My experience with Loewe compared to B&O is that their is more disparity in their sets as with B&O : they are constantly changing the display behind the same sets. You can have a very nice picture quality, but you can also have a really low PQ if you weren't lucky enough.
A friend of mine bought an individual, and was VERY disapointed because he had a dark image, nothing comparable to the set in display at his shop... The technician came and said it was normal...
When you buy a B&O, you have a more constant PQ : what you've seen in the shop is generally what you get at home. But you will have some software issues with newly launched stuff...
The new Loewe Assist app for iPad is really good : you get a well-designed view of the TV schedule, and you can select to watch or record a program with the touch of a button. (I already have that with my BV8, but with a french set top box controlled by the Beo6, not internally)
