I have recently bought myself a pair of Sennheiser HD820 headphones and I am currently running it of a small Audioquest Dragonfly Cobalt (PC). I am trying to save up to get myself a proper headphone amp, but I am still undecided either to go ahead, or what to buy 
Who else have a pair of 820s here, and what are you driving it with?
