So I've been listening to these for a couple of days now.....
Thanks to all you good people for the suggestions, help and comments.
The A-T ATH M50's still not completely broken in, but I like them very very much. They are getting better and better.
The Fiio E 10 DAC/headphone amp is a nifty bit of kit. I haven't decided on a player yet, for playback, but I have done some optomizing of the playback settings on my XP computer bypassing Kmixer, etc.( which means I'm still using Windows Media Center for now ) I don't have any experience with another DAC to compare it to, but I think it sounds very good. It was also dead easy to set up, Windows recognized it, all I had to do was make it the default player.
I'm trying to decide between learning Foobar 2000, or JRiver media center. I need to rip some files and play with both of them.
Thanks again gents.
John
