    DAC to pair with Bottlehead Crack

    Hey guys n gals! I'm running with the HD 650's, Bottlehead Crack + Speedball and currently using my computers onboard DAC. I notice that it's not 100% quiet and I feel like it's holding me back a bit... So I'm thinking I could spend about 100-200 dollars on a separate DAC, what do you think?
