Help me pick some new or used speaker cables

Answer, courtesy of Google Gemini:

Wireworld Eclipse 8 Biwired Speaker Cable (2.5m/Spades): ($2,450) These offer pure Ohno Continuous-Cast copper conductors and OCC Silver Tri-Helix technology, known for clarity and detail. However, they might not provide significant high-frequency damping.

Kimber Kable Carbon 8 Speaker Cable (4.0 Meter - PM33 Spade to PM33 Spade): ($2,200) Features Kimber’s proprietary carbon-based conductor technology for a smooth, natural sound. Their "warm" presentation might offer some high-frequency taming.

Audience frontRow Center Channel Speaker Cable; Single: ($2,475) These cables utilize proprietary VSF conductors for detail and neutrality. Be aware, their neutral character might not emphasize high-frequency damping.

Venom-X Biwire Speaker Cable (Pair): ($2,500) These employ a braided geometry and silver-plated OCC copper conductors for clarity and dynamics. While detailed, they might not specifically tame high frequencies.

Some Cardas cables, particularly their higher-end models, are known for their warm and smooth sonic signature, which might be desirable for taming the upper frequencies in your setup. Some Cardas cables can be quite expensive, exceeding your $2.5k budget.

My answer: buy used.

Sometimes you can find deals at Markertek .  I use them with these bananas.  Please plan to use the heat shrink to eliminate chance of shorts while installing.

Thank you all.  
I’m reading and learning tons on here-I appreciate all suggestions.  
In the interest of building system “synergy” I read that one should consider wires from the same company throughout.  This is tough to do with many of the names here it seems.  Cardas and AQ would be fairly easy, but Cardas golden reference are only avail from a seller in Greece on EBay.  Their interconnects are avail but pricey.   This leads me to AQ and I’m already using their digital cables.  Their stuff is readily avail at numerous different price points.

My pre-amp is an MW LS100 (with fancy tubes)

Amp is Rogue dragoN.  
Speakers are Chapman T-7 (4ohm, 90dB)

I have Rouge Audio M180.

I use Thales - one of the best Investments I made. They were 2.5K when I got them, but still worth the Scratch @ 3.5K..  I did a Comparison with another Brand that was 12K. IMHO Thales was the better cable.
