It's All In The Details
FiiO has strived to constantly progress and innovate with fresh ideas in the portable amplifier market since its own entry. With the A5, we continue this tradition by striving to significantly improve over our previous products, the E12 series. Every last detail of the E12 series has been reworked and revamped so as to create a new headphone amplifier that not only maintains the E12 series' strengths, but also rises above them for an even better product.
Strong Internals Make For A Lively Listen
The A5 continues to use the E12A's highly effective MUSES02 + LME49600 opamp combo. In addition, all major components utilize high-precision metal film resistors. These factors, along with better design and component selection, allow the A5 to achieve a total harmonic distortion (THD) rating of almost 0 percent (lower than the E12A's by 33 percent) and an improved signal-to-noise of 115dB. All of these factors signify that the A5 has a gain level close to that of the E12, but has improved channel balance, lower noise floor, and overall a purer sound.
Clean and potent power is also extremely important to sound quality. The A5 contains a highly efficient, low-resistance power management system as well as dual +/- 11V supplied power. This is a significant increase over the E12A's +/- 7.4V supplied power and gives the A5 considerable power reserve that is unheard of among portable amplifiers. Finally, a +/- symmetrical power supply allows for the elimination of coupling capacitors. What does this all mean for the sound quality? Reduced distortion and increased dynamic range.
A5 combines the best of both the E12 and the E12A (The output power near that of E12 & Exquisite abilities in reproducing music of E12A)
All New CNC Milled Headphone Connectors
For the sake of creating an ever better product, no detail could be overlooked. The headphone connector was no exception. For the first time, we use a CNC stainless steel headphone connector ring, replacing the previously used copper. A plastic ring is pressed into the gap between this connector ring and the rest of the body, ensuring it is seamlessly integrated with zero gaps. Not only is this more aesthetically pleasing, the headphone connector is also sturdier due to the non-existent gaps and the use of harder stainless steel.
The gain switch is an easily accessible lever switch, and a separate bass boost switch provides easy matching to different headphones and music styles. The charging indicator light pulsates according to the speed of charging.
The E12A has a durable unibody aluminum alloy chassis with titanium color.
