As a follow up to those interested in adding streaming features or a music server to BS9000 and similar devices, this is what I came up with that works wonderfully.

The trick is what the vintage B9000 can accept signal wise.  Remembering that external inputs to the B9000 have to be fed through the A.Aux socket, the easiest way I found after much searching to set it up like I wanted was to use a Nativ Sound Vita as my digital device to stream to the Beosound Core which acts as the digital/analog converter.   My core is not near my BS9000 but in another room near my router. I'm sure Sounds Heavenly has a single cable to connect the Powerlink out on the core to the AUX in on the BS9000 but I didn't realize it at the time when I was at the B&O dealer trying to get help on putting this all together.  B&O doesn't have a single cable to make this connection.

The Core can connect back to the B9000 with an analog signal from the Core's Powerlink output via an adaptor to RCA/phono style plugs that can then be connected to the B9000 via another adaptor going from RCA/phono to the DIN -A.Aux socket.  Everything worked like magic.  If you decide to go this route, here are the B&O parts you will need: 1)BeoSound Core; 2)B&O Cable Powerlink RJ45 to RCA Phono 2m long SKU# 6271265 ;3)B&O Adaptor BeoLink Active AUX Input DIN to Phono F SKU# 6270302.   Positives to this are the connections work for the B9000.  Negatives are the costs for the Core and adaptors.     

One other thing that isn't well known about the AUX socket on the B9000 is that it will take input and provide a line out at the same time via other pins.  I use this feature to provide music from the B9000 to other parts of my house. The connector has to have four connections adapting to the din plug to give one both in & out signals depending on the different pins in the socket.
