I have been a bit too broke for this stuff but the Edition X looks stunning to me. Prob the best looking hp out IMO. I called myself saving up for the Odin but some reports have me deterred. Also I am deterred from the Dharma because I want nothing close to thin. I sold my other gear for speakers and dont regret it, but I am missing a high end open back.
I'd save for this instead if it does the following:
HE 6 = bass quantity and impact
HE 560 < sensitivity
HE 560 < midrange quantity
A physicality to the music reminiscent of the 6 (of course it will be softer but please give us some weight)
HE 6 < soundstage
HE 6 > treble
HE 6 =/< treble extension
I'm sorry but the HE K is not reading like it's price. At 3G's it should be KILLING everything with ease.
Sounds like a dream wishlist. I doubt the HEX is what you're looking for.
With the except of bass quantity and impact, the HD800 (which according to your profile page, you've yet to own) would have the larger soundstage, better treble and far better treble extension and articulation, as well as more sensitivity and midrange quantity.
