AH-D5000s arrived today. Freaking Amazon, knocks it out of the park again. Two day shipping somehow arrives next day, wasn't expecting these till Tuesday.
Pre-break in impression: I'm very pleased. The low end fill I was missing with the K702s is immediately present. While not providing the same clinical nature as the 702s, these bad boys already sound great on my favorite tunes. Can't wait for these to be broken in properly.
In fact, they already sound much better on my Icon HD (amp/DAC) then directly out of my HP-4. The HP-4 has four jacks so I had to compare them to the 702s side by side.
Thanks to everyone, especially MalVeauX. You've steered me in a good direction. Think I'll take that extra cash and apply it towards a Lyr/Bifrost before I start looking at planars again.
