I received my FiiO D5 today, and have posted a short review on VanillaTF2.org.
 

 
 
Conclusion:
 
Pros:
  1. Swish metal carry case
  2. Tiny size
  3. Very solid metallic construction
  4. Multiple outputs including optical and line-out
Cons:
  1. Disturbing headphone hiss, even at low volume
  2. Mic input no better than in-built soundcard

I'll add my impressions here, if you don't mind, BCPK.
 
FiiO D5 RMAA tests: http://rmaa.elektrokrishna.com/index...&search_mode=f

The D5 is unfortunately not a great sound card for headphones. The wonky frequency response on the analog outputs and the very high IMD might not be audible, but the D5 hisses extremely much with any low-to-medium impedance phone. It is completely unusable with any multi-armature IEM, the hiss is almost as loud as the music.

Something like the 70 Ohm Koss KSC75 don't hiss with the D5, but the D5 is way too powerful even for them - the volume button at 0 is mute, and at 1 or 2 it is already too loud for regular listening. Using a 250 Ohm impedance adapter makes the D5 volume control usable with the KSC75... of course one could also change the volume in the audio player instead of on the sound card, but then you throw away the bits and lose a lot of dynamic range.

All in all, the D5 might be useful if you want to drive something between 300 Ohm Sennheiser HD6x0 and 600 Ohm Beyerdynamic DTxx0. Not so universal.

The line-out is volume-controlled, not fixed - and it actually works much better for IEMs than the headphone-out. The S/PDIF-out is quite good, as expected from a digital signal.

I'll post the FiiO E10 RMAA results in another thread. The E10 is basically excellent, and if one's in need for a quality USB sound card-slash-headphone amp, save your bucks and get the E10 over the D5.

That's the problem. It's difficult to see a purpose for the D5 especially with its performance. Maybe dfkt can suggest something.

Not really. The headphone-out is a total failure, the line-out is better to attach headphones to, but I could just use the Realtek onboard thing in my netbook as well. The S/PDIF out sure comes in handy when you want to connect your laptop to a reveicer or something... I dunno, I don't do that.
