DMP-A6 Sampling rate output

Still learning how to use some of the basic function. Wonder if I am able output sampling rate beyond 192khz. Can A6 able to upsample to higher sampling rate? Just curious.

Using A6 as source and output to external dac. I see A6 detected my dac allow max rate up to 768khz, but I don't see any output rate option beyond 192khz.

Thanks
