Sometimes it is even difficult to know the current product line.
A few weeks ago I walked into a B&O shop after requesting a Beosystem 4 demo on the shop's website. The owner of the webshop greeted me as I entered the shop. I told him that I was here for a Beosystem 4 demo. He replied Beosystem 4...? What is Beosystem 4 - We do not sell anything called Beosystem 4. I tried again, yes you do. Beosystem 4 the stand alone box containing Beosystem 4. Then I asked for the person I had been communicating with and got the demo...
That would be the BeoCenter 4 you wanted a look at, then. But they should have been able to figure that out.
