Thanks for the links, I have seen a fair bit of content from Alpha Audio over the years but don't follow them closely enough to know about this particular review.
32 pairs of speaker and RCA cables measured and listened to
I am not sure if this has been posted here before, but this is pretty interesting.
These guys measured and (blind) listened to, 32 pairs of RCA cables and speaker cables. And found both measurable and audible differences.
