Thank you all for good answers!
I've decided to stick to my two set-ups, as I'm extremely happy with the fact that Playmaker fires up my BL5's as soon as I hit the Play-button on my iPhone/AirPlay.
From time to time I miss more powerful sound from the TV speaker. But the BL10 is quite good. Of course an extra set of Beolabs connected to the TV would be awsome, but my wife would kill me then...
Do you BeoExperts think that it could help to change the BL10 for a BL7-6??
