I had good year last year at work, getting a pretty big promotion/bump in salary + an crazy ass bonus last week and I decided to spend some of it on a little setup. I thought about getting the HD800 but I def didn't want the mrs killing me when she saw the price tag on those so I stayed with the HD650s and added the WooAudio 6 Amp.

EDIT: Just hooking things up today, so hopefully I'll be back later with some initial thoughts. This should be a nice upgrade from my HD595s which have served me well for a number of years.
