Bricasti M3 vrs Meitner MA3

OP you should have your dealer walk you thru all your options, that's what you are paying for! Also from what I've been told by not only my Bricasti dealer but by Bricasti themselves is that the Ethernet option is superior sonically to the USB option. Again confirm with dealer. Enjoy my M3 is just wonderful

Forget the laptop. The Bricasti sounds much better using the Ethernet connection. 
It is very simple once you get it down. Your dealer will walk you thru the process. 
Hardwire the Bricasti. On your phone/tablet download Mconnect or any other UPNP ( universal plug and play) app. Make sure they are on the same network. 
Subscribe to a music service. ( Tidal and Qobuz are very popular). When you open the app it will discover the Bricasti. You will then sign in to your music service and you will be jamming and creating playlist in no time!!  

Thanks so much for the explanation. Already subscribe to Qobuz and love it! I guess the m Connect I'll have to explore with the dealer. When all is said and done, hoping I can use the Laptop (on a table next to me) via Hard Wired Ethernet to stream qobuz?   Just spitballing as we speak. Thanks

If the laptop and Bricasti are on the same home network you should not have to hard wire the laptop to the Bricasti assuming you are hardwired to your network using the Bricasti Streamer Card.  The application on you laptop should find your Bricasti assuming your laptop is also on your network(wired or wireless).  I moved to a dedicated  music server (Small Green Computer i5)hard wired to my network running Roon streaming my own music collection as well as Qobuz.  Works great and can stream to any system in my house as well as away from my home ie cars, boat, walking what ever,

OP:  @testrun is correct, you dont' HAVE to use Ethernet on your laptop, Wifi has plenty of bandwidth unless you are in a dense neighborhood.
