Product Description
Manufacturer's Description
The FiiO E9 desktop headphone amplifier offers truly stunning audio performance and versatility.
The E9's sleek and modern form factor, while minimalist in apperance, belies the engineering marvel within. The E9 has exceptionally low noise and distortion, providing enough power to drive the most demanding headphones up to 600 Ohms with excellent dynamics and clarity.
The FiiO E9 also serves as a dock for the FiiO E7 USB DAC and portable amp. When combined, the E9 and E7 becomes a seamless high fidelity audio interface for any computer, allowing noisy internal sound cards in computers and laptops to be bypassed. With both a fixed and a volume controled line level output, the E9 functions well as a pre-amp for driving power amps or active monitors.
Product Description
FiiO E9 Portable Headphone Amplifier The FiiO E9 is a full sized headphone amplifier. Its unique design allows for the docking and charging of the FiiO E7 DAC. With two audio jacks a 3.5mm and a 6.5mm you can chose the output to suit your preference. The 3.5mm plug this jack has a lower output range for 5dB under the same volume condition to prevent the headphone or hearing damage due to the high range of output. The gain switch allows you to customise the output your headphones receive - pull the switch upward for high gain suitable for headphones with high impedance or low sensitivity; or flick it down for low gain suitable for low impedance or high sensitivity headphones. The Line left and right line out ports allow you to hook up your desktop speaker system to your new E9 amplifier which will deliver the ultimate audio experience. Get the most from your music with the FiiO E9 - check out the features below... Two channel power output suitable for both of headphone with 3.5 and 6.35mm.

I already owned the FiiO E7 DAC and thought I'd give this headphone amplifier a try since it acts as a dock for the E7. It's an interesting, relatively inexpensive device with a few inbuilt annoyances.
The E9 can drive headphones with impedances up to 600 Ohms, and has a gain switch for alternating between high- and low-impedance headphones. The number of connections is good: there are two headphone ports (3.5mm and 6.35mm, the former with -90dB output range to help prevent hearing damage), two line outs (RCA and 3.5mm) and a line in (3.5mm). The only thing that's missing is a USB port for a USB mic. The line outs will only work with active speakers or speakers connected to an amplifier.
These line out ports also provide the biggest annoyance for me: the volume on the RCA connectors is fixed, whereas the 3.5mm jack's volume is variable using the E9's main dial. I would have preferred it to be the other way around. The way it is, if you want to connect to speakers via RCA it means using the speakers' volume control (which in my case in located on the back on them) instead of the E9's nice big, easily-accessible dial. The second annoyance is the power LED. For some reason it's tucked underneath that nice big, easily-accessible dial. Dependent upon where the E9 needs to be placed, the power LED won't be visible for many people. Even though the E9 is designed to work with the E7, the two devices don't work together in an optimal manner (third annoyance): when docked, the E7 doesn't automatically switch on and off with the E9.
These irritations, however, largely pale into insignificance when compared to the improved sound quality/amplification the E7/E9 combo provides over the E7 on its own, and the convenience of having a desktop charging dock for the E7. If you already own an E7 the purchase of an E9 is a definite no-brainer.

Well i've had this a month and initially i disliked the sound coming from it.
The reason for this was my ears (and brain i suppose) had become accustomed to the E7'S Bass Boosts on 2 or 3
So i decided to persevere with this E9 because if i was becoming a "Bass Head", i wanted to be cured ASAP.
Construction quality is lovely.
The 15 V DC Switched mode Psu is rated at 1.6A - enough to keep this running even when charging the E7
On its own I think its a remarkable accurate analog amplifier,pretty much silent - there is a *tiny* amount of hiss detectable on absolutely full volume using line in,but i can only detect that with no audio signal,absolutely no hum.
On docking the E7 - this is where the fun begins!
Forget what the E7 sounded like on it's own - it sounds totally different when docked on the E9.
I found the Pre-out from the E9 on full volume isn't at the same volume level as the E9's fixed line level,it just falls slightly short. Equalization is a little different on pre-out too
The Volume control didn't initially make any noise,after six weeks there is a little noise there on adjusting the pot.
If it were to get worse i may use a potentiometer cleaning spray,but right now it's not bad-and i hardly need to adjust the volume.
Line out level is really good - very detailed and stereo separation pretty much up there with Hi-fi I've literally spent hundreds on in the past.
When listening via headphones - it will disconnect line output.
It's taken a month - but i wouldn't be without this now.
I would strongly recommend that anyone considering this unit,that you spend a few weeks trying out your favorite headphones and listen to everything in your collection you really like.
This will allow you to decide if the E9's "sound signature" is for you or if you would prefer to go down the Valve Amp Route - which can get a little expensive with very minimal improvements.
I don't think most people using the E7 and this will find they dislike the line out sound quality or the E9's ability to drive some of the worlds most insensitive high impedance headphones with a smile on its face.

I have read most of the reviews on this item but seeing, mainly hearing is the proof of the pudding. I already had the Fii0 E7 now the E9 makes a perfect addition to my setup. To date I have been unable to use my Beyer DT 770 headphones whilst listening to my MP3 players now a new world has opened up for me once again. Now I have all the power and more, with such quality of sound any reasonable person could wish for.
A great product at a very reasonable price for all that one gets. I wholly recommend this, and suggest if anyone is in the market for such an item to get it before the price goes up.
