I second that. DON'T Start buying crazy expensive Amps/DACs looking for a big change in SQ, you won't find it. A better way to start tweaking the HE-400 is with the easy recommended Mods, well documented with step-by-step guides. OR, search this thread for EQ ideas. The HE-400 will response to both. AMPs/DACs are really about two things: features and power. Get the features you want, and the power you "need". Any SQ benefits comparing amp to amp are usually too slight to base a decision on (unless there is a problem, or serious difference in specifications). You have more than enough power for the HE-400 already, and a great DAC. If you are getting the amp itch, try reverting back to powering the HE's with a Mp3 player, Phone, or basic computer. Then plug in the Schiit again. I am sure that will help.

Taker - What is your source and amp? I honestly assume that you are either pulling everyone's leg, or you have a system with severe treble roll-off. Then again I don't have a lot of content that really REACHES well into the upper reaches, so the impact of that EQ profile is probably slim. Why don't you also Boost 5-20 hz about 10 dB and try them out?
