Headphone Amplifier Specifications

Amplifier Style
Some headphone amplifiers are designed to be portable and others are meant to be placed on a desk. This will tell you what style of amplifier this item is.
Desktop
Digital-to-Analog Converter (DAC)
A Digital-to-Analog converter (also known as a DAC) converts a digital audio signal into an analog signal. This is especially helpful for listen to music from digital sources, such as iPods and smart phones.
Optional (Accessory required and sold separately)
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.003%
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
Stereo RCA
Input Impedance
This is the input impedance of the headphone amplifier.
16-300 ohms
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
1/4" Plug
Number of Outputs
Some headphone amplifiers have a built-in splitter so multiple pairs of headphones can be connected to it. The number specified here is the number of headphones that can be connected to the amplifier.
3
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
1W-80mW mW
Power Requirement
This is the required way to give the unit power. Common power sources are 120V AC (Common house plugs), batteries, or a combination of the two. If the headphone amplifier uses batteries, this will list the type of batteries that are required. Please refer to the description to find out how many are required for the unit to be properly powered.
15V DC

Very good product for its price!

March 12, 2013

The FiiO E09K is strong enough to power my AKG Q701. The headphones sound "free" or "unchained" compared to a direct connection to my Macbook Pro, which of course does not deliver enough power for those big and demanding studio headphones. I think there are not many competitors compared to the FiiO E09K in terms of "bang for the buck". I'm completely satisfied with the connections, and the big volume knob, which feels sturdy and allows a very accurate volume control. Overall, there is no audible static noise coming from the amp which means the built in components are pretty good. Build quality is also very high.
