Seems like the differences are tube vs SS than emotiva vs SS?... Can you compare the emotiva to a lesser SS amp such as fiio or Xonar STX?

Thanks for the impressions. The Emotiva always interested me because you could use it as an endgame amp, so while you're upgrading cans, you're set with the amp. I'm curious, how much travel is there on the knob? And at what point on the dial is a comfortable volume?

I don't object to the characterization of tubes vs SS, but I do think the Emotiva is a real step above my other SS amps. I have a JDS labs CMOY and an entry-level Sony receiver from the 90s. My CMOY clips with the HE-400 rather easily. As in at my regular listening volume (~80db). Below clipping, the CMOY has a similar flavor as the Emotiva, but separation, soundstage size, and bass definition, especially tightness in the midbass, are lacking. On the Sony, there is a veil to the sound that's substantially more pronounced than what I heard on the Little Dot. Going between the Sony and the Little Dot, I just thought "eww," though the Sony did have more bass impact. I'd put the CMOY above the Sony, clipping aside. 

Now if I were comparing the Emotiva to something like the Magni or O2, I wouldn't be surprised if the differences were smaller, but I'm only speculating. I haven't heard either. Someone in the Emotiva thread put the Emotiva a small bit above the Magni, but said there wasn't a whole tier of SQ difference between them. I got my Emotiva used for a good price, and it's just much cooler IMO, so I'm fine with that. 

EDIT: Clipping on the CMOY could be because of the batteries? I tested the batteries and they were in the green range of my little battery meter, but they aren't fresh.

It depends a lot on the song, but with no digital volume control, around 12 to maybe 2 o'clock for quiet songs is too much for me. Below 9 o'clock is too quiet on most songs. I usually have it around 11. This is with the 300 ohm resistors.

I do find the midbass on my HE400 a bit loose at times, although I assumed it was just the headphones as people say that they do not need a good amp... Maybe it is the STX don't know..

On the Little Dot, I EQ'd the midbass down about 4 db relative to the subbass. With the Emotiva, my EQ is totally flat except for the treble peaks. FWIW. 

I don't quite understand the science of how amp power vs. gain affects "adequately driven-ness" vs. loudness, but I was getting about 100mw at 32 ohms and 350mw at ~300 ohms (with the resistors) on my Little Dot, and I don't think it was enough.

Another thing is that my STX has a 10ohm impedance and the HE400 are around 40ohms I think.... This would be a damping factor of 1:4.... Although I am not sure how much this can have an effect on planar / ortho.... Usually people say 1:8 or as much as 1:20 with dynamics...

I saw a post from Steve Eddy (I think) somewhere saying that damping factor makes no difference for orthos because their impedance is entirely resistive and they have a flat impedance curve. I'll post it if I can find it.

Ah that makes sense, I think it might be that some songs just have badly recorded midbass that is boomy on any headphones.

hello to all..... I am the very pleased  owner of a pair of he 400..... Very extraordinari headphones for the price...... I amped them with the aune t1 tube amp/ dac but the sound is to bright for me...... I discovered that the Hifimediy dac was a marvellous dac that civilized the sauvage tizz in the high of the he 400...... this dac cost 57 dollars .. i am very pleased by the result.....

nice find bro, i am also a new owner and very satisfied with everything i hear from HE400. I dont even find them sibilant maybe  because im used to vsonic IEMs which are known to be sibilant. I'll grab Hifimediy dac right away:D

Please brother communicate your impression of this dac here..... I want to know if your impression are like mine.... thanks

The new U2 DAC is better from HifimeDIY with internal clock vs the Sabre original, less metallic/jittery and their USB isolator is not that expensive to add to the chain. A truly great budget DAC.
