I would say Mojo treble is tame but rolled off too soon. Never harsh. Grain, maybe, but it is quite difficult to scrutinize Mojo treble because it is so recessed compared to its bass. Nevertheless, I thought Mojo treble was fine, until I own Momby. I didn't even need to A/B to notice the difference. Anyway, I really really counting on Jotun to be a more musical version of Valhalla 2 while retaining the qualities.
