A very competent DAP when it comes to sound quality. Absolutely noiseless clear sound with detailed, yet soft tone. Soundstage is big enough and you can distinguish the different instruments and vocals in the room. This is matched with MSR7 Audio Technica, the ATH-M50 ATH-AD700X and Fidue A83 and my old Ultimate Ears Super.fi 5 Pro.
Should I choose the favorites, it's IEM: Fidue and headphones: MSR7.
Pioneer / Onkyo's own media playing rap has crashed a few times but in addition it worked and supplies. The choice was between A & K Junior, FiiO X7 and Pioneer but I do not regret that I chose the latter. Highly recommended!
