Favorite cable brand.

I am very impressed with these cable lines:

1) Zen Wave...Dave's cables

2) Graceline by Black Cat

3) Nordost.

Blue Jeans Cables are my go-to for interconnects and speaker cables, and Pangea for power cables.  I had a set of AudioQuest Evergreens but I sent them back because I thought they sounded thin - I don't know if that's even possible, but in this hobby if something bugs you it's better to resolve it to your satisfaction and move on.  The Pangea cords I use because when I run a voltage tester along them it doesn't detect voltage as opposed to my OEM cords.  Changed out the Bluesound Node 2 power cord for a WireWorld C7 cord.  Thought I heard a difference, don't hold me to it.

Over the years I have used, Transparent IC and Speaker. Audio quest IC and Speaker. Cardas IC and Speaker, Pangea PC, Nordst, ....

A couple years back a friend gave me a set of Raven Soniquil IC to try and now I use all Raven IC, XLR, Speaker and Power. 
Love the No Fairy Dust philosophy, just quality cables at a fair price and you are not waiting 6 weeks (Signal)
