Kw13, once you're caught there is no going back. And that has nothing to do with having read threads like this one on the subject. I take my own case as an example, but you can also read a number of other people's stories that didn't even know the name until they heard them for the first time, immediately fell for them and were prepared to break the bank to get them in their system as soon as possible.
The unfortunate bit in that last statement is the "didn't even know the name", unfortunate for an interested audiophile, that is. As you correctly pointed out, there are very few reviews. John Potis's review on the Piano (classic) on 6moons probably was the first major one. In their native Germany, there are none at all until this day. Let's just assume this has nothing to do with systematically ignoring the brand for fear it might ravage some existing elite (well...) but only with inexistent advertisement budget (I've seen one ad by the dealer and I do read a lot) and extremely thin dealer network in Germany. As pointed out by the previous posters, these speakers are in fact made on order. In any case, that is why it is so important that at least these "love fest" threads exist: grassroots information upon which everyone can then either continue to read, search, attend show performances, audition ... or not (this is not religion, we're not here to convert anyone).
Sadly, the content of these threads must also tell you something about prices that are to be expected. Let's be realistic, to achieve Tidal's quality benchmarks in terms of sonics and build quality, research, custom made parts, craftsmanship all have a price ticket. Very unfortunate for all of us, rest assured I couldn' t agree more, but we all know other examples of that. Outside of Germany, add shipment cost, distributor's (healthy) margins and their advertisement outlay. And since there is nothing to be found in the used market ...
Will these speakers be bettered as you suspect? Well, other people already have elected another own best anyway, and Tidal aficionados (or cognoscenti, if you like ;^)) may find future Tidal series to outshine today's one day. As per today however, you have stated the most important thing: find a way to hear them and be the judge yourself. Warning: you may find yourself wanting to have some and even relativize the price (in all honesty, I've heard more expensive speakers that didn't stand a chance).
Hope you find an opportunity to listen soon!
