No, these are stereo, 2-channel, headphones. I have K701's. They don't require an amp, so you're good, but If you want an external DAC/Amp combo to get the best these headphones can do, then the Schiit Stack (Magni/Modi combo) is a great choice. You'd run the DAC with optical out. Lastly, yes the Antlion Modmic.
