Yesterday evening I got some answers from my dealer.
According to him there is no possibility to change volume on the BS5 if the speakers are connected to the tv - as in my setup. My old BC2 had that ability.
In my opinion the BS5 falls, when you have to use both the remote and stand beside the machine to change songs.. Then Im back where I began - with the Ipad and B&O remote.. If you have the speakers connected directly to the BS5 then you can change the volume on the BS5.. Then I need to have double speaker setup - in that case one of the ideas of B&O falls.. It is not my intention to sound negative, it is the way Im thinking and talking to my wife about this.
Another thing that irritates me is that there is no possibility to do anything else than just skip to the next song on the beo4. You have to stand beside the machine.. My dealers idea was to buy the app for the BS5. But then Im back were I started - using the iPad and the remote. In that case I can go back to my old setup - BC2, Mac and iTunse. Shure I loos MOTS witch is a cool feature, but in my opinion it is not so great that its worth it when the system is controlled like the old system - only much more expensive.. Shure BS5 is a cool machine and all, but I dont need to show off..
Perhaps there is better controlability if you use the Beo6 - if that is the case the dealers should tell that to the customers..
Regarding the a.aux input - usb, you need to have the thing that B&O recommend to get it to work. - Actually no biggie..
And since we now end up at the same place as before we bought the BS5, I will try to trade it back to my old BC2 - a masterpiece on the wall :) and having my iPad controlling my mac..
