My point was that something in process of shifting production to China was lost but it could happen as well while moving production to Switzerland.

Your supposition is faulty. One cannot assume a problem that occurred as a result of producing a product in China would also apply to a product produced in Switzerland, because no evidence has been offered to support the claim.
Further, in the case of the Cambridge A3i, there was no shifting of production. It was always manufactured in China, although it was designed in England.
BTW, I did a search of this integrated, and apparently the diode problem was not uncommon.
I also cam across an interesting thread about a Cambridge Audio D-500 CD player that came with a fake torroid (a cover with no torroid underneath).
