Once in a great while when I am scouring for stuff online to try out. I get lucky. I consider the return of my AUNE T1 as a lesson learned but the money I lost in shipping that unit back to China is more than made up for what I saved on this little unit I recently got.
Called a Ha-Info U2. Cost is around $70 for a new one sent from China on ebay. This is what it looks like,.
This one the specs are like this.

DC input : DC18V
Support OS : Windows XP, Win 7 and Mac
Dimension： 120mm x 75mm x 31mm
This one I checked here on headfi to see if anyone had one and indeed I found a few guys saying how good this sounds. It was on sale on Amazon for $43. So I thought why not.. I have been burning this unit in for the last 4 days or so..This unit is soundly in between my Fire Phoenix and the Ele dac in sound. All 3 being excellent. The bad news is they don't have any more at all at this price. The unit on ebay is the only way to get one however the one on ebay seems to be an upgraded version of this unit making them worth the extra to get one..The sound is very dynamic, clean and spacious, but is not overly forward sounding or bright like the AUNE T1.In fact this is another reason why I sent the AUNE T1 packing.This little unit has the better sound to my ears. Heck the Ele has a better proper stereo sound over the AUNE T1. I send stuff back when I have to take off my headphone after 15 minutes of use..Fatigue is not what I expect for $200.
The bass end is not as full or as punchy as the Fire phoenix. But detail in music is absolutely wonderful on this, you would never expect coming from a liquidated dac/amp..The Ele combo using the E11 as the amp portion comes really close to this unit both in dynamics and SQ. Using the E11 and Ele dac has a bit more warmth and even more bass end one can set to the bass presets on the E11.Over all I am very happy with this unit as well.. It is very interesting to me that these no name Made in China dac/amps sound so damn good and this is evidence that there is a hidden trove of great sound to be had for the adventurous music lover.. Sure there are risks involved with buying these from China but if you luck out. You end up with a gem of a source like this little unit and the Fire phoenix for not much money.. I think for guys venturing into their first external DAC. The ELE gets the big thumbs up from me. The sound quality is phenomenal coming out of that unit and all it takes for that to sound like this HA-Info unit is a small portable amp to go with it. But even without an amp just the sheer upgrade in SQ from onboard Realtek stuff is worth trying one out.
This HA-Info U2 unit with a change of Op amps I read can and does sound like a much more expensive unit is the word. Something I plan on doing here real soon thanks to Kiteki who pointed out some nice op amps to try out..
