Update on the Focal Elegia / HipDac combo..
Having had the brand new pair turn up and burnt in, with some generous EQ these things are really good, the soundstage is so wide for a closed back, the imaging, clarity, separation have all improved as me and the headphones have burnt in.
Some headphones react well to EQ, some don't.. These IMO have been transformed, just the right amount of bass (I'm a bit of a bass head) without bleeding in to the mids, and with a bit more top end gain it's really opened up the airyness and detail (to suit my aging ears).. very very happy currently, just about everything sounds 'better' and I am struggling going back to my other headphones..
The new pair has a much nicer cable supplied (The original woven/braided affair is too stiff, the new cable is similar to the Elear) so I've resisted the urge to upgrade to balanced just yet!
