I moved 10 years back from Germany. I took a BS2300/BL2500 which is since then running on tranformers.
I would not do that with a TV though. Yes you probably can make it work somehow, as Trip indicates.
Is it a good idea? For starters, B&O US will not be able to service your TV. I learned this the hard way with a phone I bough in Germany few years later.
Also, everything here happens through external cable boxes. The brands a different then what you are used to from the UK so most likely your STB will not support these. I doubt it can be upgraded since the US never has seen that model. So say hello to 2 remotes.
Personally I would say good bye for it, find a loving soul who will cherish it and say hello to a BV 7 MK3 sans DVD if you still can scoop up a deal at your new local dealer .....
How long will you be staying?
