Without amplification? It will run, contrary to tons of belief. I've ran it from a cellphone. It's better with an amp. But I think there's a lot of misinformation that this headphone needs serious power to do well. The Fiio E10 seems to power it just fine to my ears, let alone something more powerful (yes it sounds a little different with higher powered sources, but I think it's overstated that it's necessary to sound good).
