OCIA.net takes a look at the CoolerMaster Musketeer 3 Sound Controller in their latest review. Below is a direct quote from the review:

"Before I go on to actually show you the Musketeer 3, this final note. This is not an amplifier, nor is it actually a pre-amplifier. The output is "line level" output, and is intended to be amplified, just like the output on your sound card. A quality set of headphones plugged into the front will lower the volume level considerably. It is designed to "color" the sound, then you plug it into whatever you normally amplify your PC sound with."
