Thank you for that, Dennis.
I've tried several colors of the speaker cover. I definitely think the blue is stunningly beautiful and also more discreet and confortable for the viewing experience (compared the white speaker cover for instance).
That's a very good questions. It's like choosing a favorite among your children – you love them all in their own way.
Depending on the size of your living room I would go for the BV7-55 (assuming you got the space for it). Otherwise the BV11-55 is a masterpiece on the wall and saves space in the most elegant way possible.
The picture and sound experience is truly amazing in both BeoVisions, however the sound in the BV7-55 speaker is superior. I don't think neither of them are outdated – not at all! First of all 4k doesn't make much sense on a 55" screen, and if you add an Apple TV with puc code to enable B&O control you got all the smart tv features in the world – at least the ones that are useful.
To make a conclusion I would go for the BV7-55 if you own a lot of MasterLink products, but if you mostly own NL products I would go for the BV11-55.
PS! Please promise me that you will never buy BV14. This is the worst POS I have ever owned. I actually "downgraded" to the BV11 when I moved. It was such a relief to return to the amazing B&O UI etc. .... It just works as Steve Jobs would have said.
