Recommendation for a replacement speaker cable


I believe this is my first time ever asking speaker cable advice, so bear with me.

System is:
Spatial Audio M3 Turbo S speakers
Line Magnetic 518ia integrated
LFD LE phono
Oppo105
AZ interconnects
Decware Styx speaker cables

I've had AZ Satori, Mapleshade Double Helix, and Clear Day Silver speaker cables. Looking for an upgrade under $600 new or used for the Decware Styx I'm running now. I'm not biased against BlueJean or Canare or Silnote or any other non-boutique brand; just a cable that will help me achieve the magic that combination of the LM and the Spatials have the potential for.

@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.
@mitch2 I'm hoping the Pro 9's err on the warm side of neutral and a little rolled off on the highs.
@mitchellman1 -- How would you describe their presence to the sound as compared to other cables you've tried?
Be suspicious of any cable manufacturer who sells any remedy for skin effect attenuating treble. 10 Feet of solid 8 gauge cable changes resistance on the order of hundredths of an Ohm from DC to 20 kHz. In series with a 4 Ohm speaker, skin effect makes 20 kHz 1/00 of a decibel. For stranded cable this effect is even less. Ribbon cables or litz construction do not improve the sound. You may be susceptible to placebo effect costing you thousands of dollars.
