This is my first venture in the audiophile world. After reading various forums and articles that recommended the E17k, I decided to purchase one. The compact brushed aluminum case is nice and interface is easy to use with controls to treble, bass, gain and balance. The included cables and accessories are nice, though the only cables I've used the most is the AUX cable and USB cable the most. The only dislike about physically about the E17k is the volume wheel feel loose and inaccurate. On to how it sounds. So far, I've tried the E17k with my Monster Turbine Pro Copper and Sennheiser HD 598, and my friend's Audio-Technica M50x. The difference compared to my onboard PC audio is quite significant. The audio is more tight and much more clearer. The E17k has no problem powering the listed headphones I've tried so far. Overall I'm really happy with the purchase and would recommend it to anyone looking for an entry level DAC/AMP.
Fiio E17k review from Headphone Bar: The upgraded Fiio E17k features a very slim metal case, making it a great portable size. It works as a usb dac for computers, a headphone amp for portable devices and has a coaxial input. The E17k decodes up to 24 bit audio at up to 96k sampling rate over usb, has adjustable bass, treble and balance. The amp section is an improved design using better quality parts and allows 3 gain settings and 60 volume levels + Output impedance is low, making for a good match with sensitive earphones and low impedance headphones.

I did a lot of research and this unit came up continually as one of the best. The design is very simple with very few buttons and connections. I use it with my PC and a set of Sennheiser headphones and the results are solid. It takes an okay sound and gives it the boost it needs.
I discovered his web site by accident while shopping online at a Montreal based headphone outlet. The HeadphoneBar prices are way more competitive and value priced and the service is top notched. Okay back to the Fiio E17. I've had this wonderful all-purpose unit for two weeks and I am pairing it with my AKG K550s (also purchased at the Headphone Bar). To emphasize the E17's versatility, the E17 has been used to 1)upgrade the sound through my wireless Sennheiser RS160 direct from a Samsung 50"Plasma 2) used as a USB output from a desktop computer bypassing the analog soundcard, again the E17's DAC works well here -connected to the AKG K550s 3) used the E17's optical input adapter from the back of my Samsung Blueray DVD player to listen to CDs and watch Blueray movies bypassing a Denon HT amp 4)connect the E17 to a 20 yr old Panasonic portable CD player - remember those? - and the sound blew me away 5)and of course used the Ipod L9 cable to connect the my wife's Ipod. Needless to say I am still looking for more uses for this incredible device. It is made from high quality materials and the form factor is just right for portability. The E17 has adjustable L to R balance control (a plus) and the OLED display is nice (do wish the display screen could be larger). Just like the previous reviewer said " don't have one - get one! p.s. warning to Travis: I will be hanging out at your store at least once a week playing with your toys :)
I wanted the E17 about two months ago but they were sold out every where I looked. When headphone bar had the preorder I jumped on it. After the long wait I received the E17 promptly (great service, as compared to some American sites). While I was waiting for the E17 I had purchased the E10 (computer DAC and headphone amp) and a CmoyBB from JDSlabs (portable headphone amp). If you combine the E10 and the CmoyBB, the E17 would still be better. The best thing about the E17 is that it is the swiss army knife of headphone accessories. You can adjust the treble or the bass +-5 points and plug in almost anything that spits out music. My Shure 840's are a bit dark for me so upping the treble and a little bass gives a good balance. My Denon AH-D2000's are a bit too bright, so turning the treble down made them perfect. Turning the Bass up on my Audio-Technica PRO700MK2 made me cry with happiness. However, these are low impedance headphones (40,25,32 Ohms respectively). My Hifiman HE-500's (planar magnetic) get more juice from the E10 than the E17. But then again the E17 is really ment for portable devices. No bigger than my Ipod classic (with the same battery life), on-board screen, volume controls and treble & Bass control, makes the E17 the best spouse for your Ipod and headphones.
Received my E17 the other day (great service Headphone Bar) and was impressed from holding the box right through to enjoying the sound this very high value device produces. And the Music Bomb T-Shirt was a bonus :-) Very high quality packaging leads one to some anticipation as the box is opened and the various deliverables are taken out of the box. All well packed. The nice velvet top snap bag for the E17 is a bonus. 1) plugged in my Sansa Clip to the aux in and used each of Sony EX70 ear buds (old but excellent); Senn HD535 and ER4P, then did the same with one of my Creative JB3s' and finally my Zune 120. The Senn's loaded the amp but the volume was more than sufficient to drive these. Each of the headphones has their own nuances but all were driven extremely well by the amplfier. I have an aging Xin SuperMini IV headphone amp that matches perfectly to the Etymotics and I would say that the E17 is close in quality. 2) I plugged in the USB side to a laptop and and connected to my home system (Energy speakers, Yamaha amp - pretty awesome sound!). This system has a Cambridge DacMagic with optical input from an older but pretty high quality Toshiba DVD player - it really sets a high bar for the final sonics produced. Without a lot of time and critical listening, the E17 as a DAC did an excellent job, I would say a warmer sound than the Cambridge and maybe lacking a bit of the finer detail but really good none the less. 3) As a DAC I then listened to each of the three headphones and pretty much duplicated what I had heard in the 3 mp3 players (all mp3 tracks are high VBR quality, some tracks are in FLAC which the Clip can handle). Pretty impressive bit of gear that is dual purpose. I would strongly recommend this to anyone looking for a very high value, compact, quality headphone amp and DAC. The build quality is also such that this thing really feels solid so I have no doubt it will stand up to being part of my travel kit.
I just got this with an e9, and I've been playing around with it for hours. Bassboost is clean and treble +/- 10 is a godsend. Works great via usb as my desktop's DAC, even took an optical 192K/24bit input (while docked with e9). Gain between the e9's toggle and using the e17 as a preamp can drive every pair of headphones I own perfectly. The e17's +/- 10 bass and treble settings carry over to the e9, which is great. Overall the e17 sounds amazing, very happy with it so far.
