Good Streamer with WiFi Connectivity

I can only speak from my own experience with the Lumin U1 mini... The Lumin App works with iPhone & iPad... Also is a Roon RAAT endpoint and UPnP for things like Audirvana... Can have local files on a jump stick and PC library backends and Synology NAS via Minimserver... It just works and sounds crisp and clean to my Chord Qutest... Good luck with your choices...

Hardwiring via ethernet is strongly recommended. I tried "wireless" and have a very robust network....there still were dropouts but none wired.

Auralic designed the Aries G1 for wireless operation and recommend it over an ethernet connection.  The Airies also has twin linear power supplies while I believe the Lumin U1 Mini only has a single switched power supply.  I've never heard the Lumin, but I'm sure it sounds very good.   It's just that the Aries offers a lot for your money.  I have the older Altair and it sounds excellent wirelessly.  BTW, Auralic's Lightning DS operating system is actually only compatible with an Apple product.  Have fun in your search.

Never had an issue with wireless. No drop out, no noise. I still use an Auralic Aries LE for this very reason.

I've owned the Aries Mini, Aries Femto and the Aries G1 and have never had a problem running any of them via wireless and could never tell any difference in sound running them wired.  Also have owned a Lumin and the Teac NT-505, which runs off of the Lumin app.  Both apps are very good though different in their approach but I personally give the edge to Auralic's Lightning DS.  Both were designed to work their best with IOS.  Lumin has an Android version but it can be buggy at times.  Without a doubt the G1 has better power supplies than the U1 Mini.
