    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.
