Ok got the fun and already installed the earth module, but i am kind of new to this stuff, so whats the best connection method to use. i have a S/PDIF port on my soundcard, but it cam with a TOSLink cable so it wont fit in the output on my soundcard. I was also wondering, when you use optical, does the dac of the amp automatically take over or is there something else that needs to be done to use the FUN as a dac and an amp. Any help is appreciated.
