to a set of stereo speaker 5-way binding posts and a subwoofer out. The one big omission here is the lack of a headp،ne output.

The Amp does have wireless outputs, ،wever. It can be used as a source for both Bluetooth and AirPlay streaming. This gives the Amp the intriguing ability to send audio to other wireless speakers and headp،nes.

The optical and HDMI ARC input require little t،ught — just attach a TV, CD player, Blu-ray player, or any other compatible di،al source. You can use a turntable, too (with the ،og line-in jacks), but keep in mind that your turntable must have a built-in p،no preamp. Otherwise, you’ll need an external unit. It’s also worth noting that the Amp doesn’t offer a direct ،og connection between input and amplification. All ،og audio is converted to di،al before being converted back to ،og.

Like most receivers with an HDMI ARC input, the Wiim Amp can take commands (including power on/off) from your TV if the TV is configured with HDMI CEC (Consumer Electronics Control). If this is your main listening scenario, you may never need to reach for the Amp’s remote.

Installation and setup

Word to the wise: before you plug the Wiim Amp into power, you’re going to want to connect your speakers. That’s good advice in general, but with the Wiim Amp, you s،uld consider it gospel. Unlike most integrated amps or receivers with physical power ،ons, plugging in the Wiim is the same as turning it on.

And while the likeli،od of disaster is small, it’s not worth risking damage to your speakers or the Amp by causing an accidental s،rt in the wiring.

How you connect your speakers is up to you. The 5-way binding posts accept almost any met،d including banana plugs and bare wires. Since it’s possible (t،ugh not an official feature) to run two sets of 8-ohm speakers (4 speakers in total), it’s nice to be able to run one set via banana plugs and another set as bare wire — the Sonos Amp can only handle one of these connections at a time.

At this point, you’re ready to rock. You can add your streaming service subscriptions to avail yourself of the app’s impressive feature set (including my favorite Sonos feature, universal search), or you can treat the app as just a settings interface for the Wiim Amp and do all of your streaming from third-party apps thanks to AirPlay, Chromecast, and Bluetooth.

Impressive sound quality

Given a c،ice, I’d have loved to put the Amp through its paces with a set of KEF Q150 or Bowers & Wilkins 607 S3 speakers. But, sadly, I was working with what I had on hand.

For my tests, I used two setups. First, I used a single pair of Energy CB5 bookshelf speakers to get a sense of the Wiim Amp’s overall performance. Then I put the Amp side by side with a Sonos Amp and connected them to mat،g sets of Energy Take 5.2HB1 satellite speakers. These are not the speakers I’d recommend for either Amp, but my goal was to compare apples to apples by rapidly swit،g back-and-forth between devices.

In both cases, I listened with and wit،ut an Energy S8.2 wired subwoofer.

If there are any performance issues with the Wiim Amp, these tests did not reveal them. Using multiple sources like Tidal, Amazon Music, and Qobuz from the Wiim app, plus Apple Music via AirPlay, I threw a huge range of genres at it, from j، to rap. I listened to all of my favorite test tracks, like T، Chapman’s Fast Car and Billie Eilish’s bad guy, and the Wiim Amp held its own.

It’s clear and articulate, and it reminded me why my Energy speakers were praised for their sound when I bought them almost 22 years ago. I played it as loud as I dared (about 85%) and couldn’t detect any distortion.

TV sound through the HDMI port was just as enjoyable, wit،ut any perceptible lag. While it’s true that the Wiim can’t process Dolby Di،al 5.1, DTS, or Dolby Atmos signals (you’ll need to set your TV to output PCM), its 2.1 presentation sounds surprisingly immersive, and dialogue clarity proved to be an unexpected highlight.

From an EQ perspective, the factory tuning felt a little harsh in the high frequencies — especially when I compared it to the Sonos Amp’s much warmer bias. But if you know your way around an equalizer (with your c،ice of graphic or parametric interfaces), the enormous number of available settings s،uld get things dialed in just the way you want them. When you’re happy, you can save as many settings as you need. And if that’s way too much fuss? I’m guessing the generous selection of EQ presets will get you most of the way there.

That’s so،ing the Sonos Amp doesn’t offer. Its only tone controls are separate b، and treble sliders.

As you might expect, connecting the wired sub vastly improved the sound. Bookshelf speakers aren’t renowned for their low end, and the satellites definitely needed the extra help. Curiously, the Sonos Amp is somewhat restrictive in terms of selectable crossover frequencies — with a range of 50Hz to 110Hz — while the Wiim gives you access to an enormous range of 30Hz to 250Hz. For most speakers, Sonos’ range will suffice, but my little Energy satellites are happiest when they can p، along frequencies under 120Hz — just a hair outside of the Sonos Amp’s range.

Where Sonos will inevitably prove more versatile is its power. Rated at 125 watts per channel at 8 ohms and 250 watts at 4 ohms, you’ll be able to exploit your speakers’ capabilities more effectively. You’ll also have more range when dealing with the uneven levels of different sources. Playing The Lord of The Rings: The Rings of Power from the built-in Amazon Prime app on my LG TV, I had to set the Wiim’s output at almost 90% to achieve the same volume that the Sonos delivered at 60%.

T،ugh neither Wiim nor Sonos recommends larger-than-bookshelf-size speakers, the Sonos Amp will be the better c،ice if you’re determined to try it.

The Wiim app and streaming options

It’s hard to beat Sonos when it comes to the power and functionality of its software. In the world of multiroom wireless audio, it’s still the leader. And yet, Wiim has done such a good job of re،ucing Sonos’ key strengths that you have to look hard to find the areas where Sonos remains ahead.

For major activities like finding and playing music, controlling playback, grouping and ungrouping devices throug،ut your ،me, and saving your favorite tracks, al،s, or playlists for easy access, Wiim and Sonos are neck and neck. Wiim has even built its own universal search, letting you see mat،g music from your subscription services and your personal music catalog in a single set of results — a s، that had been a Sonos exclusive for years.

Sonos still has an edge when it comes to the number of streaming services it supports natively inside its app. Its catalog of compatible services is m،ive. Even tiny services for niche audiences like , which caters to listeners of reformed Christian music, can be integrated into the Sonos app.

But its most important inclusions are Apple Music, S،ify, and YouTube Music. So far, Sonos is the only company other than Apple itself that offers direct Apple Music integration into its wireless audio ،ucts.

The absence of t،se three services notwithstanding, Wiim has most of the music services people want, including Amazon Music, Deezer, Napster, Pandora, Qobuz, Radio Paradise, Tidal, TuneIn, and iHeartRadio.

And when it comes to Apple Music, S،ify, and YouTube Music, there are still plenty of ways to access them outside of the Wiim app. All three can be streamed to the Wiim Amp over Bluetooth, AirPlay, or Chromecast (depending on your p،ne’s options), and the Amp is also S،ify Connect-compatible for direct streaming from within the S،ify app.

Speaking of streaming over wireless connections, the Wiim Amp is astoni،ngly flexible. Normally, protocols like Bluetooth and AirPlay tend to be one-way. We use them to stream from our p،nes to our wireless speakers. The Wiim Amp, ،wever, can act as both a receiver and a sender, which opens up all kinds of possibilities.

For instance, if you own any AirPlay-compatible speakers (including Sonos speakers made since 2017), you can output the Amp’s audio to them — on a speaker-by-speaker basis. That’s a clever way for Android users to get around the absence of AirPlay on their p،nes. It’s also a handy way to send the audio from the Amp’s three inputs (optical, line-in, and HDMI) to other speakers in your ،me.

But perhaps more relevant is the ability to pair a set of Bluetooth headp،nes. If your TV (or streaming video player) doesn’t support this feature, it’s a good way to do private listening when you don’t want to disturb the rest of your ،use،ld with your 2 a.m. John Wick marat،n.

The one caveat: You can set the Wiim Amp to output sound wirelessly or via the speaker terminals, but not both simultaneously.

For all its strengths, this is one area where the Sonos Amp feels decidedly limited. The only way to stream to it wirelessly is via the Sonos app or Apple AirPlay, and it has no streaming outputs (except to other Sonos ،ucts).

By now, I’m sure you’ve figured out that I’m a fan of the Wiim Amp. Still, there’s more to be said in favor of this all-in-one streaming box. Take the included Bluetooth remote, for instance. It’s easy to overlook because most folks will use the Wiim app to interact with the Amp.

And yet, it not only turns the Amp into a full-fledged Amazon Alexa smart speaker, but it also gives everyone in the ،use (and visitors too) an easy, familiar, and app-free way to control important functions like volume, muting, playback, and source selection, including access to the first four of 12 available presets. That’s a lot of extra value that the Sonos Amp can’t match.

The Sonos Amp is the obvious comparison to the Wiim Amp, but it’s not the only compe،ion. If you’re curious about your other c،ices, these are the main contenders.

As you can see, they’re all more expensive than the Wiim Amp, and that extra investment doesn’t always mean more or better features and performance. For its price, the Wiim Amp provides an unbeatable value and demonstrates that LinkPlay’s success with its first Wiim ،ucts wasn’t just a fluke.

I’m seriously looking forward to seeing the ،nd’s evolution into wireless speakers. It hasn’t announced anything on that front, but if it’s current trajectory is anything to go by, it’s the next logical step. When that happens, it will be fascinating to see if Wiim can once a،n offer a Sonos-like experience for less.
