Why do you find that strange? EU tax is not applicable to buyers outside of the EU.
Non-EU buyers are likely to be taxed at the applicable rate to their own country, when the CIEMs cross the border into their country.
Fair enough. Obviously, it is still a 5-way, but I was anticipating that the price increase might be indicative of some doubling of some (not all) of the drivers (maybe the tweeters, for example). Having owned the standard SE5, I already know how packed it is with the existing drivers (SE5 woofers are quite large).
I adjusted the contrast on the SE5U pics and they are certainly every bit as crammed as the SE5, and
maybe more, but almost impossible to know for sure, with just pics and no actual CIEM to look at in my hands.
