Recommendation for a replacement speaker cable

@pdreher Let us know what you think about the Harmonic Tech Pro 9's.  I suspect you will like them better than the Duelund cables but would be interested to hear how it works out.  I have both here.  I actually like older NOS Western Electric 10 awg speaker cables better than similar cables made from the Duelund wire.  I mostly continue to go back to the HT cables.

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.
