Help me pick some new or used speaker cables

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.

Fidelium Cables - my next Investment, Maybe..

Clarus Aqua is interesting

I’ve seen conflicting opinions on Mogami forever on these forums.  I’m not sure what to think

Have you tried positioning your speakers differently? Maybe swivel them out a bit if you have them facing your listening position.
