Thanks all.

I'm confident Meridian/dealer will sort. Just hope it's not going to be too much inconvenience and things can be sorted without having to make special trips to dealership.

The lack of decent USB power from PSU is a shame - a non orthadox configuration but would have made a really convenient connection method without the need for an extra mains connection.
