I use it to play my WAV files in my USB drive. Sound is clear and balanced. Only problem is I cannot get it into Bluetooth mode, even though I had bought for the Bluetooth version. Perhaps I was given the non Bluetooth?
player is fast to operate; the dac is good enough. only weaknesses are playlist and type of files supported ; but for normal redbook flac and wav is very gd value for money. pair it with mid level amp(musical fidelity) and speakers(egglestoneworks) also don’t feel significant shortcomings in sound quality
