Serge-

I have the built-in WiFi option on my BDP3 so no ethernet cable necessary. I will however run an ethernet cable from my computer to the BDP3 when moving ripped CD's to the Bryston's internal drive. What might take six minutes to transfer via WiFi takes less than two minutes via ethernet. A 50 foot cable is connected to the computer upstairs, tossed over the balcony, down the LR cathedral ceiling to the stereo. Needless to say, not a permanent thing.

Controlling the BDP can be from any computer on the network.

As far as Qobuz, the sound quality (through the BDP3) is very good. There are times it will outshine a ripped CD and there are times the ripped CD is better. As always, recording/remastering dependent. One can use the app (pretty slick BTW) on their computer to add albums to a favorite list and these will show up immediately in the Bryston software.
As you know, the Bryston interface is not as visually slick as some others but it's stable, extremely functional and nice sounding. A new version is being worked on with additional Qobuz integration and their customer support is second to none!

I did try ROON with the 60 day Bryston trial. Initially, the core, server and control were done via WiFi on a laptop to the BDP3. Integration is seamless with the Bryston but the sound quality left a lot to be desired. Moving the core and storage to a desktop connected to the router via ethernet and then using the laptop just for control improved the SQ but not to the level of the BDP3 alone. I suppose that building a ROON only device using a NUC and connecting all together via ethernet would help. Others have had improvements by adding various "audiophile dingleberries."

ROON is a nice software that integrates well with the BDP3 and Qobuz but I prefer the simplicity (and SQ) of just the BDP3.

Hope this long-winded what ever is of some help.
