I'm wondering is there any sound change using usb vs bluetooth? Let's say the files i'm using is flac 16bit. Like from deezer or just using spotify or youtube.

For Spotify and Youtube? Not really.

If you use full CD quality, then it would be best to stick to LDAC or at least aptxHD, to get sound on comparable level to USB input.

I hear no difference when using my IEMs. All my music are FLAC (not streaming).

USB is always better. But UP2/UP4 are realny grate on BT.

Yeay, finally my up4 is delivered after 6 weeks.. i've tried aptx HD and LDAC and quite satisfied with aptx HD. Not yet try using usb though. For first impressions I'm amazed how clear the sound is. Upper midrange sometime may sounds a bit harsh on my b2dusk.. but i will try again later in my critical listening session.. what do the filter change? Is there any explanation? What i hear is the fourth one is a little bit warmth..

Just sharing some info for people who use shanling up4 via UAPP via USB cable. You should turn off the bit perfect mode and turn on the upsample, otherwise there will be no sound come out to your headphones.

Is it just me or anybody else who have same experience?

Anyone confirm if the FIIO LT-TC1 works with the UP4 or should I get the DdHiFi TC05 instead?
do these dedicated specially designed for usb dac mode cables actually improve quality or will any C to C cable suffice?

Considering how basic is the USB input on UP4, any USB cable will do just fine.

Quick question here. Does the UP2 have car mode? I cant find it in the app so I'm assuming no, but if anyone knows a way to have it auto power on, that would be great.

No car mode on UP2 or UP4. Our charging circuit is not able to be used that way.
Only the new UP5 comes with car mode.

Is there a fix to volume issues on the UP4? Sometimes I get half the volume on it but when I restart my UP4, it's suddenly at max volume capacity again. Volume memory is on in the app and i'm on Version code 1.3.0 on my UP4.
Phone is a Poco X3 and using LDAC.

The UP2 appears to not work with the Fiio LT-LT1 cable. The iPhone sees the UP2 as a device to be charged and posts a notification that it draws too much power. Any chance of getting this fixed with a firmware update?

I just bought a usb C to C and it didn't read my up4. It didn't even wake (charge) the up4. Tried the cable phone to phone, connection worked fine, charge and transfer data.
Any suggestion which cable c to c that worked fine as direct usb dac for my phone?

Should be fixed in latest firmware right?
