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 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.
My source is my iMac playing lossless and 320mbps AAC files, sent out through USB to the E9 with the E7 docked, acting as the DAC.
I initially just wanted a place to put my E7 when I come home from work at night. The E9 is a convenient charging cradle for the E7 and the 1/4 inch jack is a bonus, as my home headphones (Sennheiser HD558's) have a 1/4" jack. But I didn't think my Sennheiser's actually needed more headroom than the E7 by itself already provides.
And I can't really tell that the sound from these headphones is improved by addding in the E9... I *think* the bass may be a little punchier but it's subtle. The sound from the combo in general is fantastic.
Regardless, the sound is in no way diminished from adding the E9 to the E7 already in use, it may be better, but what is definitely better is the convenience of having a permanent headphone "station" on my desk, one that also charges my E7. And the analog volume knob on the E9 is also very helpful. The construction is solid and reassuing with one caveat...
The 3.5 mm socket is as flaky as you've heard. Jiggle the cord a little and the sound gets staticky or cuts out. You should be using the well-made 1/4" anyway, with an adaptor if necessary. Fiio put a resistor on the 3.5 mm socket which raises its impedance to unacceptable levels (30 ohms, I hear), damaging fidelity. Even the 1/4" at 10 ohms is probably too high, though with my 50 ohm Sennheisers I can't tell... they sound great.) So when buying this, just assume you are buying an amp with only one 1/4" jack and treat the 3.5 mm jack as if it doesn't even exist.Read more ›
