I have had a portable amp (headbit) ever since I purchased a pair of Sennheiser HD 650s a couple years ago. I have been shopping for a desktop amp ever since but could not pull the trigger as every amp I tried for under $300, either distorted the sound from the headphones or it did not have enough power to drive them. There were a few amps I really liked in the $300-1000 dollar range but had difficulty in justifying spending that kind of money. I already own an E5 amp and use it when traveling to add some power for my Senn HD590's. I was impressed with that little guy that cost me $22 and nearly sounds as good as the bithead with the 590's (the E5 does not come close to driving the 650's properly and now that I have the E9 neither does the bithead portable) so I put the E9 on my wishlist for the holidays and Santa delivered it on Christmas morning.

This amp is fantastic and rivals a couple of the $500 desktops I have auditioned in the past. Good clean and natural sounding with plenty of power to spare. The sound is fantastic, a big step up from the bithead(portable) from a music detail and power standpoint. Am re-enjoying my entire music library.

If you have some hard to drive headphones, and like me could not justify spending $500 for a decent desktop amp, the E9 is for you. For the amazon price tag of $129, you really cannot go wrong here. This is one of the best bang for the buck items I have owned in the past couple years.

I bought a Sennheiser HD 650 and tried it both with a home theater receiver and a stereo receiver for several months. The headphones sounded great with both of the units, however I still wasn't that satisfied with the headphone. I eventually purchased the FiiO E9 headphone amp and I now realize both of those receivers were not properly driving the phones. They truly sound amazing now and I feel their price tag is finally justified. I really can't believe how such an inexpensive item can make these phones sound, but it honestly is an outstanding unit at an even more amazing price.

FiiO E9 Desktop Headphone Amplifier and Dock for E7 USB DAC

I received the FiiO E9 in the mail a few days ago and have been listening to my iPod with the FiiO L3 Line out dock through my Denon AH-D2000 headphones at every available opportunity since then - I have to force myself to take the cans off my head. I am utterly astounded by what I am hearing. I've owned the Denons for over a year and they've never sounded like this before. It's like listening to music through quality headphones for the very first time. I'm not exaggerating. I own the Electric Avenues PA2V2, the Headroom Total Bit head Amp/DAC, the FiiO E5 and the FiiO E11. These are all good products, but the E9 makes a complete mockery of them. I can hear every track with unprecedented clarity. The percussion tracks are particularly distinct and realistic. The bass is visceral - subtle, never booming. The vocals sound like they're originating in front of my face. The truly exceptional soundstage of the Denon AH-D2000's has finally been liberated. I've noted that headphone amp audiophiles are often elitist snobs - they insist that one must pay at least a thousand bucks for any serious headphone amp. I'm calling BS on that. I just ordered the E7, which pairs with the E9 and picks up the DAC duties from the MP3 player. Should be interesting to see if the sound quality can get any better than this. I highly recommend the FiiO E9 to anyone who wants to have their mind blown.

Hello Everyone,

I have been listening and reviewing audio equipment for some time now and I absolutely love everything and anything HI-FI.

I received an early pre-production sample of the E9 from FiiO about 3 weeks ago and I can positively say that this is the absolute BEST value for entry level desktop headphone amplifiers. This is not some marketing scheme or ploy, but an opinion from someone who loves music and audio equipment. I have not yet heard anything that comes even close to the power and sound quality that this little amp can produce. At this price point, you will be getting a lot of bang for your buck and is simply a no brainer if you are in the market for such a product.

Here are my quick Pros and Cons.


-Amazing construction. All aluminum and solid. Lighter than expected.
-Alps volume potentiometer is top notch. Smooth as butter.
-Gobbs of power. Changes your demanding headphones from a wimpy ford focus into a monster truck. Amazing authority and attack.
-Very neutral...presents a TRUE and NATURAL representation of the music you are listening to.
-For a non-balanced amp, this is the BEST balanced sound I've heard from a desktop amp. \
-Completely black when volume was adjusted to 100%
-Some of the most realistic timbre I have heard from any amplifier. Any musical instrument that enters the stage sounds truly just bought a front row ticket.
-Price is ridiculous. I should buy 100 of these and sell them for twice the price. It really is that good.


-e7 dock did not feel sturdy enough for my taste (know that my E9 was pre-production....
