You should keep the battery. Dac uses battery anyway.

I was wrong on this. I tried battery positive cable unsoldered and dac works with no problem when J1 in shortcut. Probably stress on usb port will be much lower now.

My U1 arrived today.

Using it on (1) Sony NW-A105 w/ Android 9, and (2) Sony Xperia 10 w/ Android 10. Both are working, with caveats.

On the A105, I've only tried the stock music app. As with a xDuoo XP2-Pro, the app asks to access the Zishan. Once I click OK, all audio is routed through the Zishan and so far works as expected.

On the Xperia 10, I initially tried my usual music app Pulsar. Audio was routed through the Zishan, but it seemed like the Zishan was toggle between modes or something -- could hear a relay inside the device clicking, and with the clicks the audio would cut in and out. After having success with the Walkman, I used the Sony Music Center app on Xperia. Like the Walkman's stock app, Music Center requests access to the Zishan, after which is plays as expected.

I haven't tried any other apps.

I do not know if the normal payers really use the full potential of the U1 as the sample rates maybe limited with the standard players. With a player like "USB Audio Player Pro" or "Hiby Music Player" you can make sure the data will be directly forwarded to the USB port.

I'm more picky about user interfaces than sample rates

Plugged into my iMac via USB-C (with the Zishan cable) and without any drivers or fiddling, I'm able to select the U1 as the audio output and seems to work as expected.

Im sorry but i cant understand what you mean in this explanation. A105 to XP2-Pro to U1?

A105 to U1

A105 to XP2

Both behave the same. Walkman app generates a pop-up prompt to request access to the DAC/amp.

Oh, i see. About the SQ, do you prefer U1 or XP2?

Then a simple 10 US$ DAC can do it for you.

IEMs, yes, headphones, ehhh. I’m just sharing my experience homie, not sure where this left-field projection of your values is coming from. If you’ve got a question I can answer by trying something out, I’m happy to try it out. I have access to A105, Xperia 10, Samsung S10e, and Pixel 4XL.

Oh, i see. About the SQ, do you prefer U1 or XP2?

No immediate preference, but I haven’t yet done any A-Bing. Things I like better about XP2: More compact USB-C jumper cable, has a physical power switch (U1 power is all auto, and sometimes bizarre), volume dial spins right-way-round, shape is a bit better for stacking (wider, slightly thinner, height about the same). XP2 also has Bluetooth but i don’t plan to use that much.

U1 works connected to Fiio M3 Pro via USB-C Stacks very nicely.

Yes, XP2 looks good. But, here it priced 4 times the price of U1.

Nice, this is the kind of use case im interested. I want to use my shanlin M0 as transport for U1.

hello guys , can i know which one is LPF and OP amp (red , green) ? i plan to reroll that ICs

I guess you would have a multimeter before attempting such modification. Then, you can track easily AK4493 analog outputs and OPA inputs/outputs. If you don't have SMD experience, I suggest you to avoid that.

Hello Gene6ix,

The green one is the LPF, while the red one is the AMP op amp. I hope this helps.
