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.

Kimber Kable 12 TC, have around 30 hrs in biwire configuration with my Monitor Audio PL300 ii and Krell K300i, so far very detailed and lots of depth, very nice speaker cable.  
At under $100, the Speltz Anticables are WAY beyond the others.  I had a hard time beating their sound until I spent $700 on a couple speaker cables.  Even then, parts of the sound were no better with the $700 cables.  Beyond that, you'd have to go to speaker cables above $1000 to get a serious jump and they are still very system dependent on which is better sounding.  
Under $600, you should at least try Speltz Anticables in your system.  They were the cable that beat all others tried in my system until I hit on a couple that were new like Cerious Graphene Extreme $640 that you can get well under $400 used and Amadi Maddie Signature at $625 new or under $400 used.

For some reason, taking the advice of someone who's named dorkwad is really troublesome. However, I will try to look past the name.
