FiiO A5 Portable Headphone Amplifier Black FiiO has strived to constantly progress and innovate with fresh ideas in the portable amplifier market since its own entry. With the A5 Headphone Amplifier they 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 utilise 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% (lower than the E12A's by 33%) and an improved signal-to-noise ratio of 115dB. All of these factors signify that the A5 has a gain level of close to that of the E12A but has improved channel balance lower noise floor and an overall purer sound. Clean and Potent Power 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. All of these aspects mean that the A5 combines the best of the E12 and E12A amplifiers. Beyond just getting output power near that of the E12 with 800mW at 32 Ohms you also get the E12A's exquisite abilities in reproducing music. And with the low/high gain switch you can enjoy the A5 with all kinds of headphones from the most sensitiv.
