Here is what I think could work but some expert on this forum would need to confirm since I don’t have a Beosound 9000. 

1. Buy a Beosound Core and connect the Beosound 9000 as an input source to the Core.

2. The Beosound Core is Apple AirPlay 2 compatible so if you have an iPhone or iPad - the Core, the Apple TV  and the speaker in the conservatory (for lower cost I would recommend the Beoplay M5) will be visible as AirPlay 2 sources. You can now play anything from any of these devices anywhere.

3. The problem in your set up is that the Eclipse is not AirPlay 2, the Apple TV is, but it doesn’t know anything about the Beosound 9000. So basically all you are doing is making the Beosound 9000 AirPlay 2 compatible.

My 2 cents is that you should consider uploading your CDs (if they aren’t already available on Apple Music or Spotify) and just stream to the speaker from the conservatory since any BeoPlay speaker is not going to resolve the difference between CD and streaming quality.  

If I understand the question correct, the op already has the BS9000 integrated with the Eclipse.....probably using a NL/ML Converter.

If not, that would be the best way to do it.

OK - there might be other ways of doing this....like Jaffrey2230 wrote.

That linked setup will give you the option of linking another NL-device.

Depending on the needs (and what should be spend) a BeoPlay M3 in the concervatory would do the job.

If correct configured, this could draw on the CD-part of the 9000 as well as on the ATV connected to the Eclipse.

(Hereby note, that the M3 also supports AP/AP2).

For comfort, just use a BeoRemoteOne/bt with the M3 to control it and its linked sources.

That is wrong. Eclipse have airplay 2 support. :) Its wrong on the webside. 

• I thought the Eclipse was Airplay 2 compatible

You have it - just test it....should be easy enough.

Eclipse is Airplay 2 compatible....

Not sure how the B&O guy connected the 9000 to the tv but I know he didn’t use NL/ML converter

You connect bs 9000 to line in on the eclipse. 

Manual control BS 9000, and sound up and down with tv remote or app. 

You can also disturb line in out to beolink, to product that support beolink app. ..

Would mean, that you have to manually turn on the 9000, whenever you’d want to listen to CD from it in the conservatory........if you have an NL device (like the M3) there.

Not that comfortable, but will do the trick as long as noone else is using the Eclipse.
