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

You left out a very crucial details for any useful advice - what components do you have in place, particularly speakers, preamp and amp; and what sort of a sound appeals to you most?

You will save a LOT of money if you build your own speaker cables out of CAT 8 cable. They sound great.

15’ +; 15’ - is 30lf for one cable. x 2, you need 60lf

here’s 75 lf white Cat 8, oxygen free copper

cut the ends off, strip and twist/crimp the 8 copper strands, attach them to these banana, or spades

8 strands 26 awg is equal to 17 awg.

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.
