Looks like somone else has designed a bracket then - nice one Paul.
The one that I once owned was much more substantial than this version as it was made from good quality sheet steel and required the removal of 3 screws form the front of the beocenter to attach it in situ. A real nightmare to do by myself as the beocenters are very heavy and not the easiest thing to manipulate when they are only half held together- but I eventually managed!
Definately NOT an official B&O product BTW - I previously mentioned the 35 degree angle which is about the maximum angle these beocenters will accept and still be able top play CD's. I believe the 9300? has a clamping mechanism to hold the CD in place which would in theory allow you to hang these totally vertically.

The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
