WiiM Amp: Multiroom Streaming Amplifier | Compatible with AirPlay, Google Cast, Alexa | HDMI, Voice Control | Stream from Spotify, Amazon Music, Tidal & More | Space Gray

BLUF: The WiiM Amp is a great music streamer and two-channel audio amplifier. Get one, you won't regret it.[Update 7/1/24: The WiiM Amplifier (also WiiM Pro Plus and the soon to be released WiiM Ultra Preamplifier) now support WiiM's room correction. (No, the WiiM Mini does not support room correction at this time.) I do not know if the WiiM Pro (non-Plus) music streaming device supports the WiiM room correction. I only own WiiM Amplifier(s), WiiM Pro Plus and WiiM Mini music streaming devices that I purchased on Amazon.If there was still any doubt that the WiiM Amplifier and the other WiiM music streaming products sold on Amazon are the best value in audio (perhaps ever) then the WiiM room correction should convince.The WiiM room correction works with the WiiM Home app and the microphone in your smart phone. In less than a minute the WiiM Home app and supported WiiM streaming device will analyze the in-room frequency response of your speakers including a subwoofer if present in your system. The WiiM room correction creates a custom 10 band parametric equalizer response curve that you can name and save or just use the default name "Auto". The results of using the WiiM room correction with my system(s) have been impressive.LPT: You can temporarily connect a WiiM Pro Plus to any 2 channel or 2.1 channel audio system where you normally have a WiiM Mini. Then perform the WiiM room correction and save the room EQ settings. You can later write down or screenshot the room correction EQ values and manually apply the room EQ settings to the WiiM Mini at a later time. Unless you rearrange your room, change the speakers or your preferred listening position you should not need to re-run the room correction.]Tips:You can set the maximum volume level using the WiiM Home app. Use the WiiM Home app volume slider control or the WiiM Remote to control the volume. When I set the WiiM Amp's maximum volume level to ~80% the acoustic level in my home from various 4 ohm to 8 ohm speakers (ranging from ~82dB to 90dB rated efficiency) gets as loud as I want and can stand.If you are concerned that the WiiM Amp may not have sufficient power for your application then adding a powered subwoofer will make the most of the WiiM Amp's power (60 Watts per channel (WPC) into 8 ohms and 120 WPC into 4 ohms), available for the two main speakers. (I also tested the WiiM Amp's subwoofer output using the new RSL Speedwoofer 10E.)When using a turntable with the WiiM Amp you must use an external phono stage preamp as the WiiM Amp does not have a built-in phono stage. (You may want to use a phono preamp that has selectable gain or continuously variable gain to ensure an acceptable audio level when using the WiiM Amp with the turntable.)The WiiM Amp does not have a headphone output jack. I was able to successfully pair my Bose Quiet Comfort headphones with the WiiM Amp.If you experience poor Wi-Fi reception when using the WiiM Amp try moving the Wiim Amp closer to your router. (I found that rotating the WiiM Amp chassis 90 degrees also helped improve the Wi-Fi connection.) The WiiM Amp also has an Ethernet connection.Using the WiiM Amp it is possible to assemble a very satisfying and enjoyable digital streaming audio system for under $1K (WiiM Amp ($300) + Bookshelf Speakers (up to ~400/pr) + Powered Subwoofer (est. $300). You can add a CD player and/or a turntable if desired.Great:The WiiM Amp is capable of providing deep, well articulated bass. The WiiM Amp has very good dynamics, i.e. punchy even. The sound of the WiiM Amp is neutral. The WiiM Amp provides a wide soundstage.The WiiM Amp's single (mono) RCA subwoofer output connection together with the WiiM Home app's bass management functions makes pairing the WiiM Amp with a powered subwoofer super easy. The WiiM Amp automatically applies low and high pass filters when the subwoofer output is enabled.The WiiM Amp was able to effectively power every 4 to 8 ohm loudspeaker I tried quite well. I even tried driving a pair of Magnepan MG1 magneplanar loudspeakers (82dB efficiency). The WiiM Amp was able to cleanly drive each of these speakers as loud as I desired.)No audible noise or hum in either of my two WiiM Amps (I purchased a Metallic Grey and then purchased a Silver WiiM Amp.)The WiiM Amp runs cool. Even after a few hours of listening at moderately high level output the WiiM Amp chassis was barely warm to the touch.The WiiM Home app has both graphic and parametric equalizer functions. If you spend a little time learning how to master these controls you will probably be able to get the audio balance you desire.Not so great:Shipping Damage: I had purchased my first WiiM Amp, in Metallic Grey, from another online retailer. The package containing the Metallic Grey WiiM Amp was unopened and undamaged as received.I recently purchased the Silver WiiM Amp from Amazon. Although not sold as being refurbished the Silver WiiM Amp included the WiiM manufacturer's ten percent discount. One corner of the box for the Silver WiiM Amp arrived dented. The box also appeared to have been opened. However, all cables, booklet, remote and accessories were provided. The Silver WiiM Amp unit came wrapped in the factory plastic protective layer and appeared new and undamaged.Wi-Fi Performance: 2.4Ghz Wi-Fi reception is just OK, could be better. (This makes me wonder where WiiM located the internal Wi-Fi antenna in the WiiM Amp as the top and 3 sides of the WiiM Amp's case are made of an aluminum alloy.) I can't comment on 5GHz Wi-Fi performance. When I moved the WiiM Amp to another room in my home (further away from the router) the WiiM Amp would sometimes stutter or mute the audio. Rotating the WiiM Amp by 90 degrees (so that the rear of the WiiM Amp was now facing the router) seemed to improve the Wi-Fi reception.WiiM Amp Audio Performance: After auditioning the WiiM Amp with four different sets of wired speakers I found that the WiiM Amp does not provide as sharp and detailed imaging as do some other amplifiers I own. With each of the loudspeakers I tried (4 ohm, 5 ohm, 8 ohm; 2-way, 3-way, 2-way planar magnetic) the WiiM Amp's imaging lacked focus. Still, this did not take away from my enjoyment when listening to favorite selections using the WiiM Amp.Lagged WiiM Home phone app Performance: The WiiM Home phone app is sometimes lagged, i.e. when accessing the Audio Setting of the WiiM Amp. (I'm not sure if this is an app software issue or related to the limitations of the 2.4GHz Wi-Fi performance.)Lagged Remote Control Response: The WiiM Remote Control uses Bluetooth. The WiiM remote control of the WiiM Amp volume, etc. is sometimes lagged.USB Confusion: The WiiM Home App recognized the thumb drive (containing some MP3 files) that I inserted into the WiiM Amp's USB port. I was able to play the MP3 files using the WiiM Amp by selecting USB as the source. I next tried adding additional files, both MP3 and MP4 format files to the thumb drive. The WiiM Amp and/or WiiM Home app never properly updated the thumb drive file cache and never displayed an updated playlist.WiiM Amp Remote batteries: The batteries (two AAA) are not included with the WiiM Amp. (Neither of the two WiiM Amps that I've recently purchased came with the needed batteries for the remote control.)[Update 6/3/24] I purchased a WiiM Mini to solve an issue I was having with the WiiM Amplifier. The WiiM Amp is a brilliant product in almost every respect. One notable exception is Wi-Fi connectivity. In my home the WiiM Amp only has acceptable Wi-Fi connectivity when the WiiM Amp is placed close, i.e. within the same room as my wireless router. To solve this issue, I use the WiiM Mini as a Wi-Fi music streamer.I connect the WiiM Mini to the WiiM Amp via the optical cable and this gets around my WiiM Amp Wi-Fi performance issues. (The optical connection is 24 bit, 192 kbps.) I stream Spotify Premium exclusively, I can't hear any difference when using the WiiM Amp with Wi-FI (placed close to the W-Fi router) or when using the WiiM Mini and the optical output from the WiiM Mini to the optical input of the WiiM Amp.Now I can locate WiiM Amps in different rooms in my home and not have Wi-Fi connectivity issues. This works for me. Maybe this solution will work for you if you are having WiiM Amp Wi-Fi issues.

Many "influencers" have tried to take shots at this impressive bit of kit from Wiim and they are just failing miserably at it. Dollar for dollar I don't know if there is better bang for the buck in the industry. Nothing. Can you do "better" with separates? Of course, but you can't do it cheaper. Whether you are grabbing the Amp Pro as an entry into your first "real" system or putting it into duty in any number of situations, you just can't do better than this.I got the urge to get out of the house and leased a small office for (photography) studio space. I got a pair of desktop speakers for some basic audio but it's just a pain having your tunes going through the same system as your desktop. When I came across the Wiim Amp Pro it was clear it was the perfect solution for my studio space - streams from everything I care about, excuse me, room correction?? Subwoofer management? Great software to stream directly from all the things with top notch processing? Unless your immediate future involves separates, just buy it right now.I agonized over speakers on a tight budget for this little project for a while. I considered doing a powered setup or maybe going with the Wiim Amp instead of the pro. I almost pulled the trigger on the usual suspects in the $400-600 range for speakers and decided I couldn't do that. So, I scored some classics for $100, Mission 731s. For a c-buck what did I have to lose? Playlist prepped and ready and I hooked these 30-year-old speakers up to do my little future-retro setup.Wow. Just, wow.I did the room correction with the 731s hooked up, there's no sub at the moment, I was debating the sub or not forever but decided to snag one but it hasn't arrived. I probably didn't need it because these 88dB sensitivity speakers just absolutely shine with the Wiim Amp Pro. Their rating is right in its sweet spot at 25 to 75 watts.I fired up my typical torture test, the ONE track I can put on that usually tells me in moments if a setup is any good - Giorgio by Moroder by Daft Punk. You just have EVERYTHING going on with this track - spoken word, electronic, bass, classical section, non-stop funk, jazz going on, Nathan East doing the Nathan East thing on bass, full-on lead guitar runs and drums. And, on top of it all, it's incredibly layered. It's a torture test for speakers that can't keep pace with all the layers going on and amps looking to run out of steam.Never happened, track sounds fantastic with this setup even though the Wiim Amp Pro is doing all the work on the bass. Just clean, quiet power throughout, perfect imaging and separation, tight detailed mids with clean and clear highs. That, and bass that no 5" woofer hooked up to a small amp has any business putting out there. All for under $500. It's absolutely insane.I have some more playing to do with this setup but just instantly out of the box with just doing the room correction and Tidal doing its thing, it was glorious. Ran through my playlist that is just all over the place from jazz to chillhop to rock to lo-fi, smooth and nuanced through it all. Hey Nineteen kicked off the list to check the imaging and it nailed it. So What from Miles was there in all its glory, every subtlety from the track that was there including the early bass that a lot of systems turn into a boomy mess.Stop reading, just buy it. Pair it with speakers that suit your style whether they're cheap or old, as long as you aren't asking too much from these with inefficient speakers I think you'll be pleased. I have more work to do to put it through its paces but at this price, I'm confident with the rating now. Just do it.***Sub Addition Update 2025-02-26***I scored an Atlantic Technology 162 PBM that's likely 20-25 years old to pair with my setup. It's an 8" sub with 75W as my space is small, I just wanted something tight and punchy to take the bass load off the Mission 731s and the Pro Amp.I expected it to perform better with the 731s getting more power for the mids and highs but I was really astonished by just how good it all sounds.I did the room correction with the sub included and set its crossover to the max so the Pro Amp can fully control the crossover. After some experimentation I set the sub crossover to 50Hz with the gain up halfway. I corrected the room again with this crossover set and got a great corrected curve.With the Pro Amp and 731s unencumbered by producing the low bass now this setup just got that much better. The smoothness, depth, and separation coming out of this setup belies the cost for the entire package of under $600. I fired up Giorgio by Moroder for the torture test and the sound is just so incredibly clean and detailed it's really astonishing.What's really crazy is just how realistic this setup sounds. Putting on So What by Miles Davis (3995 kbps /24-bit /192kHz on Tidal) and it's like I'm sitting in a club with Miles, Trane, and the fellas all there. The opening bass line is now even more tight and punchy. Once it transitions into Miles' first solo the shimmer of Jimmy Cobb's ride cymbal just lingers in space forever. The imaging is perfect, the treble is smooth and detailed, not at all what you would expect from cheap power. This track has a ton of dynamic range and it's all there with no choking at all and perfect transient response. I thought this would be a fun and cool cheap setup; it's far far beyond that - it's definitely in audiophile territory at a crazy price.Buy it, zero hesitation. Just get yourself some efficient speakers (there's a great selection of 731s out there if you want to go my route) and you will be amazed.

I rarely do reviews but think this product justifies one. Simply and sounds quite good (extremely good for the price). The few complaining about the sound must not know how to setup and adjust an audio system. I have it running a set of B&W 607 S3s & SVS sub. Source is a Topping D10s DACa fed by USB on a Mac mini. FWIW, this is my office setup and I have Marantz w B&W 700 S3s and SVS sub in LR also so I know what a 'good' amp (and speakers) can do. A little bit of EQ correction and the sound is wonderful. Between the EQ and room correction available there is no reason you can't get this amp to sound good with any speakers that aren't total junk.I'd venture there is a huge selection of $300-500 speakers that would shine with this amp giving an affordable system with top notch sound. If possible adding a sub helps, but not a necessity and the option is always there for later.Apparently some expect a $300 Amp be equal a $3000 amp. There will be a difference of course, but that doesn't make this amp bad by any measure..I've also been very impressed with the Airplay abilities of this device. I use Apple Music mostly, but rarely use Airplay as it is of lesser quality than USB rand Apple Music lossless as a source. I was pleasantly surprised at how good Airplay sounds and works on this device.The Wiim App is very good. I spent my entire career writing SW for a living and it is refreshing how well this app works.Anyone thinking about setting up a modest priced system for streaming or other sources should seriously consider this device. Wiim makes some higher spec amps now with the Amp Pro and the Vibelink and I would have seriously considered them but the lack of Airplay and/or SW output made the regular Amp the logical choice for me.
