It's a trend in modern audio....the 'consolidation' of luxury brands so that they can be milked for the Asian market. Sonus Faber, Audio Research, Macintosh, Luxman...and now Naim. The one thing you can be sure of is a more generic product, as an example, Sonus Faber is now a parody of itself, knocking out cheaper ranges at an ever vaster rate, while constantly talking about Italian roots.
Anyone with a realistic outlook realised Naim was going straight down the plughole three years ago. Production in China by the end of this year? A certainty. My guess would be that a few up-market products will be made in Salisbury, if they are very lucky.
