I heard that the speakers you buy in the UK (specifically Beolab 5's) have power supply units that have auto-switching between 100 ~ 240v.  Can someone confirm this?  Alternatively, how much does it cost to get a PSU changed in a typical B&O speaker?  I am moving internationally from 230V to 110V jurisdiction and wanted to know what pains I would have having bought all of my equipment in the UK...

Thanks
