    Let us know the difference between the two once you receive them.
    Looking forward to receive mine soon.
    Fantastic price,quality especially if it sounds better than Clip+, that is more expensive now.

    I'm sorry that's sad to receive a brand new player that fails it that way and so soon. I hope that he seller responds as he must and so you can send it back if no other solution is possible as it seems.

    Sorry to hear this. Is there an option to factory restore the player.

    A master degree in electrical engineering helps... Thank goodness the Zishan is not glued shut like most other players! I did put on my 'I void warranties!' t-shirt ( http://www.thinkgeek.com/product/8f52/ ) and went to work.
     
    Turned out a hardware glitch caused by sloppy soldering on the CPU pcb. [​IMG] A thermal-triggered short at the micro SD slot and I also found two additonal, potential faulty joints. I fixed & resoldered everything and rechecked in the microscope. No issues on the the audio pcb btw.
     
    So its working again! [​IMG] My advise to the Zishan guys is to step up their QA, a short burn-in would have revealed the issue in the factory.
     
    Here are some images of the Zishan guts, just for completeness... [​IMG]

    It's unfortunate it needed a little resoldering at all but it seems like that should have been caught in QC, I agree!

    I managed to break of one of the resistors when trying to get the pcb back in the body, I had to solder it back on lol.

    What were you trying to do? Do you think replacing the capacitors can improve the sound?

    zishan sent back to china for some upgrades. Fingers closed, my soldering skills are a bit far from excellence .. [​IMG]

    What were the final upgrades you went for?
    I might get another Zishan with top best components if i am impressed with sound quality and build.Easier and quicker than sending it back.

    Upg 10 + 15v. I was OK w the stock zishan but count resist the upg temptation

    Zishan can play aac?
     
  12. bzfrank
    No, not with FW 0.4d
     
    My advise is to use
     
    https://www.freac.org/index.php/en
     
    to convert the AAC to FLAC. Size will increase but the process is lossless and the Zishan plays FLAC nicely.

    suport 128gb sd card?
     
  14. bzfrank
     
    Have not tried (only a 32 GB here) but the description for the eBay offer talks about up to 256GB, however only as FAT32.
     
    So any larger microSD card (which comes formated as exFAT) will not work out-of-box but needs to be formated with a tool alike
