STORY POSTED 30/09/09:
"We have recently been alerted to a problem of cracks appearing in the casework of some DacMagic power supplies after a period of sustained use," says CA.
"We believe this only affects a small number of UK PSUs, however Cambridge Audio has taken the decision, as a precautionary measure, to replace all UK DacMagic power supplies."
Owners will be contacted in the next week using the details given at the point of purchase and a replacement PSU will be provided free of charge. This will take a few weeks.
In the meantime, you should check your current PSU for any cracks or signs of damage. If the casework is damaged in any way, switch off the mains at the wall socket, unplug the PSU and do not use it again.
CA says this problem only affects UK power supplies, and not those sold in other European countries, Australia or North America.
If you do not hear from Cambridge Audio by November 15th 2009, you can contact the manufacturer directly using the online form available on the company's website.
