That is not possible to hear a difference between microSD cards. Placebo + Voodoo if someone tell that. In a real world blind testing would no one can hear any difference. Only possible scenario is, if the microSD card is too slow like a very old class 2 and you want to play DXD or DSD256 file with 2 GB or above, it would/could stuck with the playback and this would be a indicator which card is used...
