In spite of the "great bargain" this represents, it makes me seriously question HiFiMan company's commitment to anything in their namesake, namely Hi-Fi, or as we used to know it - High Fidelity. The specification says 20 to 20 khz, and when you say it's obviously colored and not flat, that says to me that the dips in response must be at least 3 db around 50-100 or 5-10 khz, to be obvious. Now with that much dip at those frequencies, how much greater would it be at 20 hz and 20 khz? 10 db maybe? That's not just colored, it seems like a bad joke.
Some of the comments at Amazon say the line out is cleaner and better than the headphone out. So maybe that's the problem - a really bad headphone amp.

I'll put something up tonight when I get to a real computer. Thanks for the feedback.
I'll check out the Line Out tonight and see if it makes noise. YouTube commenters are saying the audio player HiFiMan makes also makes hiss noise. This was my first HiFiMan product and I am surprised that he let this flaw out in the wild.

I have one of these, and while it improved the sound on my monoprice headphones, I got so much interference from the wifi while using it with an older MacBook Pro, that I had to take it to work and use it to assist the logitech desk speakers the company was willing to pick up from Staple.
On the macbook, even with wifi off, I was getting a low hiss when I wasn't playing anything through it. With music on (in both the headphones and the fairly cruddy speakers) it managed to bring out little things that I wasn't hearing otherwise, as long as I wasn't dealing with wifi interference.
I would offer more, but I'm still trying to put proper terms to what I'm hearing as I'm just starting to audition different things.
