Xiaomi from the world of acoustics
The Chinese brand FiiO in the world of audio is in some way an analogue of Xiaomi in the market of smartphones and other equipment. That is, they also do it cheaply and affordable, but the quality never falls below a certain (let's note, quite high) bar.
Amplifier + player dock
The inexpensive FiiO K5 stationary amplifier offers an interesting concept with a dock connector for installing FiiO players in it. This made it possible to save on the cost of the amplifier, using the player's existing DAC. The TPA6120A2 module can lower the output impedance to a negligible level (below 1 ohm) and increase the power, thanks to which it manages to shake even quite demanding headphones. Plus, audiosciencereview experts compared it to much more expensive Sennheiser HDV 820 caliber amplifiers and found that the K5 had almost the same low distortion.
Sound on 4+
Given the binding to an external player, it is not so easy to make an unambiguous conclusion about the sound quality. For example, paired with the FiiO X5 II player and the Beyerdynamic T1 headphones beloved by audiophiles, the K5 amplifier wins back for a solid four plus. The sound is both tight and soft at the same time, with excellent balance and panning. Not a five, because he lacks some little things and attention to detail inherent in thoroughbred amplifiers. Although, for this class, more affordable and not so fastidious ears like the Beyerdynamic DT 990 Pro are probably better suited.
