However, with all the positive feedbacks that they are gaining from all the products they offer, they continued to create other variants. They are now proud to offer their newest Fiio A5 in the market.

Fiio A5 With High-Quality Build


headphones amp reviewThis Fiio A5 is available in two different colors namely black and titanium. You may also observe subtle differences on this A5 compared to the E12a. The first is more on the chasis type of sandblasted finish of this analog amp that is more refined than the previous brush metal designed of the E12a. The plate in front surrounding the pot has also the slightly more contoured type of finish.

The new Fiio A5 pot is more slimline, less grippy, and a little smoother. It has also a more refined and distinctive look than older knobs. It has constructed its knob for mimicking string instruments with the 56 45 degrees of lies laser that is etched to the center dial with an excellent ring finish. In general, it has nicer look than before.


Fiio A5 review

In line with the I/O’s this Fiio A5 has similar positioning and kind as E12a. It also retained its blue power of LED light configurations and charging on the top left.

It also gains control positioning on the right side of the front plate just beside its pot for a new volume. Its gain switch also stays where it is located the same as the previous analog amp as well as the bass switch.

The left panel is impressively completed by micro USB charging of the female port just a few millimeters down its bass. When you are charging this A5, the LED light just on the top portion of the panel will flick a red color. This is a sign that it is already charging. The light will cease blinking once it is already fully charged.

This A5 also packs look like kind of battery that is the 880mAh li-poly type of battery. This battery offers thirteen hours of power with two to three hours of charging cycle from a full drained one. Take note that the previous battery hours of the E12a is about 20 hours but it is reduced to 13 hours – this is considered to be the best hit.
