Jena Labs cables simply amazing!!

I now understand why these rarely come up for sale on the used market.  
Dreamdancer interconnects between pre-amp and monoblock amps...very lush.  But the magical, holographic effect of Stealth Sakra between cd player and pre amp adds to that very important front end.  Worked the way up with BOTH brands.  Lesson:if u dont want to spend $$$, don't demo the better cables!  
Got my Symphony a couple of days ago, and it is fantastic.  Quick question - is the cable directional?  I bought it used, so no literature came with it.

thanks, Scott
