    Those micro USB sockets on MP3 and other portable players are becoming your trademark like those e-caps are. These new audio devices thanks to the Neodyium supermagnets are getting more powerful than before. Like those new TV soundbars that replace the poor internal TV speakers with much better sound. But I do not understand why people would even consider paying 700 dollar/euro for such an amplifier!

      Yes, just a marketing gimmick based on the mistaken notion that quality will be better with higher price, which is not true in all cases.

    How could they possibly damage the charging port so badly?

      Could have dropped the unit when connected to charger or tried to insert upside down!
