Timely posting as I just hooked up an iso-cat7 this morning between my router and streamer. I picked the filter up used and it came with a 30cm cable intended to be used on the streamer side. I don’t know which “flavor” SOtM Ethernet cable it is. It may have been the Xmas edition?
Im going out from my modem into an inexpensive 2’ Linkup Ethernet cable from Amazon (I believe @lalitk posted this cable at some point) into my router , then another 2’ Linkup cable >> Iso-Cat7 filter >> SOtM 30cm cable >> Ifi Zen Stream.
so… not a lot of time with it yet, but so far I’m having positive results and noticeable improvement in terms of separation and detail.
