Fiio A5 headphone amp, titanium finish - the powerful and now even better made A5 combines the power output of the previous E12 amp with the sound quality of the E12a, but priced at the lower E12 price. Finish is even better, with a very smooth sand blasted grey finish and a trick, lux looking volume dial. Battery charging is quicker at 2.5 hours and play time is approx 13 hours. Specs are extremely good for a portable amp, regarding both low distortion as well as high output.
Output impedance is 0.3 ohms, making for an easy match with any in-earphone.
