Works fine with Up2stream mini V3

Marvin Ochieng
Hit and miss at the same time

I primarily bought this device to simply my audio experience.

I mostly listen to internet radio and stream from youtube (audio mostly) and this looked like the device that would help me find the balance between good audio as well as streaming device.

The audio part works well without a problem. The only problem is the stability of the hardware in relation to streaming. The device doesn't play all streams consistently. There are some which are unfortunately my favourite that will play depending on moods I guess. There are days when it can go an hour without cutting off otherwise I normally get max of 20 minutes before having to restart.

This has made me almost go back to my previous set-up where I play the audio through bluetooth which kind of beats the purpose and the main reason why I went for this in the first place. In future versions, it would be good if emphasis was put on reliability other than anything else.

Another problem the device has is obvious lack of documentation. This pours cold water on the overall experience of having it as a DIY speaker as all you can do is play, pause, etc.. the simple functions you can do with your normal bluetooth speaker.

The API response is also another problem. Because there's no way to put it on standby through the HTTP API, I am forced to power it off since I'm running it off battery. There's no guarantee it will connect back to the home wifi. When it doesn't, using the HTTP API to configure connectivity again is trial and error so today I gave up. moved it permanently to a place where it can be connected to wired LAN .

Overall, this device can be a good bluetooth, USB player but not-so-relialble internet-streamer. This has made me start scouting for a more hackable and reliable adruino or PI set-up.

Performance VS Price

Up2stream 2.1 is excellent product for 2x50 plus 100 watt sub. Control app should upgraded to have complete remote function. Price is very high.

I bought two Up2Stream Minis, one with a DAC board and the other with an optical line-out board. I thought that they would need a bit for work, which I was happy to do. They were both up and running in 5 minutes! They are reliable and stable unlike much of their far more expensive competition. They even tell you when they are connected to your wi-fi network. I have used Amazon Music, Apple Airplay, and Spotify, all with no issues. Now, Arylic, all I need is some nice cases!
