Yes the B&O elements can be connected with MasterLink (TC, HiFi System, Link-SPekers, etc...).
But some of their speakers (BeoLab 6000 and 8000 at least) habe a (B&O Proprietary-) connector for their connection to a B&O Hi-Fi or TV-system, as well as a phono line-in connector (mini 3,5mm jack).
So far I have my Ipod connected to an AUX-Port of my B&O HiFi-system. So could I do the same with the Airport express. This the way Apple is mentionning all the time.
But as I happen to have one set of speaker whihc are not really used any more (attached to ym TV, which I don't look at very much nowdays...), I was wondering if i could connect the Airport Express directly to these active-speakers. It will still remain the question, how the speakers will be turn on/off and how I can regulate the volume...
