Good evening Guy, Thank you for your extensive answer. What I understand is that the Beoport or Beolink PC2 is usefull if you have a masterlink network and want to add a computer source. In nowadays scenarios (server music shared through wifi or computer out to speakers not using the now deprecated Beoplayer software) they are more convenient solutions. Am I right?

Yes indeed.  One of the biggest limitations of using a computer source is having to switch the computer on.  I added a NAS to my network once I starting moving to digital, and I am now happy using an iPhone to control what goes from the NAS to whatever B&O device (usually via Airport Express).  I suppose the original B&O  solution was the BM5, rendering Beoport/PC2 obselete.
