I like the multiple purposes I can use the E17 for. I plan on using is as a desktop DAC after I buy the needed Fiio L7 accessory. I've gotten more power to my portable speakers and enjoyed the results.
Exactly What I Wanted
from Brattleboro, VT
I've tried some of the lower end FiiO devices and they weren't what I was looking for. This one is perfect. It it small, portable and improves the audio quality of everything I've used it with. I also use it to boost the audio signal to my IEM headphones attached to my USB audio recording device when for when I'm recording drums.
Fiio E17 improves iPhone sound
from Livermore, Ca
Was quite surprised to hear how much it improved sound of my iPhone4s (using LOD cable) - It's not subtle. Significantly more clarity. Can hear much deeper into the music. The EQ is useful to balence a recording's timbre. Of course it will play louder - But buy it for the better sound!
Destroys my Dell Laptop sound card
from Lehi, Ut
I use this amp every day at my desk. After several weeks it performs fantastic. If you have a good set of headphones that are underpowered from your laptop, computer, phone, iPod, whatever -this is an elegant solution. I use the DAC to bypass my sound card on my weak laptop and feel like I'm in a concert hall with my audio technica phones.

Because this is an "extra thing", I use it primarily for extended/serious listening, such as a complete movie or album. Prevides great expansive but "neutral" sound quality (a good thing). Rechargeable battery lasts a long time; has never run out in typical use. Instructions provided with product are a little bit hard to follow (translation problems) but not a huge problem.
