Here are the results cycling through them:

View attachment 23020

Two of them completely overlap so not sure if that is right or wrong.
Probably the red one is non oversampling and you skipped through one of them, maybe try one more time?
The stock/default should be minimum phase, second should be linear phase and third should be non over sampling. I didn't measure the fr but I did measure square waves, they don't seem to be the same.

Is the little spike close to 1k-Hz a problem do you reckon?
Thanks for taking the time to measure the other output voltages :D
I don't see it in my measurements. Probably sw artifacts. I use hf player exclusive mode on my android phone.

The above are 1.7V and 0.5V 1k thd measurements. No 900hz weirdness from here. Using hf player on android playing my test tone file.

I agree. If you have a Shure KSE1200 using this as a DAC with your Android phone is far more compact setup on-the-go. I hope they sell it via Amazon.
db magix ac3 sounds pretty good too. Subjectively better than mu2 to my ears. Check that out.

I tried the type C version and it sounds worse than MU2 plus to me.
Really? I found the mu2 sounds much more artificial. ac3 has better imaging and less fatiguing. But anyway.

I tried the MU2 once and it sounds differently from MU2 plus. However, I think both of them are better than AC3. The AC3 has weak bass so I think it may be related to insufficient power.

Oh right. Firstly I actually have the mu2plus. Secondly, I forgot to mention that i used both mainly as dac. ac3 had excessive output impedance, that will explain the lack of bass control. Actually ac3 more power than mu2 but the output impedance limited the performance. When they are used as dac, problem solved.

I use a Musliand Digital Times. It's the only consumer dedicated PCI-E stereo digital audio transport I've found so far. It even had a BNC output.

The more you talk about 0.5v will just give others potential customers an impression that it is not performing well in higher voltages.
Why would i care? It is a fact. I don't sell or have any relationship with this product. I can say what i want.

Sure you can say what you want, but I don't think the SINAD is bad in higher voltages. Breaking a record at 0.5v is not particularly interesting. That's what I think.

I can also say what I want:p
Well. That's sounds ok to me.

Can anyone link where you can buy this exact version of the musiland plus?

I'm interested in this dongle for work :) seems ideal
