Hey guys, I am looking for amps (and DAC as well actually) to get the most of the HE-400 without spending a ton of cash. I know people mentioned that the E17 does a good job but I am just slightly skeptical because I heard from some that these cans do scale pretty well as well. Which AMP/DAC combo should I go for? O2/ODAC? E17 itself? M&Ms?
Or some options I've seen on Ebay here:
