Back before he became the main photographer for bunches of audio magazines and stuff, Nathan was fiddling with pretty cool audio gear all day long at TouchMyApps. He loves Depeche Mode, trance, colonial hip-hop, and raisins. Sometimes, he gets to listening. Sometimes, he gets to shooting. Usually he's got a smile on his face. Always, he's got a whisky in his prehensile grip.

    Hi nathan, great review. Just in time when i had a chance to secure one. Just one more thing, what about the usb-dac function? If there is one, I’m totally sold

      I always forget something. I’ll get back with you on that.

    To get USB audio out. Connect powered external Dac to powered off DP-S1 micro USB with an OTG cable. Power on DP-S1 and from the play screen select the “three dots” icon next to the song title. Choose the “triangle with 3 waves” icon in the upper left and select USB audio.

      Its not usb-audio out I am talking about. Yes, I am aware that this dap can be paired to mojo. But can it connect to pc and be used as DAC?

      • Reply October 23, 2017


        I would like to know this too.
        Can i connect it to, say, a macbook, and select it as audio out and then listen with my headphones connected to the onkyo?

        Thanks for the help.

    What about the “Balanced” Line-Out option? Has anyone tested this plugging into a Balanced amp?

      I’ve yet to publish its results, but yes, I have used it with outboard balanced amps as well as driving headphones straight. It does both well, but it is my opinion that the DP-S1 a more impressive single-ended player than it is balanced.

    Hi there!
    Can you measure output impedance of DP-S1 (XDP-30R) for balanced and unbalanced output?

  • Reply April 2, 2018


    Hello, do you know how the DP-S1 compares to its Pioneer XDP-30R twin or to other dual DAC DAPs like Fiio X3/X5 III, Shanling M2S and Hiby R6/3?

    Thank you.

    Any chance this will be compared with an iBasso product e.g. DX120 in the future?
