@lanodan @vidister @wolf480pl yeah. But again, this is the territory where you literally have no idea whether deranged audiophile forum posts actually have a point or if it's just total lunacy.

Like, I remember there was a post claiming that flashing Japanese firmware instead of EU into Sony DAPs makes them sound better. And what do you know?! IT DOES! Because EU places limitations on max power output into headphones, thus gimping sound quality (also loudness, but lower freqs are perceived as more quiet given the same power output, hence quality stuff) especially with high-impedance drivers.
