ifi LAN iSilencer

I discovered this Ethernet signal purifier for network audio streamers, just by chance, while surfing the internet.  I have an extremely highly resolving hifi system.  After reading all the positive customer comments and reviews, I said to myself, what the heck, only 89 bucks, let's go for it.  After receiving the ifi, as recommended, I plugged it into my audio switch, then plugged one end of the ethernet cable into it, and plugged the other end of that ethernet cable into my DAC/Streamer.  Now, I already have a variety of audio tweaks throughout my system, including my speakers.  But when I added the ifi, the background got even deeper, darker and blacker.  It was absolutely amazing!!!  This little gizmo worked exactly as advertised!!!  Highly recommended.
