The biggest question here for me. What should be a internal sample rate be for?
I want to listen to digital source with the sample rate coming from the source.

Therefore I also don´t need a SRC in a monitor controller.

If the 31 band EQ shall be for room correction - strange.
Also I´m no friend of room optimization software if you want serious monitoring.
For home studios it´s fine.
