I also think BeoLink Wireless is used at 10% of its capacities.
Indeed a Masterlink wireless would have been a right step forward, this would have enabled products like the BeoLab 3500 to be connected with a single cable instead of the cable mess we have to deal with (Powerlink, + another separate IR eye).
I also think the audio signal transmission should be digital: all audio sources are digital nowadays, except for FM radio).
Having the receiver built in the speaker would be logical to me, maybe not for main speakers, but at least for the BeoLab 3500 and for a new range of BeoLink Wireless speakers: instead of launching a BeoVox 1, why on earth didn't they design a Wireless BeoLab , like a BeoSound 3 with built-in Wireless & infra-red receivers, a different control panel on top of it, a large display like BeoCenter 2's, and complete portability to use the wireless options everywhere you go?
I use wireless speakers in my bathroom & kitchen, both use the 900 Mhz technology which is much less jammed than this 2.4 Ghz everybody uses, I get excellent sound without wires, and just need to put a B&O IR receiver in the rooms where I want to control sources.
The 2 speakers cost me EUR 99...and you can use them as mono speakers like on BeoSound 3.
I also believe they should integrate the Wireless transmitters in the main systems, this would help reduce the cable mess that these "wireless" systems eventually produce!
