I have a Gigafoil v4 from DJM Electronics on Shelter Island in San Diego. DJM is an industrial company not an audiophile one. GigaFOILv4-INLINE - EMI/RFI Filter for 10/100 and Gigabit Ethernet I was using it nicely with my Trinnov Altitude 32 SSP for music with the Alt32 as my ROON Ready music player. My theater is down pending upgrade/renovation. Finally I decided to try it out with my Kaleidescape Strato C, also my Alto, in my basement system. All I can tell you is I am a believer. This device is a rectangular steel device, ethernet in, ethernet out, and you simply connect ethernet in from your network switch, and ethernet out to your Kaleidescape Strato C or Alto. And believe me, if you have a 65" OLED or larger, or a top quality projector, you won't be sorry! Both audio and video show nice improvements, the caveat that the better the audio or video in the first place, the more of an improvement at least I noticed. Cost including shipping is $585.00.
