Ah, OK, just read all the way through the covering email (note to self, always read right to the end) and I see what the issue is;
Please note that due to their design, we cannot offer a service on the products listed below. The risk implications of damaging the internal boards are too high and given the value they hold, it is not worth damaging them beyond repair. We are still able to repair these products and will continue to support the owners.
This applies to CD555, NDS, and Superline. I’m guessing there may have been some unfortunate incidents that occurred?
