I was looking into the Music Streamer II USB DAC and I was wondering if I can plug my Grado sr325is headphones directly into the DAC without using an amp??? From what I understand the Grado's are easy to drive but I don't really know how much power the DAC outputs.
 
I can't really afford to buy a separate DAC and amp, my budget is around  $150-200. I would prefer to buy the DAC separate if possible so I can use different amps in the future.

No, most line out have DC offset which while some headphones can with stand for short periods, will lead to the eventual destruction of your headphones. Also loading a dac output with a low impedance grado might not be a good ideal.
 
Also I suggest buying a amp first.
