USB Digital interface xmos 208 Support PCM32bit/384K DSD256

I'm using PC USB out to feed my AK4396 based DAC.

For USB to SPDIF conversion I use a CM6631a based usb to SPDIF converter.

I'm wondering if a change of the digital interface into xmos 208 384K (see link) would improve the sound.

There are good reviews of the unit on audiophonics.fr

There are three versions of this digital interface available. Does anyone know differences soundwise?

There's also a much cheaper digital interface on Alieexpres

But I'm not sure if it's of the same quality.

Many thanks in advance, for helping me.
