The FiiO A5 is an amazing combination of good headphone sound reproduction, build quality, and fighting power at a very affordable price. It is an upgraded version of two of our customers’ favorite amplifiers, the FiiO E12 and FiiO E12A, with the “E” series replaced by the “A” series. In terms of sound quality, the A5 is now rated higher than the E12, the latter being more affordable.
The amplifier is one of the company’s portable headphone amplifiers, and like its other products, it’s well built. The controls work well, the volume control increases the volume smoothly, and the sound quality is good when playing lossless audio formats. Power and volume are excellent. If you want to boost the volume of high-impedance headphones or improve the sound quality of low-impedance headphones, this is the amp for you.
