The Magni is a headphone amp only: RCA inputs (various sources, whatever you want to amplify) and a 1/4" headphone output.
The Modi is a DAC (digital-to-analog converter) only. Basically, it's how you get a better quality (music) signal from your computer.
They go great together, complement each other, etc. .... but, you don't need both -- each will work without the other. Just depends on what your system requires (I'm a little unclear of your rig).
Generally, "music quality" is improved by using an outboard DAC such as the Modi, because from what I understand, the actual DAC chip, etc. in a dedicated DAC will be better quality/ be isolated/ quiet, etc. -- as compared with the (cheap?) DAC circuit built-in your PC.
Hope that's of some help.
