This is my 2nd try to answer the question. Yes, I have just found that my NW-A55 is working with Topping nx4 dsd using L27 cable and micro-usb otg cable with power as shown in the 2 pictures below:
You have to fill in the necessary cables/adapters to connect the red line as shown above.
Here's the final setup below:
It's a pity that connecting directly the Fiio L27 cable to Topping nx4 dsd didn't work. However the above setup works as can be seen that the "volume" of Sony A55 disappears meaning it is accepting the nx4 dac for volume control. My guess that direct connection of Fiio L27 cable to the dac does not work is because the sony is not detecting power from the dac which is why the hub works especially when the power jack is connected to usb power as shown.
I don't see why other wmport based sony players will not work with nx4 dsd with these connections. Good luck to you if you are going to try to connect sony wmport based players to the dac.

Recently had a few occurrences when the NX4 would drop sound on one channel, twice on the left and once on the right channel for me. Turning it off and then back on resets it. Has that happened to anyone else before?

Recently purchased a new unlocked Samsung Galaxy A11 smartphone (for smartphone purposes, not as a DAP) and have to report on great synergy with the NX4DSD. Like I said, the phone wasn't purchased as a DAP replacement, but it sort of has become that, as my X5III, though great sounding, is so slow and laggy in comparison that it's like operating an old PC/XT computer vs. a modern muti-core with tons of RAM. And the A11 is not even considered a powerful smartphone!
Yesterday, as a test, I loaded about 3Gb of DSD (including one DSD 512), local MQA 176's and 24/192 PCM files onto the SD card just to see what the phone itself would do with nothing attached.
UAPP was the player and had settings to Native DSD in DSD settings.
On the phone itself with no DAC attached it played everything and it sounded great. Headphones were Senn PX100's V1. The player simply down-sampled the DSD to PCM. As far as I can tell from UAPP, this A11 smartphone has a hi-res chip, can play everything up to 24/192 and is able to utilize UAPP's MQA plug-in for a first software unfold of Tidal Masters or local MQA tracks.
With the NX4 attached--and I have to say, a very painless operation using the Topping-provided USB C to Micro-B cable--UAPP recognized the DAC and I was now able to play everything as before but now with full decoding of all of the DSD--128, 256 and 512 files on there.
I don't mean to sound like an ad for the NX4DSD, but if you're looking for a smartphone DAC to use with UAPP, this one really shines. With the crushing power advantage of a modern smartphone vs. an older streaming DAP like the X5III, the whole experience goes from waiting and waiting to plug it in and get going, with great sound to boot.

NX4DSD 4 PRESIDENT. 
This is good value for money.
The downside is only micro b type input.

I agree with SR1. I have 2 ha2 se,mojo and a few others. Best bang for buck. A bit brighter than mojo with something like noble khan or katana but plays well with my 64 audio A12.

The bass boost is very nice, when no bass is playing you could not notice any change in the other frequencies, once any instrument with bass plays you can hear the difference. For light bass headphones/earphones like my HD600 or Ety ER4SR this is a really nice feature. I opened the NX4 out of curiosity and the board is really nice constructed, the layout is very clean and the components seems of high quality, no serial or part numbers scratched/hidden/erased like other chi-fi electronics. I used to work in a Harman Manufacturing plant (automotive division) and the PCBA in the NX4 is not far behind the Radio/Amplifier boards that we made for Ford/Toyota/Subaru/Harley Davidson and even Audi. I was very pleased to see that the ground contacts on the chassis are specially marked without any anodised on my black unit, unlike the Xduoo XD-05, which is notorious for the ground connection issues.
It seems that the battery is really easy to replace, only issue would be maybe find a battery with the same shape, as the space with the chassis is very tight.
One word of advice, if you plan to open your NX4 like I did, try to do it only if necesary, as the screws that hold the unit (two long screws) held the front and back panel and alignment of the two with the chassis is very hard, so you may end up with a slight misalignment of the panels.
Has anyone found a suitable replacement battery pack for the NX4? I'm also curious what connector type is shown in @sinquito's photo. It looks like a standard 2 pin JST connector. But they come in various sizes as the following image illustrates:

Has anyone found a battery replacement for the NX4(dsd)? I have one from September of 2018 that I just started using again. So it’ll be 5 years old in just a few months. Just wondering in case I find the battery life to not be all that great anymore.
