This will be my favourite picture for a long time. I've since sold off Eikon and Atticus. Not because they didn't sound good but because I'm using HD800 primarily now. It just sound so right to my ears with Glenn OTL amp. Headphones are such personal gear. Much depends on preference and partnering equipment.
L to R - HD800, LCD-2f, Atticus, Eikon.
Makes me want to buy three other nice headphone stands like those and take a similar photo! I really want a Padauk Eikon.
