I think the "I prefer made in Britain" thing is mainly down to companies now holding lot's of brands all made in one factory, I own an original pair of Castle Richmond 3i speakers when Castle acoustics made the speaker in Britain from their factory, the company has since been taken over to work alongside, mission, wharfedale etc.. the last pair of speakers made by Castle, the knight I believe ( I did try them before this 3i) is no Castle speaker, it may have the name but not the quality, the difference in build for starters is startling, honky cabinets & poor sound when compared to the original Castle cabinets which feel as though they should be sitting with a £1000 price tag instead of a £330 one.
This is the problem that faces manufacturers & buyers, buyers think they are buying a certain brand but are they, with this example, the answer is an easy no.
The last decent Mission speaker was the 780, built in Britain before the takeover to the far east.
As usual it is quantity over quality with the original speaker having the same low price tag but a much superior build & sound when built at their UK factory, they were cabinet makers before making speakers & obviously this talent has not been passed on to the new Castle speaker makers.
After my experiences I would certainly choose "made in Britain" over the far east option. It doesn't even keep the prices down as this proved, the Knight came in at £300 originally before the company realised it wasn't even worth the new £150 price tag.
