Your comments are interesting insights, as always, Andrew. But is this really a new phenomenon, for TVs, or vacuum cleaners for that matter? Colour TVs cost a fortune when new, and were useless really, constantly out of alignment, breaking down, enormous. Just like 3D tellys then! Ditto the early plasmas, which cost £3000 or more, but now seem ridiculous.
Panasonic and Sony, to take two premium examples, don't have to make TVs at all. If they make no money then more fool them, unless they are loss leaders for some other product or service (though quite what, I'm not sure with bluray players for under £100).
If Apple made TVs (as opposed to the confusing Apple TV box) they might look like Loewes or B&Os. They cost a fortune too, and presumably low volume. Which brings us back to the topic, because Linn is very low volume and very expensive.
I think most of their current products are over-priced, but they are pretty fantastic too. The LP12 aside, as it will forever be controversial, the Klimax DS is stunning. I could never justify one, but I am glad they exist, that Linn are still in business after 35 years, and are British.
