Jeff Fritz from Soundstageultra wrote a article about loudspeakers for both luxury and performance
"But as exalted as all of these qualities are, they alone wouldn’t have gotten Tidal on my list. Tidal stands at the very top of the industry for its promise to perfect every detail, down to the most microscopic and seemingly least consequential. Their build and finish qualities, inside and outside the speaker, are the best I’ve seen on any audio product of any type.
No part of a Tidal product is less important than any other part -- that’s not the Tidal way. Their top model is the La Assoluta ($625,000/pair). This 1069-pound jewel must be seen in the flesh to be believed. The same could be said of its little brother, the Akira ($255,000/pr.). I could go on and on -- suffice it to say that you probably haven’t seen what’s possible in precision loudspeaker design and manufacture until you’ve been in the presence of a Tidal loudspeaker."
