Hi Pavel.
I respect your tastes which are not necessarily mine or that of others.
So let's talk about other tastes and other people who are familiar with Kennerton headphones (and others totl headphones), too.
Pierre Paya (french importer of Kennerton products), prefers (quite clearly) the Thekk to the Thror, which is his favorite open planar headphone (all brands of open planar headphones combined:Audeze, Final Audio, Meze), just after the Hifiman Susvara.
Former Kennerton engineer Max preferred the Thekk to the Thror for sound (and listening pleasure). And this is not a development and casting error.
The Thekk was developed by Kennerton after the Thror, taking into account the experience gained with the Thror.
The Thekk was designed to be different from the Thror (with which it shares the same "carbon" planar driver) to make it more euphonious and pleasant to listen to than the Thror, whose austerity of sound and lack of flavor, even coldness, could put off some.
Certainly, the Thekk, more colored than the Thror (more colorless see insipid), does not have the same degree of coloration and flavor as the Odin (even more colored and tasty in the medium than the Thekk), but it largely exceeds it in terms of technicality: aeration of the sound scene, precision, speed, distortions, without counting the difference in weight and comfort between the Odin mk2 and the Thekk (day and night between these two headphones).
I gave to a friend my Odin mk2 that I didn't listen to anymore compared to the Thekk that became my main headphones.
The Odin mk2 being for my ear too colorful, not precise enough, not aerated enough, a little slow in the bass, and even too heavy to wear on long listening periods. Moreover the treble of the Odin is too grainy, not fine enough.
The Thror's treble is better, but I find the Thekk's even more refined.
Above all, what I appreciate the most about the Thekk compared to the Thror, two headphones of the same technicality, in addition to the slightly superior aeration, is its extra mid bass and the fullness of its timbres, denser and more consistent than those of the Thror, which does not give enough body to voices and string instruments.
All this, of course, is my personal assessment of these three Kennerton headphones.
To conclude, Kennerton's ex-engineer Max jokingly said, regarding the Thror and the Odin mk2, that he would use the Thror for work (for its Germanic rigor), but that he would use the Odin on weekends, for fun.
Well, in my opinion, I don't use either of these two headphones on a daily basis (although I know them very well): I only use the Thekk, and every day of the week!
The only headphone that might change my mind (if I get it) is the Rögnir.
