Welcome to the forum PerT.
As you may have already discovered, all the information has been relayed here:
Naim also informed their dealers and distributors on the Monday so they could pass information on to their customers.
Lots of help being offered here as well by the members and also by myself and Steve Harris. Otherwise there is your dealer and also Naim support via email or phone.
