Favorite cable brand.

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)

+1 Inakustik

Transparent largely used both interconnects and speakercables.
Revelation Audio Labs cryo silver  rj45 i2s ethernet
Wireworlds platinum silver starlite usb

I am a Transparent Audio guy through and through I have tried some other brands and, in my system and to my ears, they fell flat in comparison to similarly priced TA. 

Neutral sound-GroverHuffman.com handbuilt, patented air core insulated, embossed platten rolled wire, etc. power cables, ICs and speaker wire.
Warmer sound and High resolution brighter sound - Verastarr all copper ribbon and the all silver ribbon power cables.  Haven't tried ICs or speaker wire.

Many worse sounding as I am a beta tester.  Worst-High Fidelity cables (all types, many versions).  Dark sounding - Magnan and Kubala Sosna cables

Matching cables to system is important.  Use the Verastarr for COS Engineering D1 DAC, Grover Huffman for rest of the system.
