Тo be honest, I cannot compare this player with any other player, because this is my first player, but I can share my personal feeling.I should note that Astell & kern SR25 is just remarkable player! it is very ergonomic, not big, comfortable, and it is very important that it is light. I was faced with the choice of what to choose Fiio M11pro or A & К sr 25, I chose A&K sr 25, because firstly it is 2020 based on Android 9 with a good processor and from the reviews I learned that Astell & Kern has a good reputation, their players with very good build quality. The player never heats up even after long listening. Now with respect to the sound. The sound is clear, and rich, pleasant to the ear, works quietly without interference. even not very clean tracks plays cleanly. This player whit a good amount of power! Screen brightness is very good. I also want to mention one more important aspect, the duration of the battery time, it is perhaps the best of all the players on the market today, you can listen for hours and you do not need to think about the economy of time! I would like to warn you that the body of the player is made of aluminum, although it is light and always cool, but at the same time fragile in terms of the fact that the player has sharp edges, it would be better to keep it in its own case, the case is good! And I would like to say thanks to the Bloomaudio team for the fast delivery! Well done guys!
