Nice, I'm still waiting on my custom Roxannes, 3.5 weeks out n counting. In the meantime I picked up a bargain pair of new HD800s for the Chord Hugo so I'm busy burning them in. My Hugo just ran out of batteries so I connected them up to my Teac UD-H01. Big difference in sound, the HD800 really do scale and you can pickup what's in the chain. Oh well, these'll keep me occupied until my Roxannes arrive, hopefully soon.
Keep us posted how the AKR03 changes further, I'm sure they are nowhere near fully seasoned yet.
