I tried that, and strangely enough I get slightly worse results going RME->EMU than RME->RME. Also most of the roll-off of the EMU seems to be in the ADC, because going EMU->RME gets rid of almost all of the roll off. The EMU also has slightly rolled-off bass compared to the RME.
I am really starting to think these tests are only useful to make sure there's nothing wrong with a card after I mod it. They sure as hell don't predict the sound quality changes I have heard.
