I'd be plugging the Modi into my computer, the Magni into the Modi, and my headphones (Sennheiser HD 598s) into the Magni.
The answer seems to be a USB A male to B male cable from the computer to the Modi and a pair of RCA cables from the Modi to the Magni. Is this right?
If it is, I was planning on buying this USB cable from Monoprice:
I'm not sure what kind of RCA cable I should be buying, though. Would this work?
Also, if I wanted to connect the Magni and Modi to my PS3 or Xbox 360 S, would I need a Toslink cable?
