Coming with the Sanskrit 10th AK4493 Edition, there is also an upcoming SMSL M300 MkII. It seems that there was a measurement requirement for M300 before the forum?

This MKII version should theoretically be improved, but because I have not measured the M300, I decided not to think about it.

Look at things first:

This should be a unit of around $ 200. The surface treatment of the aluminum alloy chassis feels very good, but the processing accuracy is at a general level-if it sells for more than $ 500, I may criticize it.

Okay, the measurement starts:

Wow! :oops: 118SINAD?!

Want to understand why the indicator is higher than the chip nominal(-116)

Thank you for your reminder. I almost ignored this!
I think the measurement data in the official datasheet should be based on the official circuit. And this device should not be completely based on official circuits.

He did mention that they already know how to greatly improve the implementation indicators of AKM chips.
In this way, we have made ak4497 better (SIAND=116dB), even ak4499, later you will know.

So this one has 5v power input which was one of the thumbs down points of the MK1. This could be the DAC for me as would have bought the D50s if it had XLR outs. Does this beat the D50s on performance?

Thanks
