Hello everyone.
One hypothesis, to explain the difference of FR between the Odin mk3 (which is actually an Odin Thridi, according to Kennerton) and the curve of FR published lately (on RAA) for the Odin Thridi (in this case, a superb Odin Thridi "brand new" in Karelian birch): well, it is precisely that the latter Odin Thridi appears on the site RAA as new, ie not burn-in (or insufficiently burn-in) compared to the Odin mk3 (hypothesis ).
However, I have the impression that the Odin Thridi (and the Thror) not burn-in (new) are restrained in the frequency response, both in the sub-bass (which are initially restrained and which expand by the continuation with burn-in), but also in the treble, which extends and is also released (unfettered) with burn-in.
It's at least the impression that I had with my Thror at the beginning (and also with my Odin mk2 at the beginning) when they were new (not burn-in) (treble and low was perfectibles at the beginning, like restrained, not extended, and lacking fluidity).

Odin mk3 (early Odin Thridi, with the chevron grids, distinct of the Odin mk2 grids, because here in composite material, and not in Zinc like the Odin mk2).
Odin mk3 here burn-in (hypothesis) for the measurement curve of the FR on RAA.

Odin Thridi (here in Karelian birch)
Odin Thridi new (no or poorly burn-in) for the measurement curve of FR on RAA (hypothesis).
