I do not think B&O have lost their mojo at all. I think the pure external design of any of their products is easily recognisable as B&O (bar the link equipment) from the 70's through to the current day.
However, there are some instances whereby the ability to design something unique is rather challenging - flat TV's being one and MP3 players being another.
If you look in terms of functionality and control, then there are products which stand-out more than others. All the ATL loudspeakers come to mind here - which is truly revolutionary. The BV7 in terms of its functionality is way better than the Avant (which the CRT had 40 years of development to rely on). Even the Serenata (which I absolutely love for what it is and does rather and what it does not do or pretend to be) has mojo. Then there is the BC2 which is fresh technology and not simply a reshaping of the BC9000 series products. In-fact, looking back from the late seventies to date, there are only one or two products throughout that a time that were revolutionary (i.e. at no greater frequency than today's revolutionary products). Many of the Beomasters, Beocords, Beocentres were reboxed over time with slightly different interfaces and with small incremental improvements or simplifications. The BC9000 for instance, is fundamentally the same control interface (and similar internals) from 1987 to 2000 over 5 products.
I guess ultimately, and as read this continually on this forum, people want B&O to be like this product or like that one or have a feature that is the same as Apple's etc... which no doubt leads to disappointment when B&O don't copy, don't follow the mainstream or do something in their own way and gives the perception of a loss of direction.
