Lumin U2 Mini

I’d have to give the nod to the bluos app over the Lumin, but only slightly. Then again, the app was the best thing about the Node I owned. SQ goes to the Lumin for sure.

OP, I tried the Lumin U2 Mini for a while but found the app difficult to use. Switched to the most affordable Aurender (N100) and never looked back. App is more user-friendly and sound quality superior in most ways. I've yet to hear of an Aurender user who disliked it, whether top, bottom, or middle of the line. My guess is if you're upgrading, start with Aurender since you will almost certainly end up there.

1. It would be highly recommended that the music files be moved from the vault to a Nas or somewhere that has redundant storage.

2. My NAS runs the basic UPnP server to index and manage the music- the metadata, tags, annum art, etc.  

then my Lumin (a D2) streams the music, and the App does the controlling   
 

I’ve seen some people that don’t like the app, but once learned, it’s good.
 

All Lumin  hardware use the app 

The U2 mini looks like ice kit. 

I'm surprised nobody has mentioned the availability of Leedh in all Lumin products. Using this lossless volume control can eliminate the need for a preamp and judging from the reviews the Leedh is more transparent than any hardware volume control.
