New WAVERSA SYSTEMS release - the LAN-EXT1 and USB-EXT1 passive filter unique to the industry. While the details remain ambiguous due to patent conditions, this military-based technology has proven effective in digital audio reproduction. "This module 'forms an electric field and a magnetic field to remove RFI noise from the LAN cable and noise generated by the digital signal line itself.'" Collin Shin, Waversa Systems.


"Waversa’s WLAN Isolator showed a clear sound quality improvement effect by removing electromagnetic noise from a LAN cable. The biggest change was that the stage background became quieter and every note defined, followed by a wider sound stage, an increased sense of space, and energy; especially the low-frequencies were revived." by Kim Pyeon Audio Columnist, HiFi Club.


These passive filters are supplied with a short-run cable placed between the filter and the destination component of the signal path. The LAN filter itself has no directionality.

"...more resolution of fine detail and speed/dynamics: more "alive" and bass is tighter and punchier." 
 
The benefit is optimal when positioned between commercial equipment and audiophile-engineered equipment.  

The first 50 units are available in N. America at an introductory price of $1000 each. ($1600 if purchased as a set.) The benefits are IMMEDIATE and not subtle as been the universal feedback so far.
