Upgrading from AKG 712pro?

[Things change I've changed]

Currently my main cans are the K712 pro's, I have only just recently noticed that the HE-560's can be had for only £383 at the moment, just wondering if they will be much of an upgrade? what can I accept going from the K712 to the 560?

Any other recommendations? @ £383 surely they will be hard to beat for that? I know some might suggest the HD650 but at their current price I don't think I can pull the trigger on those and for some reason I just think they will be too warm/veiled for me, Z's sound demo on youtube put me right off them.

Edit -

My amp is the Audeze Deckard.

Just get the HD650 mate. They are my only headphone and you know how many pass by my hands. They are tonally the best I have ever owned.

The only other ones that tempt me at the moment are the Beyerdynamic Amiron.

If you enjoy the sound of the K712 and don't relish the thought of the much warmer HD650, then the HE560 should be a good fit. They have good bass, superb mids, though not as rich as the HD650 and some decent air in the highs - Personally I would snap them up for £383 if I were in the market for a new pair.
