Favorite cable brand.

Signal cable 
Affordable yet excellent!
improved my sound greatly

Ansuz C2 power cables, Sablon Audio USB and ethernet and WAVE Storm BNC. Considering trying Sablon Audio power cable and XLR interconnects as I have been impressed with the Sablon Audio cables I have tried so far.

I use Cardas cables throughout my system. I have tried several other brand of cables, but I seem to gravitate back to the Cardas sound and build quality. I am currently using Cardas "Clear" interconnects, coaxial, and USB cables with an old set of Bi Wire Quadlink speaker cables. I would like to move up to their top level "Clear Beyond" cable but that will have to wait for a while. lol

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.
