I really liked the idea of the Chromecast Audio but was always frustrated with its lack of support for Hi-Res Amazon Music playback and what I felt was relatively poor sound quality via the Toslink output. Looking to replace it, I struggled to find something suitable. I wanted a device with digital audio output(s) for use with my external DAC, Amazon Music HD/UHD compatibility at full resolution, and the ability to play local files stored on my NAS. Amazon's Echo Link came close but lacked high-res audio support over its Toslink output making it a no-go. The Bluesound node had everything I wanted but came with a price tag that made me pause to scour for any other possible alternatives. I then remembered a device that I had seen advertised by a value oriented Hi-Fi Youtuber: The Wiim Mini.

After taking a look at the Wiim, I found out that it checked most of my boxes and though it definitely worth a listen given the affordable cost. I also noticed that it ran on 5V DC power, thus allowing me to power it with an extra iFi iPower 2 power supply I had laying around. I also had a spare Pangea Premier SE Toslink cable to connect it to my DAC (a Denafrips Ares II). I was immediately struck by the audio quality of the combination on my system.

I find the Wiim Home app reasonably easy to use, the settings fairly intuitive, and the pace of updates makes quite clear that Wiim is listening to and addressing its customers' issues. I've encountered a couple of bugs with pausing tracks, but those have largely been addressed. I really like that after the app updates, I'm greeted with a brief description of changes / fixes applied. That along with the pace of updates inspires a pretty high degree of confidence in Wiim's support. I also love the ability to manually connect to an online stream and save it as a preset. I use this feature to listen to the BBC World Service's higher bitrate AAC stream. Playback of high-res files from my NAS is also a snap.

All in all, I really love the Wiim Mini's awesome functionality, great sound quality, via Toslink, and the idea that even with the upgraded power supply and Toslink cable, it still came in under half the price of the Bluesound Node. I rarely take the time to write a review, but this thing is absolutely worth it to do so along with its great price. I wouldn't hesitate to recommend it to anyone looking for a great sounding & inexpensive streamer.

Pros:
* Sounds wonderful via the Toslink output and an external DAC
* Full-size Toslink fully supports 24 bit / 192 kHz output.
* Most affordable streamer to support Amazon Music HD/UHD.
* Utilizes 5V DC power making it compatible with iFi iPower & linear power supplies for a great upgrade
* Supports a wealth of playback & streaming service options
* Looks to be adding support for casting Amazon HD/UHD audio from the Amazon Music app (yea!)

Cons:
* A few minor bugs in the Wiim Home app (pause/play mainly).
* Have found myself looking for and not finding a simple stop playback (square) option.

I was contemplating buying the Belkin equivalent of this device for airplay. I had seen that the reviews for it were not that great, it had constant disconnection issues. I read one review that recommended buying the WiiM instead. I was so glad I listened to that person. This device is worth every cent. It is incredibly easy to set up using the app, took me less than 7 minutes from opening the box to playing music on it. Although it did have to update too. This is a solid product if you are looking to add airplay to your stero. It also has alexa integration as well. Highly recommend buying this over any other airplay device.

Great streamer in a tiny package. Super easy Wi-Fi setup though my iPhone and was streaming to it via airplay in a couple minutes. Connected via included optical cable to my older Denon and the sound quality is very good. Not quite the quality of my blusound node, but at a fraction of the price it definitely holds its own. Great, reasonably priced solution for streaming to vintage stereo equipment. Bluetooth works well, but Wi-Fi streaming is definitely better. Decent app though I just stream from my phone to it via AirPlay.
Only thing I wish I could lock the volume out to let my stereo control the volume completely. Minor issue, and again at this price I highly recommend it.

My daughter and son in law have a sound sticks 2 for their tv but no way to stream music from their phones for the 4 y/o daughter. She is always asking for music. The Wiim mini hooked up easily .

I assumed (wrongly) I could input the optical cable from the tv to the Wiim. It turns out the optical port on the mini is an output only. I used their existing inexpensive DAC output which was going to the sound sticks. I routed that to the aux input on the mini with a mini plug - rca cable I had. Then using the app audio source choose to stream music to the speakers or use the aux input to play the Tv sound. Much cheaper than a receiver and takes up no space. Have to be careful with sound volume when switching sources.

Thanks Wiim!

Wonderful device. Connects to the Phono input on my twelve-year old Yamaha receiver which drives Klipsch speakers. It is so convenient to stream my music from iPad or iPhone without having to locate a specific CD and doing it that way.

Connection was a bit odd in that it did not work when the RCA plugs were plugged into Tape or Line-in. It only works when plugged into Phono.

You will have to keep adjusting the sound level of your receiver and iPhone device to figure out the best combination of each, otherwise there will be some distortion in your speakers. Mostly my sound on the receiver is turned up and the Music app on iPhone/ipad turned way down. That works best for me.

This was an excellent purchase which I highly recommend.
