Supra EFF-I IC's

I was looking for a pair of XLR cables and came across this brand. There are reviews from 5+ years ago but nothing recently. I was considering buying some inexpensive Mogami 2534 based XLR's when I came across Supra in the Audiogon ads and thought I would post here to get opinions from those who may have tried these XLR's.
As it so happens, I am selling a 2m pair of Supra EFF-IX - brand new .. in original packaging .. on ebay as item 190375215706, and starting at $9.90 ... :) Enjoy.
