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

You can find that on Amazon. No audiophile blessings, bragging rights  or name brands for the most part  though.  Just nice quality wires for < $100.   

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

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 😁
