Question About iFi AUDIO iSilencer+

I am familiar with USB filtering, but here is my question. I have an Auralic music streamer that connects to my computer network. The music is stored on an external USB hard drive. So, the music flows into the computer from the hard drive as it becomes accessible via the network. The iFi iSilencer + is designed to filter USB that flows out of a computer through a USB cable, on its way to the endpoint. 
It is my understanding that both USB and the iFi device are bi-directional. So, if I use the iSilencer + on an external hard drive that sends a music stream into the computer, will I notice the filtering and gain an improvement in sound quality through my streamer? Has anyone tried this type of setup?
