Congratulations!! They are GREAT cans...the best I've had.
I sold mine a while ago...they had (for me) a fatal flaw: TOO open. There were too few opportunities to listen where I wasn't either intruding on others, or they on me. One of these days, when the kids are spending more time out of the house, maybe I'll find another pair.

I'm curious to hear what you think with the Woo Amp...
