Which DAC would fit me best?


I would appreciate any help that I can get, as I've been reading reviews of DACs for the past week and have no idea what to get.
-My budget is $400, I'd like to spend less, but let me know
-My headphones are BD DT880 '03
-My amp is a Little Dot MKIII
-I'm using my MacBookPro as my source
As far as music choices go, I like to listen to some modern Rock, Jazz, Classical; so a pretty fair range.

I know it all boils down to just jumping an picking one, but I'd love to see if anyone had any specific recommendations based upon my setup.

The DACMagic lifted my modest system beautifully, even right out of the box. Yes it's a fantastic bargain with features I can grow into. I've long been curious whether the 24/192 DAC in my player can be improved with an outboard processor and I'm happy to discover it did. Give it a try.
mhdt paradisea and replace the stock GE tube with a NOS Tung Sol equivalent for a more full range sound with better authority in the low end.
I have been happy with the Apogee Mini-dac. It could replace your amp as it includes one. You can find them for $600-800 or so.
