can you help me narrow my speaker cables short list please?

Cables are very dependent upon the equipment on either side.   For my Krell -> GR Research 24 Speaker cable -> XStatic Electrostats the pairing works well.   For my Nad M33 -> Cardas Clear -> Totem Element Metal V2, I preferred the Cardas.   I don’t think there is a right answer, just experiment and see what sounds best to you.

I do love the look of my chord music cables,  very white with sparkling effects. Might be hard finding a pair for a grand 😁

From your list of options: CHORD ODYSSEY X ….. highly recommended 

I use them too in my “B” and “C” systems.

Townshend Fractal F-1's might be better than all those. 

If you like the cables you already have, go the eBay or Amazon and search for braided nylon sleeving.  There are some white ones there.  It will cost very little.  Then just finish them off with heat shrink tubing to fasten the ends.

Go to any YouTube for DIY speaker cables and you can see how it's done.

GR-Research's website also sells a white DIY speaker cable kit that is high quality and great value for the money..
