The Imperial DABMAN i400 can be connected to any stereo system (amplifier) or sound system without any problems (use AUX inputs), including the B&O (provided there are still free AUX inputs). This can be done via the usual chinch plugs.
This device runs excellently and that via WLAN or LAN. I have connected it to the LAN and have noticed this deficiency in not finding the LAN from time to time. However, this could be due to certain routers establishing a new connection from time to time (network address is reassigned).
Imperial DABMAN i400 also offers the possibility to control the radio via mobile phone, portable etc. for Android devices (APP can be downloaded from the website).

Have fun with the DABMAN on your B&O system.

Unfortunately, I don't know what connections your B&O has.
RCA would certainly be good, 3.5 jack also works with an adapter.
I'm absolutely satisfied with it, even if it doesn't always recognise my LAN adapter immediately...
