Got my today also. I will let it burn for a while before I give any impressions. It doesn't look like it has any big caps that need to burn in though.
EDIT: Can't help myself, will leave some short impressions anyway.
The fiio is (at least before burn in, but I do not believe that burn in will change much) not completely neutral. As other have stated, it definitely gives the sound more body. I especially belive that it has a bumb in the lower midrange as well in the bass. This makes it add just a bit of warmth to the sound.

wow, these amps look pretty nifty!
So any conclusions on the sound quality? i might get one just for the sake of having one!

also just realised on the website it's:
Designed for high impendence and low sensitivity headphones, with bass boost function
which would explain how it may not sound neutral and its ability to drive (to some extent) those bigger cans.

The opamp may be one of these, or a knockoff.
One thing I've noticed about my FiiO -- you know how if you leave a cell phone near a TV or something, it can periodically make a bunch of staticky noise come from the TV? If I carry my FiiO in the same pocket as my cell phone, this happens from time to time.

Just got one off ebay, bid 2p just in case someone else wanted one, but I won it and am looking forward to what it sounds like.

I would not say that the Fiio is an upgrade when used with the D2 and Koss KSC75. It does add a little bit off bass, but I didn't find the added bass very tight. It also does seem to roll of the hights a bit.
So, if the portable player is strong, and the headphones are not too hard to drive, the Fiio will not improve the sound.

does it add volume now or not? first you say that it's almost identical to unamped, then you state that it adds volume. confusing!
what if my onboard sound card has a weak output, will the amp add volume or not?

The cable adds resistance. It does not add volume, it will decrease it with the resistance.

pairing a cowon D2 with the Fiio and a Mylar XBi, there is a definite improvement in terms of soundstage and warmth... so it depends on your earphones too.

Just got mine. It does bring more warmth to the sound, but.... no one else gets this extremely noticeable hissing sound?

Just got it and found it to be quite bassy (warm?). This helps some earphones, like Etys. Fiio surprised me, it has enough power to drive Yuin OK1 and PK1 louder than I want to listen them.
