Favorite cable brand.

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.

I like the blind Lama cables there real hairy.

Whatever is under $300 

Cullen Cables makes excellent interconnects and speaker cables.  I love them.

Maze audio makes very good sounding interconnects. 

So far, after owning quite a few over the decades is Wire World, especially series 7 & 8
