I've settled on K 702s as my main headphones but I still need closed-back tracking head phones. I'm considering re-buying the SRH840s which I liked a lot but that's so boring. Does anyone have some photos of the SRH840s and KRK 8400s side by side? I can't seem to turn any up googling. The KRK 8400s look significantly smaller and I'm not sure if I would like that.
