Thanks for all the input!  I'm just compiling my list - and looking for something to go on sale.  So the HE-500s, are they really THAT much better then the DT-880s 250ohm, HD600/650, etc.  So hard to decide without getting to hear each one.   I'm looking at that AKG 7XX and the DT-880s on MD. ...

massdrop has the MK2 for 169.99 + a bonus gold lion tube. Don't bother looking for one in the amazon warehouse. I'm returning mine, that is an MK1. They'll probably just try to resell it as an MK2 again.   Only problem is an est ship date of feb 18

  THANKS!  I've been using my ears and not my eyes to review this thing. I got one from Amazon Warehouse and thought I got a deal.  Looking at the box, it has a barcode sticker covering the original label they used which only says Aune T1 upgradec version - nothing stating MK2 on that label or...
