Could you test rca out too?Not the first oddity with this dac. The thermal performance of the dac chip itself was wayward.

It's already the latest. probably you are not using Mac?Is it REW? The UI looks different from mine. Do you update it to the latest?

Appreciate your reporting though. Does seem like an awkward implementation 'bug'.BTW, a super senior guru PMed me to measure the crosstalk. I measured the crosstalk on each and could not see any issues. both channel's crosstalk values are super low, near the limit of my ADI-2. So it is possible that I'm measuring ADI-2's own crosstalk rather than M500's. so crosstalk is not an issue here.
I packed up both units and will return them to amazon tomorrow. It has already been taking me a lot of time. So I won't do any more measurements.
yeah. all other dacs do not have clean jitter performance. none of the device with AK449x chips performs well, even in USB mode. topping's es9038q2m devices also perform super bad in jitter test. So this really amazed me."gets jitter right" as in what, good performance?
I'm not the Troll herestop this meaningless troll --- otherwise there's no reason for this site to exist.
We are investigating an important issue. this product is clearly fucked up.
When performance is always tested with 2 channels doing the same thing they will never find this kind of error.
But does it remain within the stated spec (THD)D/A converters were always tested right into left and left into right for channel separation and all tests for THD were L,R and L+R, L-R back in the day. Amir's AP can do it all of course.
But does it remain within the stated spec (THD)
If it is within the spec for both channels driven, there is no problem other than a perceived one
When I bought a M500 in 2019 (a little after its release), I did some measurements with a US-366 (it isn't the cleanest interface, but that what I have) and M500 showed a strange behavior at its right channel (high THD at sweep test) I returned it because of this. About jitter, I can get better jitter and THD measurements when the interface is connected to a notebook running on batteries and the measured device connected to another machine (desktop or notebook) which only this is grounded. The measurements are much cleaner this way.yeah. all other dacs do not have clean jitter performance. none of the device with AK449x chips performs well, even in USB mode. topping's es9038q2m devices also perform super bad in jitter test.

look at SMSL M300 coax, for instance. input is pure 12k without lsb.

on M500 this is just super super clean.
