One test was done randomly with no knowledge of what type, or which brand was being auditioned. One test was done as a coax vs. optical showdown. In stereo one cable was preffered by all. In 5.1
there was no clear winner. In the face-off coax
won every time in stereo but in 5.1 no clear differences were heard, except strangely enough all listeners preferred one of the 8 cables. In
the face-off we were not told whether it was coax or optical.
