    Hello, it is possible to always make a quick charge on the sp1000 without damaging the battery in the long term, or it is advisable to carry out a normal charge from time to time?
    Thank you

    Congrats Musicbee is the best player and music manager on a PC.
    Connect the SP1000 via USB.
    On MB you should see it appearing under Device using MTP

    Take a look at this video to understand how to.
    Keep in mind that you have to manually chose on which drive you need the sync to be done.
    Playlists transferred on the SD card need to be manually moved (cut & paste) under the file explorer on Windows to the SP1000 default playlist folder on the internal memory
    This is a best working solution so far.

    If so, we can ask for a new fw with optional ON/OFF fast charging function (as some flagship phones of samsung)
    If it is true that fast charging is harmful, we can ask for new fw with optinal ON/OFF fast charging function as like samsung does on their phones

    Sorry off topic.

    Pls any one have 2.5 balance cable of AK120,240,380,.... any model of AK that look like in the pic, can confirm for me ?
    Pole with name "G" is linked to what pin of 3.5? (Only G? Or all RLG?).

    Thanks in advance.

    What... are you serious? ..... I am only asking if is safe to make always quick charging using a quick charger or is more safe to make a charge with a normal charger sometimes, there's no need to have a on / off you want fast charging use quick charger you want normal use a regular charger

    Are you serious?
    Idk if fast charging is a harmful too.
    But on samsung phones have option to turn off fast charging. When set off, it will charge normal (slow) with any charger.

    Back to reality. Fast charging has been ok'd for charging here by Jason several times. The only thing not to do is completely discharge your battery before recharging. Fast, slow, no big difference as long as you use appropriate chargers.

    I would prefer a feature that disables the charge when the USB is plugged in while the SP1000 is used as DAC,
    SPDIF is disabled when in DAC mode.
    Cowon Plenue 2 has both features

    I am using pure silver 10 wire cable; 8 wire for 2.5mm balanced and 2 wire for 3.5mm for ground to connect sp1000 to mass kobo 424 which has a pentaconn input (R+R-L+L-G).

    Please see the schematic diagram below


    I hope this helps

    Thank you. I also though G wire is carried out by G pin of 3.5 for ak daps, so I welded correctly.
    Your pin map pics is again confirmation

    Why you need grounding ? İ need a cable to connect SPK to an headphone amp - balanced/rca - and to a pre amp rca only

    Just FYI. As stated earlier, the German distributor already answered during weekend. I sent my device in on Monday and yesterday I received a brand new SPK. Both, the distributor and the local service center did a great job. I am, although I was shocked to see that happen, a very impressed customer :)

    I connect spk to head amp also but I need grounding.
    Try max vol on head amp, try volume zero on spk. Under that condition I can check grounding matter. When I stop spk and touch a key to metal body I can hear noise gennerated. So I connect ground of spk to ground of head amp.
    But, even no ground, when I press play (volume =0) noise is zero. I think balance works when press play, even no ground.
    For sure I still ground them.

    I got a blue SP1000M a couple of days and really enjoy it with my Abyss Diana first using their standard cable (3.5mm). I just made balanced cable with some old DIY interconnects I had left over and I am just amazed how much better balanced is sounding. Not subtle at all! In all the evaluations I see not much discussion about balanced vs. single ended.
