I have been comparing and contrasting Cardas (my dealer loves them) with Transparent. I have previously used DH Labs, WireWorld, Shunyata, and a couple other. I eliminated the others on your list by research.
By most recent detailed comparisons I found I like Transparent on all my component boxes over Cardas. Cardas emphasizes the bass ever so slightly while reducing the detail… the Transparent are, well more transparent. However, on my amp Cardas Clear Beyond sounds better than Transparent Ref 8… I believe this is because the Transparent emphasize shielding over massive conductors as in The Cardas (the weight of Cardas is much higher). I have tried all levels of Cardas and I am sure the Clear Beyond XL will be worth it. When I get some more money I will be upgrading my Clear Beyon to XL on my amp.
While this is useful in an all Audio Research system with Sonus Faber speakers (my ID), it might not be right for your system. I found that in general Transparent are just that in all cases… Cardas is a touch warm in all cases… all product lines… but ever so slightly reduces detail. This can frequently be good. But with truly perfectly balanced components (sonically) it takes a bit away.
