    Hello, sharpi31.

    Since I'm not very knowledgeable in electronics, could you do a step-by-step instruction on your Topping NX1s modification?

    Mark with arrows on the photo, what exactly needs to be changed?

    Thank you.

    See the two large blue blocks at the top middle of the board in that picture? Labeled C34 & C33. Just solder a wire from the bottom metal leg / lead to the upper. One wire for each. Two wires total.

    If you follow the battery cable from the battery to the plug on the board, you'll see that it runs between the capacitors (big blue blocks) and the battery (biggest blue thing). You can nudge it out from between the capacitors and battery to make sure that you don't melt it while soldering the jumpers then put it back when you're done. Not necessary, I didn't, but since you sound a bit unsure its a simple enough precaution to make.

    Would the nx1s work with a phone using googles $9 USB C adapter ?

    You're trying to hook up a phone without a headphone jack to the NX1s I assume? Then yes you should be able to use any type-c to headphone jack adapter not just the semi expensive Google one.

    Personally I'd suggest getting the NX2s and bypassing the phone's DAC completely by using an OTG type-c to micro usb cable but that's a more expensive solution, especially if you have a NX1s in hand.

    I just got a lg g5 and have a nx1s already on order, was gonna use it for a 5th gen ipod but it broke. So i was thinking of using it with the phone. Id still have to order the adapter too.

    No idea if anyone reads this thread soon, but I face an issue with my NX1, it picks up weird hissing and distortions if my cell phone is nearby. I know a the mobile phone signals could interfere but given the metal shell of NX1 the extent could have been low. But it buzzes badly. Any idea?

    I don't use a phone for audio at all but I know there has been quite a lot of posts in this thread about the NX1 picking of phone noise. It's not just yours, it's the deal with this thing.

    Try with another cable, I had extraneous sounds from the smartphone, if it was nearby. I replaced the Topping cable and the extraneous sounds went away.

    P.S. I bought Fiio L16, but you can try any other, the main thing is that it should be better than the Topping cable.

    As others have said, its been commented on quite a bit here that it suffers from EM interference. The newer NX1s does not.

    Sorry @EISENbricher , that was the only drawback of the original NX1. Problem corrected in the latter models 2,3,5 and NX1s. I just got a 1s a few months ago and love it strapped to my C3. But the NX2 is my favorite especially it's form factor:wink:

    Paired to my FiiO X3ii:slight_smile:

    Not to mention it looks like Topping is really stepping up their game with the new NX4 DSD DAC/AMP:beerchug:

    Oh... I think it can't be helped then. I'm not using NX1 with my phone now as previously, but using it with Xduoo player. However the NX1 grabs that interference even from ~1m distance between phone and itself.

    I guess I should just be ensuring more distance then. PS: I'm already using better AUX cable, not the Topping provided one.

    It's inherent to the build and chassis of that amp, I tried better ic's myself to no avail:disappointed: I still have an original 1 but does not see much use these days:rolling_eyes:
     
  13. EISENbricher
    I'll check if I can come up with some hack :)

    I'm sorry guy for the stupid question, do I need to turn on the amp to charge the battery, thanks
     
  15. CapnCook
    Nx1a owner...no....charges via 2amp no matter what...even in use!
