Good point. There was also nothing I read on Sound Professionals' product description that would indicate it was directional.

Another cable I stumbled acorss with a bit more searching is this one: http://www.worldofcables.com/oscatalog/CreateHTMLPagesItem/45456.htm

Apparently, it has more strands than the Sound Professionals cable and is a bit less - $38.99 per meter. Frankly, at those sorts of prices, it would be interesting to do a shootout of a good coax-based cable, like the DH Labs D-75, and a glass-based coax like the Sonic Wave.

I may do just that. The winner would go on my DVD audio out and the loser could feed my CATV audio connection.
