Hey I'm new to headfi and i recently decided that i would buy a DAC for my grados which i love. I am currently running from my 360 > optical > Astro a40 mixamp (2010 edition) > grado 225i. I prefer an edgy, but detailed sound to my music and i listen to mostly rock. I was wondering which DAC (or amp) would benefit me most for about 300-350$ (willing to push to slightly over 400$ if it really makes the difference). Thanks for the help from the professionals.
