    Great perfect, I'll install it as soon as I receive mine then, let you know! :wink:

    Btw, any other places instead where to download the DAC drivers?
    Here you need to be registered to download it seems.. :frowning2:

    Hi, anyone so kind to share the windows USB driver for It as a DAC?
    Cheers

    Goto ATC-HIFIs site here:
    http://www.atc-hifi.com/faq-2/

    Then under Download Firmware:
    Choose HDA-DP20
    Its not firmware but usb DAC drivers
    The HDA-DP20 is exactly the same unit as the xuelin ihifi990 in a slightly different case, infact its what i have

    Cheers

    very kind indeed, thank you! (unfortunately I have a "quirky" PO output which needs repair, but I can try to use the LO with an external amp and use the DAP as a DAC :)).

    Ps. Btw, I do not get the proper use of blue coax cable...is It provided because of custom connections in the 3.5mm jack?

    Quick question to the owners of Xuelin ihifi990 / ATX HDA-DP20. I have got a DP20 recently and noticed that, after a full battery recharge, the first battery bar drops after 20 minutes of playing music in low gain, with volume around 50. I am wondering if this is normal for this player or if you have experienced the same. I am getting around 8 hours on a single recharge. cheers

    Yeah its completely normal. You may find it slightly better on my modded firmware. The battery drains the same also wether it's playing or paused. I did start looking for a higher capacity battery that would fit but have been on other projects since. I do intend to revisit that as well look at upgraded caps and opamps on this, one of my favourite, players.

    Do you still need your PO repairing ?

    The coax cable is for digital out to an amp. Digital/Analogue LineOut is selectable in the software.

    Many thanks. I have to try the modded firmware. Absolutely love the the SQ of DP20, warm with excellent bass.
     
  9. Matpar
    Yep, so far I am using It mostly with linea out to an amp in fact.

    Not sure how much postage is to the UK but i would repair for free for you (just pay postage)

    Modified my awesome HDA-DP20 / ihifi990 tonight. Bypassed the omron relay, it will help with slight sound improvement but also made room for a second 1000uf Cap :L3000: The power on and off pop doesn't bother me at all, kind of nostalgic, the sound of this awesome DAP is now even more amazing with 2 x Nichicon KW 1000uf in parallel with the original Kemet 330uf.

    thats awsome!

    first time seeing the insides of DP20, im seeing one wolfson DAC instead of two....was that just marketing lie? :p

    Definitely 2 x Wolfson WM8740 DACS in there :) I have 2 x Juicy WM8741 DACS waiting for me to install (needs a little bit of circuit modification, I wish I had more free time)
