Best Match/Best Synergy?

any standard 14AWG cable will do. Just a decently built one that has the terminations you want, banana cables or otherwise @erastof 

I’d say get two of this - https://www.amazon.com/GearIT-Premium-Braided-Speaker-Plated/dp/B0713ZJDFG/ in either white or black at 10ft (leading to roughly 20ft distance between the two but surely you’d not have the speakers that far apart so the extra is just for ease of droop) 

any standard 14AWG cable will do.

No.  Just…no.  First, what cables/interconnects are you using now, what’s the rest of your equipment, and what improvements/sound characteristics are you looking for?  And what’s your budget and are you looking for new or used?
