Recommendation for a replacement speaker cable

$600? Better than AZ Satori??? Uh, good luck with that one. Try Audio Envy I guess. What specifically are you looking to improve upon over what the AZs do?  “Upgrade” and “Magic” don’t mean anything, at least not to me. 

Wireworld Eclipse,has many pluses others don’t have.
their- OCC  7-9s Copper the purist there is ,
their dielectric even  better then Teflon ,their speaker cable 
is a awg 9 for a 2 m retail $1500 Galen Carol audio very well versed and respectable deals.

I'm running Bluejeans Canare 4S11 on recommendation of my speaker builder (Fritz Carbon 6), PrimaLuna tube integrated.  Couldn't be happier.

Solution: small diameter solid core strands, individually insulated, twisted, within exterior jacket

= Harmonic Technology....small diameter solid core OCC rods in air-foamed PE.

OP's goal:

achieve the magic that combination of the LM and the Spatials have the potential for

With all respect, you asked an arbitrary question that few here would have a specific understanding of so what you are getting is a bunch of responses from people recommending cables that have worked for them in their systems.  Help us understand what "magic" means to you, i.e., specifically, what don't you like about how things sound now, and what would you like to achieve by changing out speaker cables? 

BTW, I rarely hear of a change in cables making a fundamental change to how a system sounds.  More often, the effect of changing cables to chase a sonic goal is similar to dropping your money down a hole, IMO.  My suggestion would be to try the Canare 4S11 recommended here (or maybe the Furez 12AWG 4 Conductor Speaker Cable for about $1/ft.) as a baseline and then if you don't like how your system sounds look at your components or speakers.  In the past year, I have changed my amplifiers and my DAC, and either of those changes had a way bigger impact than any speaker cable change I have made in over 20 years.
