I recently learned of a brand called Tiglon out of Japan. Apparently they are somehow affiliated with TAD and manufacture TAD's own interconnects and speaker cables for them. I picked up a couple Tiglon cables now that they are available in the USA, and so far am extremely impressed. I don't have any TAD gear myself, from what I've read a lot of Japanese audiophiles enjoy the TAD and Tiglon pairing.
Elrod of course makes amazing products as well.
